Headend Optics Platform (CH3000)OP3524Light ‐Plex ™Optical Narrowcast Demux with BC/NC Combiner (with Optical Power Level Management)The Model OP3524 is a combined narrowcast demultiplexer and broadcast/narrowcast combiner with integrated power levelmonitoring and management capabilities. The OP3524 features four optical input ports (one carrying the DWDM narrowcast services and the other three for either a single four ‐way split or dual two ‐way splits of broadcast services) and five output ports (one narrowcast services pass ‐through port and four combined broadcast/narrowcast ports). Each OP3524 demultiplexes up to four DWDM wavelengths and is available in various wavelength combinations.PRODUCT OVERVIEW•Low loss integrated narrowcast demultiplexer with broadcast splitter and broadcast/narrowcast combiner•Non ‐service ‐interrupting local and remote power level monitoring and management (setting narrowcast attentuation levels)•Simplifies installation and reduces rack space requirements •Eliminates most fiber jumpers normally associated with BC ‐NC combining •Hot plug ‐in/out•Occupies one half ‐depth slotFEATURESOne broadcast optical signal can be equally split four ways or each of two independent broadcast signals can be split two ways, while the narrowcast carriers are separated by a four channel ITU‐grid demultiplexer(on the 100 GHz‐spaced ITU grid). Each narrowcast optical carrier is then multiplexed with one of the common broadcast optical signals and passed to one of the four output ports. DWDM optical carriers whose wavelengths are not dropped by the demux are passed through to the DWDM output port.As new video and/or data carriers are added to the system, or as the configuration of the network is changed, the power levels of the optical carriers can change. To ensure optimal network performance, the optical power level management feature of theOP3524 allows power levels to be realigned remotely via SNMP interface to an element management system or locally via the chassis power supply display or local craft port interface. With the OP3524, broadband networks can be easily expanded by adding optical wavelengths without needing to break physical connections or install optical attenuators to realign the optical carrier power levels. By adding optical narrowcast carriers, the OP3524 allows MSOs to offer new, revenue generating services, such as digital video, video‐on‐demand, high‐speed data and telephony, more easily and cost‐effectively than ever before.RELATED PRODUCTSCH3000Chassis Optical Patch CordsOptical Transmitters Optical PassivesBP Back plates Installation ServicesSPECIFICATIONSCharacteristics SpecificationPhysicalDimensions7.3” D x 4.3” H x 1.0” W (3RU)(18.5 cm x 11 cm x 2.5 cm)Weight 1.5 lbs(0.68 kg)EnvironmentalOperating temperature range–20°to +65°C (–4°to 149°F)Storage temperature range–40°to +85°C (–40°to +185°F)Humidity5% to 95% non‐condensingOptical InterfaceOptical connectors SC/APCInputs DWDM INP (narrowcast content), BROADCAST A, B1, B2Outputs•DWDM OUT (pass‐through of all DWDM wavelengths not dropped)•#1, #2, #3, #4 (combined broadcast and one dropped DWDM NC)Power RequirementsInput voltage12 VDC (100 mA)Power consumption 1.2 WOpticalOptical return loss45 dB minPolarization Dependent Loss (PDL)0.25 dB maxDirectivity55 dB minBroadcast:Insertion loss (including connectors)•Broadcast Input Port A: 7.1 dB max (< 6.7 dB typ)•Broadcast Input Ports B1, B2: 4.2 dB max (< 3.7 dB typ)Uniformity (including connectors)0.6 dB max (< 0.4 dB typ)Passband At any given output port, the pass band for the BC signal transverses the entire C‐band (or EDFA gain band),excluding the NC wavelength to be dropped at that port.Wavelength Passthrough Only 1424.5–1617.5 nm input and outputDWDM Narrowcast:ITU channels dropped See ITU Channel PlansPassband @ 0.5 dB (centered on DWDM ITU grid)±0.11 nmRipple within passband0.5 dBInsertion loss (including connectors)•DWDM IN to #n OUT: 3.9 dB max (< 2.8 dB typ)•DWDM IN to DWDM OUT: 1.4 dB max (< 0.8 dB typ)Paired insertion loss (including connectors) 4.9 dB max (Paired insertion loss measured when combined with a single correspondent 4‐λ mux module,models OP35M4x‐x‐xx‐AS or BP35M4x‐0‐xx‐AS, Ch. yy INP to Ch. yy OUT)Optical channel isolation•Adjacent: 55 dB min (> 65 dB typ)•Non‐adjacent: 55 dB min (> 65 dB typ)Uniformity0.6 dB max (difference between max and min output power across the four output ports)Attenuation range12 dB minAttenuation control step size0.1 dBAttenuation control accuracy±0.25 dBOutput power stability0.15 dB p‐v (on 0‐12 dB attenuation range)GeneralHot plug‐in/outOptical input power range•Broadcast (A, B1 and B2): +3 to +22 dBm•Narrowcast: –6 to +17 dBm/ λ per wavelengthOptical output power range, max•Broadcast (A): –5 to +16 dBm•Broadcast (B1 and B2): –2 to +19 dBm•Narrowcast: –10 to +15 dBm/ λ per wavelengthITU Channel PlansARRIS supports DWDM network architectures with a variety of products on the standard DWDM ITU Grid(ITU‐T G.694.1).

identified about 20million rice SNPs by aligning reads from the 3000rice genomes project with the Nipponbare genome.The SNPs and al-lele information are organized into a SNP-Seek system (/iric-portal/),which consists of Oracle database having a total number of rows with SNP genotypes close to 60billion (20M SNPs ×3K rice lines)and web interface for con-venient querying.The database allows quick retriev-ing of SNP alleles for all varieties in a given genome region,finding different alleles from predefined vari-eties and querying basic passport and morpholog-ical phenotypic information about sequenced rice lines.SNPs can be visualized together with the gene structures in JBrowse genome browser.Evolutionary relationships between rice varieties can be explored using phylogenetic trees or multidimensional scaling plots.INTRODUCTIONThe current rate of increasing rice yield by traditional breeding is insufficient to feed the growing population in the near future (1).The observed trends in climate change and air pollution create even bigger threats to the global food supply (2).A promising solution to this problem can be the application of modern molecular breeding technolo-gies to ongoing rice breeding programs.This approach has been utilized to increase disease resistance,drought toler-ance and other agronomically important traits (3–5).Un-derstanding the differences in genome structures,combined with phenotyping observations,gene expression and otherinformation,is an important step toward establishing gene-trait associations,building predictive models and applying these models in the breeding process.The 3000rice genome project (6)produced millions of genomic reads for a di-verse set of rice varieties.SNP-Seek database is designed to provide a user-friendly access to the single nucleotide poly-morphisms,or SNPs,identified from this data.Short,83bp pair-ended Illumina reads were aligned using the BW A program (7)to the Nipponbare temperate japonica genome assembly (8),resulting in average of 14×coverage of rice genome among all the varieties.SNP calls were made using GATK pipeline (9)as described in (6).SNP DATAFor the SNP-Seek database we have considered only SNPs,ignoring indels.A union of all SNPs extracted from 3000vcf files consists of 23M SNPs.To eliminate potentially false SNPs,we have collected only SNPs that have the mi-nor allele in at least two different varieties.The number of such SNPs is 20M.All the genotype calls at these positions were combined into one file of ∼20M ×3K SNP calls,and the data were loaded into an Oracle schema using three main tables:STOCK,SNP and SNP GENOTYPE (Figure 1).Some varieties lack reads mapping to the SNP position,and for them no SNP calls were recorded.Distribution of the SNP coverage is shown in Figure 2.About 90%of all SNP calls have a number of supporting reads greater than or equal to four.Out of them,98%have a major allele fre-quency >90%and are considered to be homozygous,1.1%have two alleles with frequencies between 40and 60%and considered to be heterozygous,and the remaining 0.9%rep-resent other cases when the SNP could not be classified as neither heterozygous nor homozygous.More than 98%of SNPs have exactly two different allelic variants in 3000vari-*Towhom correspondence should be addressed.Tel:+63(2)580-5600;Fax:+63(2)580-5699;Email:n.alexandrov@.Correspondence may also be addressed to:zhanggengyun@ and lizhikang@†The authors wish it to be known that,in their opinion,the first

2.Distribution of SNP coverageeties,1.7%of SNPs have three variants and 0.02%of SNPs have all four nucleotides in different genomes mapped to that SNP position.There are 2.3×more transitions than transvertions in our database (Table 1).Not all SNPs have been called in all varieties.Actually,the distribution of the called SNPs among varieties is bi-modal,with one mode at about 18M SNP calls correspond-ing to japonica varieties which are close to the reference genome,and the second peak at about 14M correspond-ing to the other varieties (Figure 3).Figure 3.SNP distribution by varieties.The major peak shows that about 14M SNPs have been called in most varieties.The bimodal plot indicates that a fraction of SNPs are missing in some varieties,likely due to lack of mapped reads in variable regions.Table 1.Types of allele variants and their frequencies in rice SNPs Allele variants Frequency,%A /G +C /T 70A /C +G /T 15A /T 9C /G6by guest on November 29, 2014/Downloaded

the MSU rice web site(http://rice.plantbiology. /)(8).To browse and visualize genes and SNPs in the rice genome,we integrated the JBrowse genome browser (11)as a feature of our site.PASSPORT AND MORPHOLOGICAL DATAMost of the3000varieties(and eventually all)are conserved in the International Rice genebank housed at IRRI(12). Passport and basic morphological data from the source ac-cession for the purified genetic stock are accessible via SNP-Seek.INTERFACESWe deployed interfaces to facilitate the following major types of queries:(i)for two varieties find all SNPs from a gene or genomic region that differentiate them;(ii)for a gene or genome region,show all SNP calls for all va-rieties(Supplementary Figure S1);(iii)find all sequenced varieties from a certain country or a subpopulation,whichcan be viewed as a phylogenetic tree,built using TreeCon-structor class from BioJava(13)and rendered using jsPhy-loSVG JavaScript library(14)(Supplementary Figure S2)oras a multidimensional scaling plots(Figure4).The resultsof SNP search can be viewed as a table exported to text files,or visualized in JBrowse.USE CASE EXAMPLE FOR QUERYING A REGION OF INTERESTWe used Rice SNP-Seek database to quickly examine the diversity of the entire panel at a particular region of inter-est.We chose the sd-1gene as test case due to its scientific importance in rice breeding.This semi-dwarf locus,causinga semi-dwarf stature of rice,was discovered by three differ-ent research groups to be a spontaneous mutation of GA20-oxidase(formally named sd-1gene),originating fromthe Taiwanese indica variety Deo-woo-gen.Its incorpora-tion into IR8and other varieties by rice breeding programs spurred the First Green Revolution in rice production inthe late1960s(15).Sd-1is annotated in the Nipponbare genome by Michigan State University’s Rice Genome An-notation Project as LOC Os01g66100,on chromosome1by guest on November 29, 2014/Downloaded from4Nucleic Acids Research,2014Figure 5.Jbrowse view of the SNP genotypes within the sd-1gene (each variety is one row).Red blocks indicate polymorphism of the variety against Nipponbare.Shared SNP blocks are seen as vertical columns in red.The blue rectangle box in the bottom contains varieties that do not have these blocks.from position 38382382to 38385504base pairs.On the home page of SNP-Seek,the <Genotype >module was opened and the coordinates of sd-1were used to define the region to retrieve all SNPs,with <All Varieties >checked to select from all the varieties.Clicking on <Search >but-ton resulted in the identification of 80SNP positions (Sup-plementary Figure S1).An overall view of the SNP posi-tions in the polymorphic panel shows at least eight distinct SNP blocks (Figure 5).In this particular panel group of mostly temperate japonica,two distinct SNP blocks can be seen as shared (Figure 5).Variety information can be ob-tained by typing the name of the varieties you see on the genome browser into the <Variety name >field of the Vari-ety module.This use case is one of the examples detailed in the <Help >module.CONCLUSIONWe have organized the largest collection of rice SNPs into the database data structures for convenient querying and provided user-friendly interfaces to find SNPs in certaingenome regions.We have demonstrated that about 60bil-lion data points can be loaded into an Oracle database and queried with a reasonable (quick)response times.Most of the varieties in SNP-Seek database have passport and ba-sic phenotypic data inherited from their source accession enabling genome-wide or gene-specific tests of association.The database is quickly developing and will be expanding in the near future to include short indels,larger structural variations,SNPs calls using other rice reference genomes.SUPPLEMENTARY DATASupplementary Data are available at NAR Online.ACKNOWLEDGEMENTSWe would like to thank the IRRI ITS team (especially Ro-gelio Alvarez and Denis Diaz)and Rolando Santos Jr for the support in operation and administration of the database and web application servers,and Frances Borja for her help in interface design.by guest on November 29, 2014/Downloaded fromNucleic Acids Research,20145FUNDINGThe database is being supported by the Global Rice Science Partnership(GRiSP),the Bill and Melinda Gates Foundation(GD1393),International S&T Cooperation Program of China(2012DFB32280)and the Peacock Team Award to ZLI from the Shenzhen Municipal government.
