requirements of EN (IEC) 60825 and the electrical safety requirements of
EN (IEC) 60950. Copies of certificates are available at Finisar Corporation upon request.
VIII. Digital Diagnostic Functions
Finisar FTLF1619P1xCL SFP transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1. It is very closely related to the E2PROM defined in the GBIC standard, with the same electrical specifications.
The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information. Additionally, Finisar SFP transceivers provide a unique enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in E2PROM that is accessible over a
2-wire serial interface at the 8 bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial ID memory map remains unchanged. The interface is identical to, and is thus fully backward compatible with both the GBIC Specification and the SFP Multi Source Agreement. The complete interface is described in Finisar Application Note AN-2030: “Digital Diagnostics Monitoring Interface for SFP Optical Transceivers”.
The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is activated, the serial clock signal (SCL, Mod Def 1) is generated by the host. The positive edge clocks data into the SFP transceiver into those segments of the E2PROM that are not write-protected. The negative edge clocks data from the SFP transceiver. The serial data signal (SDA, Mod Def 2) is bi-directional for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially.
For more information, please see the SFP MSA documentation1 or Finisar Application Note AN-2030.
Digital diagnostics for the FTLF1619P1xCL are externally calibrated by default. Please note that evaluation board FDB-1018 is available with Finisar ModDEMO software that allows simple to use communication over the 2-wire serial interface.

爱人者，人恒爱之；敬人者，人恒敬之；宽以济猛，猛以济宽，政是以和。将军额上能跑马，宰相肚里能撑船。 最高贵的复仇是宽容。有时宽容引起的道德震动比惩罚更强烈。 君子贤而能容罢，知而能容愚，博而能容浅，粹而能容杂。 宽容就是忘却，人人都有痛苦，都有伤疤，动辄去揭，便添新创，旧痕新伤难愈合，忘记昨日的是非，忘记别人先前对自己的指责和谩骂，时间是良好的止痛剂，学会忘却，生活才有阳光，才有欢乐。 不要轻易放弃感情，谁都会心疼；不要冲动下做决定，会后悔一生。也许只一句分手，就再也不见；也许只一次主动，就能挽回遗憾。 世界上没有不争吵的感情，只有不肯包容的心灵；生活中没有不会生气的人，只有不知原谅的心。 感情不是游戏，谁也伤不起；人心不是钢铁，谁也疼不起。好缘分，凭的就是真心真意；真感情，要的就是不离不弃。
这世上，别指望人人都对你好，对你好的人一辈子也不会遇到几个。人心只有一颗，能放在心上的人毕竟不多；感情就那么一块，心里一直装着你其实是难得。 动了真情，情才会最难割；付出真心，心才会最难舍。 你在谁面前最蠢，就是最爱谁。其实恋爱就这么简单，会让你智商下降，完全变了性格，越来越不果断。 所以啊，不管你有多聪明，多有手段，多富有攻击性，真的爱上人时，就一点也用不上。 这件事情告诉我们。谁在你面前很聪明，很有手段，谁就真的不爱你呀。 遇到你之前，我以为爱是惊天动地，爱是轰轰烈烈抵死缠绵；我以为爱是荡气回肠，爱是热血沸腾幸福满满。 我以为爱是窒息疯狂，爱是炙热的火炭。婚姻生活牵手走过酸甜苦辣温馨与艰难，我开始懂得爱是经得起平淡。 爱人者，人恒爱之；敬人者，人恒敬之；宽以济猛，猛以济宽，政是以和。将军额上能跑马，宰相肚里能撑船。 最高贵的复仇是宽容。有时宽容引起的道德震动比惩罚更强烈。
