... AFCT-721XPDZ 10GbE/10GFC 1310 nm XFP 10 Gbit/s Optical Transceiver Data Sheet Description The 1310 nm XFP transceiver is a high performance, cost effective module for serial optical data communications applications specified for signal rates of 10.30 Gb/s to 11.3 Gb/ compliant to XFP MSA Rev 4.5. The mod- ule is designed for single mode fiber and operates at a nominal wavelength of 1310 nm. The transmitter sec- tion incorporates Avago Technologies’ uncooled directly modulated 1310 nm distributed feedback laser (DFB). ...

... Transmitter disable, interrupt, power down/reset, re- ceiver loss of signal and module not ready are also hard wired pins on the 30-pin right angle connector. Installation The AFCT-721XPDZ can be installed in any XFP port re- gardless of host equipment operating status. The AFCT- 721XPDZ is hot-pluggable, allowing the module to be installed while the host system is operating and on-line. The clip-on heatsink is designed to clip on to the XFP cage without a module present. Upon insertion, the transceiver housing makes initial contact with the host board XFP cage, mitigating po- tential damage due to Electro-Static Discharge (ESD) ...

... GND Figure 2. MSA recommended power supply filter Functional Data I/O Avago Technologies’ AFCT-721XPDZ fiber-optic trans- ceiver is designed to accept industry standard electrical input differential signals. The transceiver provides AC- coupled, internally terminated data input and output interfaces. Bias resistors and coupling capacitors have been included within the module to reduce the number of components required on the customer’ ...

... The second condition is static discharge to the exterior of the host equipment chassis after installation. To the extent that the duplex LC optical interface is exposed to the outside of the host equipment chassis, it may be subject to system-level ESD requirements. The ESD performance of the AFCT-721XPDZ exceeds typical industry standards. Performance 500 Volts to the high speed pins, 2000 Volts to the low speed pins Typically, no damage occurs with 25 kV when the duplex LC connector receptacle is con- tacted by a Human Body Model probe. ...
