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 10.52 Gb/ compliant to XFP MSA Rev 4.5. The module is designed for single mode fiber and operates at a nominal wavelength of 1310 nm. The transmitter section incorpo- rates Avago Technologies’ uncooled directly modulated 1310 nm distributed feedback laser (DFB). The receiver section uses Avago Technologies’ MOVPE grown planar SEDET PIN photodetector for low dark current and excel- lent responsivity. Integrated Tx and Rx signal condition- ers provide high jitter-tolerance for full XFI compliance. The internally ac coupled high speed serial I/O simplifies interfacing to external circuitry. The ...

... Installation The HFCT-721XPD can be installed in any XFP port regard- less of host equipment operating status HFCT-721XPD is hot-pluggable, allowing the module to be installed while the host system is operating and on-line 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 potential damage due to Electro-Static Discharge (ESD) ...

... Component Monitoring As part of host system qualification and verification, real time transceiver diagnostic information can be combined with system level monitoring to ensure performance and operating environment are meeting application require- ments. Transceiver Internal Temperature Temperature is measured on the HFCT-721XPD using s ens- ing circuitry mounted on the internal PCB. The measured temperature will generally be cooler than laser junction and warmer than XFP case and can be indirectly correlated to XFP case or laser junction temperature using thermal resistance and capacitance modeling. This measurement can be used to observe drifts in thermal operating point or to detect extreme temperature fluctuations such as a failure in the system thermal control.

... ESD controlled areas. The ESD sensitivity of the HFCT-721XPD is compatible with typical industry production environments. 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 HFCT-721XPD 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 contacted by a Human Body Model probe. ...
