Installation The AFCT-721XPDZ can be installed in any XFP port regardless of host equipment operating status. The AFCT721XPDZ 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 potential damage due to Electro-Static Discharge ESD . Once fully inserted into the XFP cage, the top surface of the XFP module makes contact with the heatsink through a cutout in the top of the cage ensuring an effective thermal path for module heat. Functional Description Transmitter Section The transmitter section includes a 1310 nm DFB Distributed Feedback Laser light source, a transmitter driver circuit and a signal conditioner circuit on the TX data inputs. see Figure 1 Optical connection to the transmitter is provided via a LC connector. The optical output is controlled by a custom IC that detects the laser output via the monitor photodiode. This IC provides both DC and AC current drive to the laser to ensure correct modulation, eye diagram and extinction ratio over temperature, supply voltage and operating life. TX_DIS Asserting pin 5, TX_DIS, will disable the transmitter optical output. The transmitter output can also be disabled and monitored via the two-wire serial interface.

Regulatory Compliance The transceiver Regulatory Compliance performance is provided in Table 2 as a figure of merit to assist the designer. The overall equipment design will determine the certification level. Electrostatic Discharge ESD There are two conditions in which immunity to ESD damage is important. Table 2 documents the ESD immunity to both of these conditions. The first condition is static discharge to the transceiver during handling such as when the transceiver is inserted into the transceiver port. To protect the transceiver, it is important to use normal ESD handling precautions including the use of grounded wrist straps, work benches, and floor mats in ESD controlled areas. The ESD sensitivity of the AFCT-721XPDZ 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 AFCT-721XPDZ exceeds typical industry standards.
