... Functional Description Receiver Section Design The receiver section for the AFCT-5942xxxZ contains an InGaAs/InP photo detector and a preamplifier mounted in an optical subassembly. This optical subassembly is coupled to a postamp/decision circuit on a circuit board. The design of the optical assembly is such that it pro- vides better than 27 dB Optical Return Loss (ORL). ...

... Design A schematic diagram for the transmitter is shown in Figure 2. The AFCT-5942LZ/ALZ/GZ/AGZ incorporates an FP laser as its laser source. and the AFCT-5942TLZ/TGZ/ ATLZ/ATGZ uses a DFB laser as its laser source. Both pack- ages have been designed to be compliant with IEC 825 eye safety requirements under any single fault condi- tion and CDRH under normal operating conditions ...

... For an optical transmitter device to be eye-safe in the event of a single fault failure, the transmit-ter must either maintain eye-safe operation or be disabled. The AFCT-5942xxxZ is intrinsically eye safe and does not require shut down circuitry. Signal Detect The Signal Detect circuit provides a deasserted output signal when the optical link is broken (or when the remote transmitter is OFF) ...

... EMI regulatory standard and more importantly, it reduces the possibility of interfer- ence to neighboring equipment. Avago Technologies has designed the AFCT-5942xxxZ to provide good EMI performance. The EMI performance of a chassis is depen- dent on physical design and features which help improve EMI suppression. Avago Technologies encourages using standard RF suppression practices and avoiding poorly EMI-sealed enclosures ...
