... Functional Description Receiver Section Design The receiver section for the HFCT-5961TL/TG/NL/NG/ ATL/ATG 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 as- sembly is such that it provides better than 14 dB Optical Return Loss (ORL). ...

... Functional Description Transmitter Section Design A schematic diagram for the transmitter is shown in Figure 2. The HFCT-5961TL/TG/NL/NG/ATL/ATG incorpo- rates an FP laser as its optical source. All part numbers have been designed to be compliant with IEC 825 eye safety requirements under any single fault condition and CDRH under normal operating conditions. The op- tical output is controlled by a custom IC that detects the laser output via the monitor photodiode. This IC pro- ...

Package The overall package concept for these devices consists of the following basic elements; two optical subassem- blies, two electrical subassemblies and the housing as illustrated in the block diagram in Figure 3. The package outline drawing and pin out are shown in Figures 4 and 5. The details of this package outline and pin out are compliant with the multisource definition of the DIP. The low profile of the Avago Technologies transceiver design complies with the maximum height allowed for the LC connector over the entire length of the package. The electrical subassemblies consist of high volume multilayer printed circuit boards on ...

... Recommended Circuit Figures 6a and 6b show recommended dc and ac coupled circuits for deploying the Avago Technologies transceivers in +3.3 V systems. Data Line Interconnections Avago Technologies’ HFCT-5961TL/TG/NL/NG/ATL/ATG fiber-optic transceivers are designed to couple to +3.3 V PECL signals. The transmitter driver circuit regulates the output optical power. The regulated light output will maintain a constant output optical power provided the data pattern is reasonably balanced in duty cycle. If the ...

Figure 8 shows the front panel dimensions associated with such a layout. Eye Safety Circuit For an optical transmitter device to be eye-safe in the event of a single fault failure, the transmitter must either maintain eye-safe operation or be disabled. The HFCT-5961TL/TG/NL/NG/ATL/ATG is intrinsically eye safe and does not require shut down circuitry. V (+3 130 Ω TD- NOTE A 130 Ω ...

... EMI suppression. Avago Technologies encourages using standard RF suppres- sion practices and avoiding poorly EMI-sealed enclo- sures. Avago Technologies’ OC-3 LC transceivers (HFCT- 5961TL/TG/NL/NG/ATL/ATG) have nose shields which provide a convenient chassis connection to the nose of the transceiver. This nose shield improves system EMI performance by effectively closing off the LC aper- ture ...

... Absolute Maximum Ratings (HFCT-5961TL/TG/NL/NG/ATL/ATG) Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parame- ter in isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum ratings for extended periods can adversely affect device reliability.
