AFCT-5745Z Family of Single-Mode SFP Transceivers for SONET OC-48 and SDH/STM-16 with Digital Diagnostic Monitoring DMI Interface Part of the Avago METRAK family Data Sheet The AFCT-5745Z are high performance, cost effective modules for serial optical data communications applications that range from 125 Mb/s to Gb/s. They are designed to provide SONET/SDH compliant connections for 2488 Mb/s at both short and intermediate reach links. All modules are designed for single mode fiber and operate at a nominal wavelength of 1300 nm. The transmitter section of the AFCT-5745xPZ incorporates a 1300 nm Fabry Perot FP laser. The transmitter in the AFCT-5745xTPZ uses a Distributed Feedback DFB Laser. For each device the receiver section uses an MOVPE grown planar SEDET PIN photodetector for low dark current and excellent responsivity. A positive-ECL logic interface simplifies interface to external circuitry. The AFCT-5745Z adds digital diagnostic monitoring to standard SFP functionality, enabling fault isolation, components monitoring and failure prediction capabilities. The diagnostic features allow the host to observe real time temperature, supply voltage, laser bias current, laser average output power and received input average power through the legacy SFP two wire serial memory interface. Conventional memory information found in legacy SFPs is also available in these enhanced transceivers. Hot-plugging is ensured by design and by 3-stage pin sequencing at the electrical interface.

This optical subassembly is coupled to a postamplifier/decision circuit on a circuit board. The postamplifier is ac coupled to the preamplifier. The coupling capacitors are chosen to pass the SONET/ SDH test pattern at 155 Mb/s, 622 Mb/s and Gb/s without significant distortion or performance penalty.

Loss of Signal The Loss of Signal LOS output indicates that the optical input signal to the receiver does not meet the minimum detectable level for compliant signals.

This optical subassembly is coupled to a postamplifier/decision circuit on a circuit board. The postamplifier is ac coupled to the preamplifier. The coupling capacitors are chosen to pass the SONET/ SDH test pattern at 155 Mb/s, 622 Mb/s and Gb/s without significant distortion or performance penalty.

For codes that have a significantly lower frequency content, jitter and pulse distortion could be degraded.

Loss of Signal

The Loss of Signal LOS output indicates that the optical input signal to the receiver does not meet the minimum detectable level for compliant signals. When LOS is high it indicates loss of signal. When LOS is low it indicates normal operation. The Loss of Signal thresholds are set to indicate a definite optical fault has occurred eg., disconnected or broken fiber connection to receiver, failed transmitter .
