PCB Mount Transceiver

10 Mbps – 200 Mbps, MMF, 3.3V

provides the opportunity for Predictive Failure Identification, Compliance Prediction, Fault Isolation and Component

Monitoring.

Compliance Prediction

Compliance prediction is the ability to determine if an optical transceiver is operating within its operating and

environmental requirements. The PCB Mount Transceiver provide real-time access to transceiver internal supply voltage

and temperature, allowing a host to identify potential component compliance issues.

Fault Isolation

The fault isolation feature allows a host to quickly pinpoint the location of a link failure, minimizing downtime. For optical

links, the ability to identify a fault at a local device, remote device or cable plant is crucial to speeding service of an

installation. PCB Mount Transceiver real-time monitors of Vcc, and Temperature can be used to assess local transceiver

current operating conditions. In addition, status flag Rx Loss of Signal (LOS) is mirrored in memory and available via the

two-wire serial interface.

Component Monitoring

Component evaluation is another use of the PCB Mount Transceiver real-time monitors of Vcc, and Temperature.

Potential uses are as debugging aids for system installation and design, and transceiver parametric evaluation for factory

or field qualification. For example, temperature per module can be observed in high density applications to facilitate

thermal evaluation of systems that incorporate this PCB Mount Transceiver

Required Host Board Components

A power supply noise rejection filter as describe in SFP MSA is required on the host PCB to meet data sheet

performance. This is filter incorporates an inductor which should be rated to 600 mA DC and 0.5

Ω series resistance or

better. It should not be replaced with a ferrite. The required filter is illustrated in Figure 4. Also, the host PCB for the PCB

Mount Transceiver

requires 4.7 K to 10 KΩ pull-up resistors for LOS, SCA and SDL lines.
