Description
120km XFP Transceiver exhibits excellent wavelength stability, supporting operation at 100GHz channel, cost effective module. It is designed for 10G SDH/SONET and 10G Ethernet applications.
The transmitter section incorporates a coded EML laser, and the receiver section consists of an APD photodiode integrated with a TIA, Integrated low power dual CDR with Electronic Dispersion Compensation (EDC). This module can be used to compensate channel impairments caused by either single mode fiber up to 120 km .All modules satisfy class I laser safety requirements. XFP transceiver provides an enhanced monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, and received optical power and transceiver supply voltage.

XFP Mechanical Components

The mechanical components defined:
1. The module, clip and connector dimensions are constant for all applications. While the bezel, cage assembly, EMI gasket and heat sink can be designed and/or adjusted for the individual application.
2. The relatively small form factor of the XFP module combined with an adaptable heat sink option allows host system design optimization of module location, heat sink shape/dimension/fins design, and airflow control. The module can be inserted and removed from the cage with the heat sink and clip attached.
