Fiber Driver Modules

The Fiber Driver Modular CWDM system offers two types of data channel cards: the Multi-Rate Transponder and the SFP (or GBIC) to SFP (or GBIC) Media Module. Configured with CWDM-specific SFP (Small Form Factor Pluggable) optical transceivers, and connected externally to the Mux/Demux via optical jumper cables, the channel cards generate and maintain the active data connections.

Deployed along a WDM trunk at customer service points using MRV Communications' passive OADM technology, the Multi-Rate Transponder and SFP-to-SFP Media Module can also be used to create a sophisticated Add/Drop topology.

The Multi-Rate Transponder performs full clock and data recovery (3R) per channel at any user selected data rate from 65 Mbps to 2.7 Gbps (65 MHz to 2.7 GHz). By comparison, the SFP-to-SFP Media Module is data rate transparent and works automatically with any data rate from 100 Mbps to 2.7 Gbps (100 MHz to 2.4 GHz) while performing 2R functions.

Built into every CWDM Modular system is extensive In-Band and Out-of-Band management capabilities, including full support of SFP digital diagnostics as per SFF-8472. Management provides real-time access to information such as transceiver type (protocol, range, vendor, etc.), operating temperature, TX/RX optical power, power supply status, and transceiver supply voltage. Management also provides a means for generating management alerts and warnings when system parameters fall outside of their normal operating range.
