The lead-free and RoHS-compliant small form factor pluggable (SFP+) transceiver from JDSU improves the performance for 8 Gigabit Fibre Channel (8GFC) applications, and is ideal for high-speed, storage area network applications. This transceiver features a highly reliable, distributed-feedback (DFB) laser coupled to an LC optical connector. The transceiver is fully compliant to the FC-PI-4 800-SMLC- L variant and is compatible with 400-SM-LC-L and 200-SM-LC-L variants. It is fully compatible with SFP+ specifications at 8.5 G, 4.25 G and 2.125 G bit rates, with internal AC coupling on both transmit and receive data signals. The all-metal housing design provides low EMI emissions in demanding 8.5 G applications and conforms to IPF specifications. An enhanced digital diagnostic feature set allows for real-time monitoring of transceiver performance and system stability, and the serial ID allows for customer and vendor system information to be stored in the transceiver. Transmit disable, loss-of-signal, and transmitter fault functions are also provided. The small size of the transceiver allows for high-density system designs that, in turn, enable greater total bandwidth.
