The Qlogic PLRXPL-VC-SH4-23-N-QL small form factor pluggable (SFP+) transceiver improves the performance for 8 Gigabit Fibre Channel (8G FC) applications, and is ideal for high-speed, storage area network applications. This transceiver features a highly reliable, 850 nm, oxide, vertical-cavity surface-emitting laser (VCSEL) coupled to an LC optical connector. The transceiver is fully compliant to the 8 G FC, FC-PI-4, and the SFP+ multisource agreement (MSA) specifi cations, with internal AC coupling on both transmit and receive data signals. The all-metal housing design provides low EMI emissions in demanding 8 G applications and conforms to IPF specifi cations. 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.
