PRODUCT OVERVIEW
IBM 8GB SFP+ SW OPTIC TRANSCEIVER

The IBM 44X1964 is a compact 8Gb/s optical transceiver module for serial optical communication applications at multi-rate of 2/4/8Gb/s. The IBM 44X1964 converts a 8Gb/s serial electrical data stream to 8Gb/s optical output signal and a 8Gb/s optical input signal to 8Gb/s serial electrical data streams. The high speed 8Gb/s electrical interface is fully compliant with SFI specification.

The SPP5101SX-GL is designed for 8G Fiber Channel (8.5Gb/s) applications. The high performance 850nm VCSEL transmitter and high sensitivity PIN receiver provide superior performance for Ethernet applications at up to 150m links. The fully SFP compliant form factor provides hot pluggability, easy optical port upgrades and low EMI emission.

This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 6030-01-625-7745, indicating validated use in U.S. government and defense logistics supply chains.
