General Description:
This product is a parallel 100 GB/s Quad Small Form-factor Pluggable (QSFP28) optical module. It provides increased port density and total system cost savings. An optical fiber ribbon cable with an MTP/MPO connector can be plugged into the QSFP28 module. The cable usually cannot be twisted for proper channel-to-channel alignment. Electrical connection is achieved through an MSA-compliant 38-pin edge-type connector. The module operates on a single +3.3V power supply. LVCMOS/LVTTL global control signals, such as Module Present, Reset, Interrupt, and Low Power Mode, are available with the modules. A 2-wireserial interface is available to send and receive more complex control signals and to receive digital diagnostic information. Individual channels can be addressed and unused channels can be shut down for maximum design flexibility.
