Guanglian’s OPTR-MW85S1-C is a four-channel, pluggable, multi-mode, fiber-optic QSFP28 transceiver for 100 Gigabit Ethernet applications. This transceiver is a high-performance module for short-range data communication and interconnect applications. It integrates four host electrical data lanes in each direction at 25Gbps into two optical lanes at 50Gbps giving an aggregated bandwidth of 100Gbps. It allows optical communication up to 100m over a 2-fiber duplex LC optical multi-mode OM4 cable. The pull tab facilitates the insertion and extraction of these transceivers in high density environment. Each electrical lane operates at 25.78125Gbps and conforms to the 100GE CAUI4 interface with host FEC turned off. These modules are designed to operate over multimode fiber systems using nominal wavelengths of 850nm and 900nm. The electrical interface uses a 38 contact QSFP28 edge type connector. The optical interface uses a conventional 2-fiber duplex LC MMF connector.
