40/100Gb/s 100m QSFP28 Transceiver

This is a Four-Channel,Pluggable, LC Duplex, Fiber-Optic QSFP+ Transceiver for 100 Gigabit Ethernet Applications.

The transceiver is a high performance module for short-range duplex data communication and interconnect applications.

It integrates four electrical data lanes in each direction into transmission over a single LC duplex fiber optic cable.

Each electrical lane operates at 25.78125 Gbps and conforms to the 100GE XLPPI interface.

The transceiver internally multiplexes an XLPPI 4x25G interface into two 50Gb/s electrical channels, transmitting and receiving each optically over one simplex LC fiber using bi-directional optics. This results in an aggregate bandwidth of 100Gbps into a duplex LC cable. This allows reuse of the installed LC duplex cabling infrastructure for 100GbE application. Link distances up to 70 m using OM3 and 100m using OM4 optical fiber are supported. These modules are de- signed to operate over multimode fiber systems using a nominal wavelength of 850nm on one end and 900nm on the other end. The electrical interface uses a 38 contact QSFP28 type edge connector. The optical interface uses a conventional LC duplex connector.
