Finisar has introduced a 100G serial FR transceiver in the popular QSFP28 form factor for inter-data centre, transport and router applications with 2km reaches.

Previewing at the recent OFC conference and exhibition in San Diego, the module leverages a standard 4x25G electrical interface, so that it plugs into standard QSFP28 slots, but employs just one serial 100G PAM4 optical channel. Once deployed in sufficient volume, it is expected to replace existing 100G QSFP28 CWDM4 modules. The company also plans to introduce a 500m DR version of this module.

Finisar launched a new product family at this year’s OFC conference in San Diego, complementing its line of coherent components and Analog Coherent Optics (ACO) transceivers.  Called the Integrated Tunable Transmitter and Receiver Assembly (ITTRA), the new product family is heralded as the industry's smallest fully integrated coherent optics assembly.

Finisar announced that it is in full production of its 100G shortwave wavelength division multiplexing (SWDM) optical transceiver, which is compliant with the 100G SWDM4 specification defined by the SWDM multi-source agreement (MSA).

The pluggable QSFP28 transceiver is the first mass-produced module capable of transmitting 100Gb/s over a pair of multimode fibres, thus enabling users to upgrade their systems from 10 Gigabit Ethernet to 100 Gigabit Ethernet without changing their data centre cabling.
