Finisar announced that it is in full production of its 100G shortwave wavelength division multiplexing (SWDM) optical transceiver. The pluggable QSFP28 transceiver is the first mass-produced module capable of transmitting 100 Gbps over a single pair of multimode fibres, thereby enabling users to upgrade from existing 10 to 100 Gbps without altering the existing fibre infrastructure. The transceiver is also the first optical module on the market compliant with the 100G SWDM4 specification defined by the SWDM multi-source agreement.
Many data centres today carry 10 Gbps optical signals over duplex multimode fibre (MMF), where one fibre is used to transmit a signal and the other is used to receive a signal. When upgrading to 40 or 100 Gbps over MMF, data centre operators must quadruple the amount of fibre deployed if they wish to use optical transceiver modules based on the IEEE 40GBASE-SR4 or 100GBASE-SR4 standards, both of which rely on four fibre pairs (i.e., 8 fibres). The transceiver, system and cabling suppliers that constitute the SWDM MSA have agreed on specifications that avoid the need for this additional fibre, and therefore allow data centres to further leverage their investment in their existing MMF plant.
