Pro Optix has launched a range of 400G optical transceivers to offer customers an opportunity to maximise network capacity. With a launch range of 12 variants, reaches stretch up to 10km and types include DR4, FR4 and LR4. Currently the range includes compatible solutions for Cisco, Arista, Juniper and Huawei.
Arriving with 400G comes a new form factor, OSFP Octal Small Formfactor Pluggable. The OSFP has been created partly in mind to deliver future opportunities to expand to 800G, its larger size delivering the opportunity to handle more power through advanced internals and greater heat dissipation. At the time of writing only Arista offered direct plug in for OSFP transceivers, with other manufacturers likely to join soon. An OSFP adaptor is currently available.
QSFP-DD is the likely more common 400G option for optical transceivers in early years of use, and Pro Optix offers ranges in both OSFP and QSFP-DD. QSFP-DD does deliver more direct plug-in options with switch manufacturers.
Technical specialist Johannes Renfors overviewed the launch by saying “It is an interesting time for the optical world, it was not that long ago that 100G introduced itself and now we have 400G and new formfactors, both of which have started shipping quicker than expected to early adopters. The addition of PAM4 allows for higher data rates and will also drive technical development within 100G and 800G. It is early days for OSFP, but as an MSA approved formfactor, and the fact it is mapped for 800G in the future could see more switch manufacturers utilising the OSFP choice”
