Different from the 40G Ethernet, 50G Ethernet initial limited deployment as proprietary 2x25G or 1x50G. It could provide faster bandwidth to extend the existing data center network. Making them ideal for a range of applications including data center equipment, test and measurement equipment and wireless infrastructure devices.
SFP56 optimized construction minimizes insertion loss and cross talk, and the solutions are backward compatible with existing QSFP and SFP connectors and cages for easy upgrades. Paired with QSFP28 and SFP28 connectors and cages, the SFP56 cable assemblies offer broad solution for connectivity between devices.
The 100G serial transceiver in the popular QSFP28 form factor for inter-data centre, transport and router applications with 2km reaches.
SFP56 high speed cable assemblies comply with Ethernet 802.3cd and support 56G PAM-4 applications. 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
Four of these FR or DR modules will be able to be used in a fan-out configuration with an IEEE standard 400G DR4 module, thus providing both 100G point-to-point and 100G-to-400G fan-out connectivity at 100G per lane.
These modules represent the next key step in the highly popular SFP+ family of optical modules that have become ubiquitous in worldwide enterprise, data centre and service provider networks. Primary applications for these products include server-to-switch and switch-to-switch 50G Ethernet connections, and future 5G wireless applications.
Leveraging in-house vertically integrated optics and IC’s, these modules support interoperability with previous generations of 25G SFP28 and 10G SFP+ optical transceivers. Both modules comply with the corresponding 50GBASE-R specifications as defined in the IEEE standards and offer 50G PAM4 electrical and optical interfaces.. This will enable us to deliver unprecedented bandwidth to customers in form factors that are backwards compatible with industry established footprints
SFP56 cable assembly portfolio draws upon vast expertise in high-performance connectivity solutions to enable 100 and 200 gigabit speeds for next generation communications equipment.
