Edge|640™ Optical Circuit Switch

Calient Edge 640 OCS

CALIENT’s Edge|640™ Optical Circuit Switch is a variant of the S-Series product family that is purpose built for reconfiguring connectivity between network or device domains. Like the S‑Series Optical Circuit Switch, the Edge|640™ is transparent to data speed and is protocol agnostic. Consequently, it offers very high bandwidth and configuration flexibility as networks grow in speed from 40 Gbps, and 100 Gbps to 200 Gbps and beyond.

The Edge|640 offers 640 full-duplex ports and consists of two 320×320 switch cores. One core is used to create a half‑duplex connection from a device on one side to a device on the other side. The second switch core mirrors the first to create the other direction of a full‑duplex connection. This results in a much larger switch fabric that is ideally suited to applications at the network or domain edge.

Based on field-proven 3D Optical MEMS technology that CALIENT has deployed in more than 750,000 optical connections globally, the new Edge|640™ Optical Circuit Switch delivers high reliability, small form factor, low power consumption, low cost, and ease of use that allows the benefits of optical switching to be realized in a range of datacenter and service provider applications.

Applications

The Edge|640™ is appropriate for applications where any‑to‑any connectivity is not required across the entire group of client devices. This condition exists in many edge applications where devices at the edge of one network need to be cross‑connected to devices at the edge of another network, but there is no need for intra‑network connections. One example of this edge condition occurs between the edge router network and the transport network: northbound edge router ports must be cross-connected to transport resources, but there is no need to connect northbound router port to northbound router port. Another example is in LTE and 5G wireless optical transport networks where a pool of radio devices must be cross-connected to a pool of baseband devices, but there is no need to connect radio to radio or baseband unit to baseband unit.
