New Calient optical circuit switch developed in response to demand for growing device counts

Calient Technologies launched, at the recent OFC 2018 event, its Edge|640, a new optical circuit switch with 640 fibre-optic cross connections – up to twice the capacity of the company's existing S320 OCS.

The Edge|640 was developed for data centre, telecommunication and test laboratory applications in response to growing device counts and the need – due to network virtualisation – for increased connectivity. Key applications include wireless network radio-to-baseband units; test lab automation shared test resources and data centre GPU, FPGA and storage compute clusters.

Calient and Spirent team for all-optical test lab automation

Optical switch specialist Calient announced that Spirent Communications has completed integration of its S Series optical circuit switch with Spirent’s Velocity test bed orchestration software.

Spirent has developed a software driver that allows Velocity to control Calient’s S320 and S160 optical circuit switches to provide Layer-1 optical topology reconfiguration in network equipment test labs. This allows network test laboratories to build a fully automated “fibre-once” laboratory infrastructure.

Calient pitches switches for data centre virtualisation

The trend towards virtualisation could lead to an expanded role for optical switches inside data centres, according to Calient Technologies.

The optical circuit switch developer is proposing a new data centre architecture that would allow data centre operators use server and storage resources more efficiently – if they are prepared to buy some optical switches.
