Brief Introduction
The loopback module series are the most reliable products in the market to enable the quickest customers systems production and deployment. Software defined multiple power consumption may emulate the optical module power, and the embedded insertion loss characteristics emulates the real-world cabling for 100G/400G/800G Ethernet/Infiniband/FC. The built-in surge current mitigation technology mitigates the DUT risks from being damaged. The broad operating temperature range accommodates the enterprise, datacom and telecom applications. The loopback module may be used for ports testing, field deployment testing and equipment troubleshooting.

 | Optical transceivers port(LC) For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
