Seeking to address the need for testing new technology defined by the IEEE Power Engineering Society, Sunrise Telecom Inc. introduced the Sunset MTT-45 module for IEEE's C37.94 standard. This new module aims to make the SunSet MTT platform an all-in-one test solution for xDSL, SONET/SDH, E1/T1, Ethernet, ISDN, VoIP, data communications, optical fiber and copper wire testing.

The IEEE C37.94 standard defines an Nx64Kbps multimode optical fiber interface between teleprotection and digital multiplexer equipment, up to 2km. The product is designed to assist technicians as they turn up a new network or work to isolate problems on both sides (teleprotection and multiplexer) of an existing network using this technology.

The new module's bit error rate testing capabilities allow engineers to check the performance of IEEE C37.94 links prior to turning up the circuits. The unit's alarm monitoring and optical power measurement lets technicians verify connectivity and power levels for the optic fibers. Using this system, engineers can also measure propagation delaythe round-trip time of a digital signal on the C37.94 teleprotection communication linewhich is a critical element of the overall time required for a protection system to automatically and successfully respond to failures and prevent outages in a power transmission network.

The IEEE standards committee defined the C37.94 standard to allow interoperability between different vendors of teleprotection and multiplexer equipment. Teleprotection equipment is used to quickly isolate faults in power transmission systems and is crucial for preventing damage to the network and power outages (blackouts). Teleprotection is being deployed on communication links residing in harsh high-voltage substation environments. The optical data link in these systems that replaces existing electrical interfaces provides immunity to intra-station EMI and reduces data errors while transmitting data at speeds up to 12 x 64Kbps.
