Telecom inverter is an electronic circuit that converts direct current to alternating current. This inverter provides economical AC power for all types of network needs. It features a built in utility bypass, and can be cascaded to be redundant. It is built for long mean time between failures. It is used in telecom power plants, electric utilities & substations, base station power, industrial controls and emergency power backup.

Telecom transformers are used in applications, which require high bandwidths and fast switching speeds. The transformer isolates the signal between primary and secondary grounds. The different types of telecom transformers are DSL transformers, xDSL transformers, T1 transformers, E1 transformers, ISDN transformers, LAN transformers, WAN transformers and ATM transformers. Performance specifications for telecom transformers include operating frequency range, direct current resistance, insertion loss, three-decibel bandwidth, operating temperature and maximum dimension.
