Speaking to the press, Vijay Kulkarni CEO of GL Communications said. “Optical Tap Repeaters provide multiple identical outputs for optical and electrical signals at OC-3 / STM-1, OC-12 / STM-4, OC-48 / STM-16, 1 GigE, and 2.5 GigE rates. The need for optical taps that cut the optical power by 30% or 50% are not needed, since the signals are repeated at full power”.

He further added, “T1 E1 Multiport Repeaters are used to generate multiple and identical T1 E1 outputs for each T1 E1 input, thereby increasing the number and range of transmission of T1 E1 signals.”

The sleek and standard design of T1 E1 Multiport repeaters allows multiple units to be easily placed in a mTOP™ 1U or 2U rack mount enclosure, providing different densities, stability, and security. For more details on mTOP™ rack-based platform, refer to Test Tools in Rack Based Platforms.
