MM04 - 4-Port E1 Fiber Optic Media Multiplexer
The MM04 product line is a 4 port E1 or T1 multiplexer/demultiplexer that transmits over a fiber optic link. The products are standalone (1U), 19" rack mountable (half-size devices). The optical fiber interface is available in a number of standard fiber connections and has optional redundant optical connections. The chassis is available with universal AC power supply (100-240v) or DC power supply (36-60v) and and in option of redundant power supply.
MM04 devices support four (4) link interfaces and are available for E1 or T1 configurations with connections for RJ-48 (E1/T1 balanced). In long haul mode the interfaces possess usable receive sensitivity of 0 dB to -43 dB for E1 and 0 dB to -36 dB for T1 which allow the device to operate with 0.63 mm (22AWG) cables at distances up to 2.5 km (E1) and 6000 feet (T1).
Each E1/T1 port is designed to meet regulatory compliant solutions such as for circuit protection against surges and AC lightning, which is essential for long haul E1/T1 lines.
A robust frame-acquisition and frame holding algorithm minimizes frame slippage and resynchronization.
