BH series PDH Optical Transceiver

The BH series PDH fiber optic multiplexer modulates 4/8/16*E1 into optical signals, then transmitsthe converted signal over a fiber optic cable for extended distances up to120km. 1+1 redundancy is available for optical interface to maximize uptime forthe key customers of carriers and ISPs.

The BH series provide reliable point-to-pointdata integration solutions at a reasonable price. It offers a cost-effective andquick deployment alternative for carriers concentrating TDM-based user serviceover optical fiber. Both standalone and central rack solution support remotemanagement and online upgrade.
