Ethernet Over SDH (Ethernet over STM-1)

Product Overview

Orion’s VCL-Ethernet-over-SDH provides a simple, cost effective and compact solution to convert 10/100BaseT data interface on the user side and transport Ethernet traffic over a STM-1 SDH link and reconstruct the data back to ethernet frame format, at remote end. The converter is an effective method for converting and transporting 10/100BaseT ethernet data over an STM-1 (SDH) link.
