HC-OE120-2E1 optical terminal

Mini PDH optical terminals are standalone single E1/2× E1/V.35/Ethernet over fiber devices, with AC or DC power supplies built-in. The Mini PDH may be applied in point-to-point applications or they can be installed and linked to a centrally located MSAP or HC-COMM chassis. When the Mini PDH family are linked to the MSAP or installed in the chassis in card type, they can be managed by the management software HCView in the center office.  

HC-OE120-2E1 optical terminal

Overview

The HC-OE120-2E1 and the HC-OE120-E1 are fiber media transmission modems for 2 × E1/1×E1. Both AC and DC power supply are provided.

For the E1 port, there are two types of connector. The BNC type provides unbalanced 75Ω coaxial connections while the RJ45 type provides balanced 120Ω connections over twisted pair wiring.

For the optical port, it can provide multi-mode or single-mode optical transceivers. Using different optical transceivers, the data can be transmitted from 20Km up to 120Km.
