HC-OE120-8E1

HC-OE120-8E1 optical terminal 

Overview

The HC-OE120-8E1 is a fiber media transmission device for 8 × E1/G.703. It provides one EOW and one RS-232C data port added with both AC and DC power supply.

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

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.
