HC-OE120-E8

HC-OE120-E8

Overview

HC-OE120-E8 is a fiber media transmission device for 8×E1. It provides one EOW, one RS-232C data and one Ethernet port added with AC or 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 offer two optical modules. Using different optical transceivers, the data can be transmit from 20Km up to 120Km.
