HC-OE120-E8T

HC-OE120-E8T  

Overview

HC-OE120-E8T is a fiber media transmission device for 8×E1 and two Fast Ethernet. It provides, one RS-232Cdata added with AC or DC power supply.

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

For the Fast Ethernet, it provides two Fast Ethernet ports with RJ45 connector.

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.
