8 Channel Analog Telephone to Fiber Converter With 2FE

This device provides 8 channels telephone and 2 Fast Ethernet interfaces, and it supports VLAN partitioning. It features a sound alarm function, as well as stability, reliability, low power consumption, high integration, and small size.

● Voice port supports FXO/FXS/2-wire audio/magnetic telephone interfaces. The FXO port is connected to the PBX, while the FXS port connects to the user’s telephone set;

● The FXO/FXS telephone interfaces support caller ID display, reverse polarity billing, and fax functionality;

● The telephone interface supports mutual dialing between two sites;

● The device has 2 100Mbps Ethernet ports with a bandwidth of line speed 100Mbps and supports full-duplex/half-duplex adaptive mode. The 2 Ethernet ports can be configured for logical isolation;

● The optical interface supports relay-free transmission distances of 2 to 120 kilometers;

● The telephone/network interfaces come with lightning protection, which can prevent lightning strikes up to the standards of GB/T17626.5(IEC61000-4-5), with a short-circuit current wave of 10/700μs and an open-circuit peak output voltage of 6KV;

● Multiple power mode options: AC220V, DC-48V / DC24V, etc.
