Overview

  MXT-OTR-8601 field independent four-output optical node is bi-directional optical transmission equipment in CATV HFC network to realize head-end signal’s download and user signal’s return in one optical link. The function modular structure will take great convenience to usage, bi-directional network improvement and upgrade, as well as opening the value-added service. This designing supports IP phone, Internet, interactive data multiple service. It is broadband telecommunication optical node integrated with TV signal and data signal transmission.

  MXT-OTR-8601 optical node featured with small volume, great function, beautiful appearance, perfect performance index, high output level and network management function.


Features

Modular structure design, it can transmit CATV signal and open multiple data service, matched five

function modules at most, herein, one optical receiver module is necessary, others are optional. Two optical receiver modules can realize backup function; two return optical transmitter modules can realize four-output combination return; SNMP can monitor equipment’s multiple operation status.

Optional status monitor is compatible with SCTE HMS standard.

Four-output high level output can be up to 112dBuV, to ensure perfect optical link index in high level

output.  

equipped-in bi-directional filter, high-low pass dividing frequency is optional.

Optical control AGC function design, to make output level keep stable when input optical power

-6/-4~+2dBm.

Four digit highlight LED digital tube displays equipment’s each operation parameter

real-timely(optical power, output level, inner temperature, voltage).

Delicate die-casting aluminum alloy housing, dacromet treatment, good heat dissipation, waterproof, radiation protection, and anti-interference.

Hot plug type optical receiver module, return optical transmitter module and SNMP is convenient to upgrade for user.

High reliability switch power supply, high conversion efficiency, wide voltage range, single/double

power supply optional, easy to use.

Each channel can feed, with sole 60VAC feed port.

Each channel with forward path output level and return path input level -20dBm monitoring port.

Each channel forward path output level, return path input level is adjustable.
