室外型四路输出光接收机

描述

The 4 Port CATV Outdoor Optical Receiver is designed to deliver stable, high-level RF signal distribution in FTTH, FTTB, HFC, community broadband, and village CATV networks. Featuring four RF outputs, automatic gain control (AGC), and an IP65 waterproof aluminum housing, this 4 output receiver ensures reliable operation even in harsh outdoor environments while maintaining consistent signal quality for multiple subscribers.

The rugged outdoor design makes it an ideal solution for multi-dwelling buildings, residential communities, rural broadband projects, and locations where power resources are limited. Support for ONU or EOC integration, Outdoor Optical Receiver enables efficient Triple Play service delivery,including CATV, broadband Internet, and IPTV. The combination of high output capability, lightning protection, network management support, and flexible output configuration makes this optical receiver a dependable choice for modern CATV distribution networks.

1. Outdoor Optical Receiver Applications

The four-way output optical receiver is a field rain-proof receiver. It is suitable for users with concentrated buildings or communities or villages. It is suitable for multi-port high-level output distribution network. It is suitablefor areas where power is not convenient, single unit with multiple users. Can be used with ONU or EOC to achieve triple play.

四路输出光接收器前级采用全砷化镓MMIC放大，后级为砷化镓模块放大器。 衰减、均衡可调，施工非常方便。 用户还可以根据实际需求选择更有针对性的优质模块。 优化的电路设计使该机达到了较高的性能指标，是构建CATV网络的理想机型。
