答ZXONU是ZXA10光纤综合接入网系统中光网络单元(ONU)的统称。它分为室内型和室外型两大类,共6种型号。室内型光网络单元是将电路板、单体整流器、环境和电源监控部件、蓄电池、配线架做在一体化机架内的光网络单元。室外型光网络单元是在室内型光网络单元的基础上配置了半导体空调,采用集中监控系统自动控制制冷和制热的光网络单元。这两种光网络单元都有以下特点:
A ZXONU is a general term for Optical Network Units (ONUs) in the ZXA10 Optical Access Network. It is divided into indoor and outdoor two categories, a total of 6 models. Indoor optical network unit is the circuit board, single rectifier, environmental and power monitoring components, batteries, patch panels in the integrated rack within the optical network unit. Outdoor optical network unit is based on the indoor optical network unit equipped with semiconductor air conditioners, centralized monitoring system that automatically controls the cooling and heating of the optical network unit. Both optical network units have the following features:
