HJ-iAN155 Optical Terminal is a multi-service SDH (Synchronous Digital Hierarchy) system at STM-1 level.Our Digital Hierarchy (DH) optical transmission system features dual STM-1 level optical interfaces for multiplexing and transmitting services such as E1 and Ethernet based on GFP encapsulation. It supports full-time slot cross functionality, with convenient and flexible uplink and downlink circuits, serving as both an uplink/downlink multiplexer and a terminal multiplexer. It can be used to establish point-to-point, chain, and ring networks.
The equipment is widely used in scenarios with high reliability requirements and comprehensive functional needs, such as telecommunications, mobile, unicom, power, public security, military, expressways, banking, aviation, and other specialized communication networks.
