The HJ-iAN155 optical terminal is an STM-1 level multi-service SDH (Synchronous Digital Hierarchy) optical transmission system. It features two STM-1 level group optical ports, enabling the multiplexing and transmission of services such as E1 and Ethernet based on GFP encapsulation. It supports full time-slot cross-connect functionality, with flexible and convenient upstream and downstream circuits, and can serve as an upstream/downstream circuit multiplexer or terminal multiplexer to form point-to-point, chain, and ring networks.
The equipment is widely used in scenarios requiring high reliability and comprehensive functionality, such as dedicated communication networks for telecommunications, mobile, Unicom, power, public security, military, highways, banking, aviation, and more.
