Overview

The IDM OMP3500-180 Physically Isolated Gigabit Ethernet Optical Terminal, developed by Beijing Raytrans Digital Technology Co., Ltd., adopts a modular functional design and provides comprehensive service monitoring, access, protection, and network management capabilities.

The IDM OMP3500-180 Physically Isolated Gigabit Ethernet Optical Terminal is an ultra-wideband, multi-service optical transmission system centered on PDH, Ethernet, and PCM technologies, fully compliant with ITU-T standards. This equipment provides two 2.5G optical interfaces (A and B), up to 2 physically isolated wire-speed Gigabit Ethernet ports, 4 physically isolated wire-speed Fast Ethernet ports, and 16 E1 interfaces. It also supports multiple 64K services including FXS/FXO, V.35/V.24, hotline, and magneto telephone, and can accommodate video signals for convenient video surveillance system deployment. This equipment can be used to build point-to-point, point-to-multipoint chain, and ring transmission networks. The entire unit adopts a plug-in card structure, allowing configuration of different quantities and types of service cards and plug-in modules according to actual requirements, which not only reduces initial investment but also facilitates future expansion, upgrades, and maintenance.
