I. Overview

The IDM GP2400-8E1-30 Ultra-Broadband Integrated Service Optical Multiplexer utilizes 2.5G optical fiber transmission bandwidth (G.703 standard) with PCM30/31 framing, providing dual-fiber mutual backup. It directly offers telephone service interfaces (30 channels of FXO, FXS, or Magneto), 4 groups of physically isolated wire-speed 100M Ethernet (400M total), 2 groups of physically isolated wire-speed 1000M Ethernet (2000M total), E1 (1-8 E1 channels), HDMI high-definition video transmission, and various other user interfaces. Meanwhile, the equipment features easy installation and is suitable for a wide range of application environments.
Provides dual-fiber mutual backup, and can also be combined with other devices to form multiple physically isolated Ethernet chain networks Telephone Optical Terminal, ring networks Telephone Optical Terminal, and point-to-multipoint star networks Telephone Optical Terminal.
