IDM GP2000|PDH·📅UpdatedMay 12, 2026·✍️管理员

The IDM GP2000-4E1 PDH Optical Multiplexer provides two SFP optical interfaces, five E1 circuits, and two 1000M line-speed Ethernet interfaces in a single unit. It offers an SNMP network management interface, comprehensive alarm and monitoring functions, high integration, low power consumption, stable performance, and ease of use. The GP2000 can interconnect with the GP2400 via optical ports, with dual SFP optical ports providing mutual backup. It is widely used in private networks such as public security, power, railway, and mining, as well as public networks operated by China Mobile, China Unicom, and China Telecom.
