Features

The TC8518 T1/E1 Data/Voice & Ethernet Fiber Optic Multiplexer multiplexes 4/8/16 channels of T1/E1 and 3 Ethernet ports on single mode (1300/1550nm) or multimode (1300nm) fiber.

The TC8518 T1/E1 is most often used for connecting T1/E1 signals from Cell Towers to Central Offices, multiplexing T1/E1 links between PBX’s, and adding Ethernet, Analog, Data or Telephone service to existing T1 or E1 fiber optic links.

  • Multiplexes Up to 24 T1 or 20 E1 and 3 Ethernet Ports Over Fiber
  • Optional Voice (up to 8 channels FXS/FXO or 4 channels 2 Wire/4 Wire Analog) or Data (up to 8 channels RS-232/RS-422/RS-485)
  • Optical and Power Redundancy Standard
  • Key Features: Statistics Monitoring (T1/E1, Ethernet, Optics), Ethernet Rate Limiting, Remote Firmware Upgrade, Network Time Server (NTS), Temperature Monitoring and Loop Up/Down Codes
  • Management (Web, SNMP, Telnet,Console)
  • FXS/FXO Ports Support Modems & Faxes
  • High Temp (-20°C to +70°C) and Extreme Temp (-40°C to +80°C) Optional
  • Multimode or (1300nm) or Singlemode Optics (1300/1550nm)
  • 90-260VAC Hot Swappable Power Standard Optional Power: 12VDC, 24VDC, -48VDC, 125VDC

Applications

Typical applications include connecting T1/E1 signals from Cell Towers to Central Offices, multiplexing T1/E1 links between PBX’s, and adding Ethernet, Analog, Data or Telephone service to existing T1 or E1 fiber optic links.

Service Providers use the TC8518 as an efficient, cost effective method to provide their customers with Ethernet (100Mbps Total Bandwidth) for data and T1/E1 for voice. Analog channels can be used for radio applications.

The one fiber, bi-directional optic option doubles existing fiber optic cable capacity.
