Data & Ethernet Multiplexer (4-12 Ch.)

Rollover or Touch for Expanded View. Scroll to Zoom.


Combine Ethernet & Serial Data over a single mode and multimode fiber optic network with the Model TC8530 Ethernet & Data Fiber Optic Multiplexer.

The Model TC8530 Ethernet and Serial Data multiplexer multiplexes one 10/100M Ethernet and four channels of RS-232, RS-422, TTL or Dry Contact interfaces over single mode and multimode fiber. A "bi-directional 1-fiber" option doubles existing fiber optic cable usage.

  • Multiplexes 10/100 Ethernet, RS-232, RS-422, TTL, Dry Contact
  • Network Management (Web, Telnet)
  • One Fiber Bi-Directional Optic Communication Option
  • Multimode or Single Mode (1300/1550nm)
  • Power Redundancy, Optical Redundancy Optional
  • 12VDC, Optional 24VDC, -48VDC, 125VDC or 115/230VAC
  • Industrial Hardened (optional)
  • Hi-Temp2 Version Exceeds NEMA & Caltrans Traffic Control Specs


Typical applications include extending SDH/SONET backbones and adding Ethernet and Serial service to existing fiber optic links. Service Providers use the TC8530 as an efficient, cost effective method to provide their customers with Ethernet and Serial connections. The one fiber bi-directional optic option can double usage of existing fiber optic cable plants.
