Rollover or Touch for Expanded View. Scroll to Zoom.


Intended as a point-to-point link for high speed synchronous data devices, the TC1504 Fiber Modem is an economical fiber optic network connectivity solution.

Transparent to the data and DCE/DTE switchable, the TC1504 combines external clocking and data into an optical composite signal for transmission between local and remote units. It supports all types and sizes of multimode (850nm/1300nm) or single mode (1300/1500nm) fiber optic cable. An extended temperature version (-20°C to 70°C) is optional.

  • Sync Data Rates up to 2.048 Mbps
  • Distances up to 80km
  • Multimode or Single Mode (850/1300/1550nm)
  • DTE/DCE Selectable
  • Six Diagnostic LEDs
  • Slave Clock
  • Local & Remote Loopback Functions
  • Hardened Temperature Version (optional)
