Stand-alone Fast Ethernet media converter 100Base-TX to 100Base-FX 6

Transition Networks

Transition Networks E100BTXFX06SMLCNA switch module 100Base-TX to 100Base-FX 6

SKU CH-R6MN-EJF91 MPN E100BTXFX06SMLCNA

Stand-alone media converter links 100Base-TX copper to 100Base-FX fiber at line speed with auto-negotiation and automatic link restoration

  • Integrates fiber into 100Base-TX copper networks using 100Base-FX media conversion
  • Low-latency Layer 1 operation passes data at line speed for time-sensitive applications
  • Auto-negotiation and Auto-MDI/MDIX simplify installation without manual port configuration
  • Active link pass-through with Far-End-Fault detection maintains link awareness across the fiber segment
  • Automatic link restoration and pause support preserve connectivity during transient network events

Stand-alone Fast Ethernet Media Converter

The E100BTXFX06SMLCNA is a stand-alone media converter that bridges 100Base-TX copper ports to 100Base-FX fiber ports. It allows network administrators to integrate fiber optic cabling into existing 100Base-TX copper environments. The unit operates at the physical layer for transparent data passage.

100 Mbps capacity and latency headroom

Running at line speed, the converter handles 100 Mbps Fast Ethernet traffic with minimal latency, making it suitable for applications where timing is critical. It does not support Gigabit or higher speeds, so bandwidth tops out at 100 Mbps. Auto-negotiation and Auto-MDI/MDIX simplify copper-side connections.

Layer 1 physical-layer operation

Because the device functions strictly at Layer 1, it passes frames without buffering or switching logic, preserving timing for latency-sensitive links. Buyers needing managed switching features, VLAN support, or routing capabilities should look elsewhere. This converter is built for simple, transparent media conversion only.

Questions about this item

Will this converter work with my existing 100Base-TX copper switches and NICs?

Yes, it provides a direct interface between 100Base-TX copper ports and 100Base-FX fiber ports, integrating fiber into your current 100 Mbps copper environment.

How can I confirm the link is healthy after connecting both ends?

Active Link Pass Through and Far-End Fault (FEF) signal a loss of link on the fiber side back to the copper side, so both link LEDs will show the true end-to-end status.

Does the box include the fiber patch cables and copper patch cords I need?

The unit itself is a stand-alone media converter; fiber patch cables with LC connectors and Cat5e or better copper patch cords must be sourced separately.
