Refurbished Transition Networks SFP transceiver module, Cisco compatible, 1000Base-LX 6.2 miles

Transition Networks

Transition Networks TN-GLC-LH-SM SFP transceiver 1000Base-LX 6.2 miles Cisco compatible

SKU CH-87FM-K4TMR

Single-mode SFP transceiver for 1000Base-LX links up to 6.2 miles at 1.25 Gbps, Cisco compatible

  • Cisco-compatible SFP simplifies deployment in existing Cisco infrastructure
  • Single-mode 1000Base-LX optics extend links up to 6.2 miles
  • Hot-pluggable SFP form factor enables quick port upgrades
  • Gigabit Ethernet speeds up to 1.25 Gbps support high-throughput applications
  • Bidirectional serial-optical design provides reliable fiber-channel connectivity

Cisco Compatible SFP Transceiver

This Transition Networks SFP module delivers a 1000Base-LX interface for Gigabit Ethernet or fibre channel links. It operates at up to 1.25 Gbps over single-mode fibre with a reach of 6.2 miles. The hot-pluggable design fits any standard SFP port for immediate network integration.

Suited For Long-Haul Single-Mode Links

Network engineers extending campus or metro connections between switches and routers will find the 6.2 mile range appropriate. It is not intended for short-range multi-mode deployments where an SX optic would be more cost-effective. Buyers needing 10 Gbps or 25 Gbps throughput should select a different form factor.

Capacity And Distance Headroom

The transceiver comfortably handles full-duplex Gigabit traffic across the full 6.2 mile single-mode span. Headroom diminishes if the link budget is consumed by excessive splice loss or connector attenuation beyond typical specifications. It does not support speeds beyond 1.25 Gbps or reaches beyond the rated distance.

Questions about this item

Which switch or router SFP port will accept this module?

Any SFP port that supports 1000Base-LX optics will accept this transceiver.

Can I mix this single-mode module with existing multi-mode fiber links?

No, this module requires single-mode fiber; mixing fiber types will cause link failures.

How do I confirm the link is operating at 1.25 Gbps after installation?

Check the switch port status for a 1000 Mbps full-duplex connection and verify the receive power level is within the module's specified range.
