ATEN 2A-137G 1.25G SFP Transceiver Module 10KM server accessory

SKU CH-7GTD-2PH35 MPN 2A-137G

A hot-pluggable SFP transceiver delivers 1.25 Gigabit Ethernet over single-mode fiber up to 10 kilometers using a 1310 nm wavelength

  • TypeSFP (mini-GBIC)
  • 1 GbE connectivity over 10 km distance
  • Hot-pluggable SFP module enables quick installation
  • MSA compliant design ensures broad compatibility
  • 1310 nm wavelength optimised for single-mode fibre
  • Duplex 1000Base-X interface supports optical networking

Single-mode SFP transceiver

The ATEN 2A-137G is a hot-pluggable SFP module that delivers 1.25 Gigabit Ethernet over single-mode fibre. It uses a standard duplex connector at a nominal 1310 nm wavelength to reach distances up to 10 km. The unit is sold as a packaged pair for redundant or dual-link deployments.

Network and optical-network links

This module suits engineers building or extending 1000Base-X links across campus, metro or data-centre single-mode fibre runs. Buyers who need multi-mode fibre support, shorter reach optics, or higher line rates such as 10 GbE should look at different transceivers.

10 km reach at 1310 nm

The decisive specification is the 10 km transmission distance on single-mode fibre at 1310 nm. If the planned link exceeds this range, or if the installed cabling is multi-mode, this transceiver will not meet the requirement.

Questions about this item

How do I confirm the 2A-137G is working after inserting it into a 1000Base-X port?

The hot-pluggable module will show link and activity LEDs on the host port once a single-mode fiber patch cord is connected to the duplex connector and the far end is active.

What comes in the package and what must I source separately for the 2A-137G?

Two transceiver modules are included; single-mode fiber patch cords with duplex LC connectors are not included and must be purchased separately.

Which version of the 2A-137G should I choose for a 10 km single-mode link at 1.25 GbE?

This model operates at 1310 nm and is rated for 10 km on single-mode fiber, matching the stated 1.25 Gigabit Ethernet requirement.
