SKU CH-DDFV-ZRMEY

A single-mode SFP transceiver delivering 1.25 Gb/s over 20 km of 1310 nm fibre with DDM monitoring and wide vendor compatibility

  • Gigabit Ethernet link at 1.25 Gb/s over single-mode fiber up to 20 km
  • Works with Cisco GLC-LH-SMD, Meraki, Ubiquiti UniFi, Mikrotik, Intel, Netgear, D-Link and more
  • Hot-swappable SFP MSA module with digital diagnostic monitoring for real-time link status
  • Low power draw under 1.05 W with built-in ESD protection
  • Individually tested before packing to ensure reliable operation

1.25G Single Mode SFP Module

This 1.25G Single Mode SFP LC module delivers 1000Base-LX/LH Gigabit Ethernet connectivity over single-mode fibre. It operates at a 1310nm wavelength with a reach of up to 20km (12.4 mile) on OS1/OS2/OS3 cable. The duplex LC interface supports hot-swappable installation and includes Digital Diagnostic Monitoring for real-time link parameter visibility. It complies with SFP MSA and IEEE 802.3z standards.

Suits Cisco Meraki Ubiquiti Mikrotik networks

This transceiver suits network administrators deploying or maintaining Gigabit links on Cisco GLC-LH-SMD, Meraki MA-SFP-1GB-LX10, Ubiquiti UF-SM-1G, Mikrotik, Intel, Netgear AGM732F, D-Link or TP-Link equipment. Its broad compatibility simplifies spares management across mixed-vendor environments. Buyers who need multi-mode fibre, longer single-mode distances, or higher data rates such as 10G should look at different modules.

20km reach at 1310nm decides fit

The single specification that determines suitability is the 20km reach at 1310nm on single-mode fibre. Verify that your link distance and fibre type match these parameters before purchase. Power consumption stays below 1.05 watt, and each unit is individually tested prior to packing.
