Ten small rectangular network transceiver modules with LC duplex ports, silver finish

Adafruit

Adafruit 10Pcs SFP Transceiver Module 1.25G LC Duplex 20km 1310nm 2 in 1 Accessories

SKU CH-A487-WQ53E

Ten 1.25 Gbps SFP transceivers with LC duplex connectors for single-mode fibre links up to 20 km at 1310 nm

  • 10-pack supplies 1.25 Gbps links for ten switch ports
  • 20 km reach on single-mode fibre with 1310 nm wavelength
  • Hot-swappable LC duplex design installs without powering down
  • 0–70 °C operating range suits data-centre environments
  • 1,000,000+ units deployed and 100 % aged for proven reliability

10-Pack SFP Transceiver for Long-Range Links

This pack supplies ten 1.25 Gigabit single-mode SFP modules with LC duplex connectors. They target network engineers extending fibre links between switches, routers, firewalls or media converters up to 20 kilometres. The 1310 nanometre wavelength suits campus or metro spans where multi-mode reach falls short.

Hot-Swap LC Duplex and Vendor Coding

Each module arrives pre-coded for immediate recognition on Mikrotik, Netgear, D-Link, Ubiquiti and TP-Link equipment, removing manual configuration steps. Hot-swappable LC duplex ports allow insertion or removal without powering down the chassis. The bundle avoids HP and Aruba platforms, where the vendor code is not accepted.

20 Kilometre Reach with 500 Metre Minimum

Single-mode optics rated for 20 kilometres require at least 500 metres of fibre; shorter runs overdrive the receiver and shorten module life. Operating temperature spans 0 to 70 degrees Celsius, covering standard data-centre environments. The 1.25 Gigabit line rate caps throughput below modern 10 Gigabit uplinks.

Questions about this item

Will the LC duplex connectors or fiber cables need periodic replacement in a 20 km single-mode link?

The modules use LC duplex connectors rated for repeated mating cycles; the single-mode fiber itself is passive and does not require scheduled replacement unless physically damaged.

What thermal limit is reached first when the transceivers run continuously at 70 °C ambient?

The specified operating range tops out at 70 °C; sustained operation at that temperature will hit the component thermal ceiling before any power or bandwidth limit is reached.

How much heat does a 10-pack generate when all modules run 1.25 Gbps all day?

Each SFP draws low power typical for 1.25 Gbps optics, so the combined heat output stays modest and is managed by the host switch’s airflow; no extra cooling is mandated.
