Product identity

This Ubiquiti Networks bidirectional SFP pair delivers 1 Gbps over single-mode fibre up to 3 km. Two modules are included, one with a blue latch transmitting at 1310 nm and one with a yellow latch transmitting at 1550 nm. They plug into LC simplex ports and draw 0.66 W each.

Ideal use and limits

Suits network builds that need a matched TX/RX pair for point-to-point links on SMF infrastructure. Not for buyers who require multi-mode fibre support, dual-fibre duplex connectors, or speeds beyond 1 Gbps.

Pre-install checks

Confirm your switch or router accepts SFP transceivers with LC simplex sockets and supports the 1310/1550 nm wavelength pairing. Verify the operating environment stays within 0 to 70 °C. Remember that fibre patch cables are not included and must be sourced separately.

Questions about this item

Which SFP port type on my switch accepts the LC simplex connector on this module?

The module fits any standard SFP cage that supports 1000Base-BiDi optics with an LC simplex receptacle.

Can I mix the blue-latch module with a legacy 1310 nm TX / 1550 nm RX transceiver from another vendor?

Only if the legacy unit uses the exact opposite wavelength pair — 1550 nm TX and 1310 nm RX — and is rated for 3 km single-mode fiber.

After installation, what LED pattern on the switch port confirms the bidirectional link is up at 1 Gbps?

A steady green or amber link light on the SFP port indicates a valid 1 Gbps connection; no light means the pair is mismatched or the fiber is faulty.
