Description
TP-Link Omada SM5110LSA-10 — Single-Mode BiDi SFP Module, 10km
The TP-Link Omada SM5110LSA-10 is a single-mode bidirectional (BiDi) SFP fibre transceiver designed for use with Omada-compatible switches and networking equipment. Delivering reliable 1.25Gbps data transmission over distances up to 10km on a single strand of single-mode fibre, it's an efficient and cost-effective solution for enterprise campus networks, building-to-building links, and fibre infrastructure deployments across Australia.
Key Features
- Bidirectional (BiDi) design — uses a single fibre strand, reducing cabling costs
- 1.25Gbps data rate for reliable Gigabit Ethernet performance
- Up to 10km transmission distance over single-mode fibre (SMF)
- TX wavelength: 1310nm / RX wavelength: 1550nm
- LC simplex connector for easy, tool-free installation
- Hot-pluggable SFP form factor — no downtime required for installation
- Low power consumption for energy-efficient operation
- Compatible with Omada-series managed switches
- Compliant with IEEE 802.3ah and SFP MSA standards
Use Cases
-
Campus and enterprise networks: Extend Gigabit connectivity between buildings or floors using existing single-mode fibre infrastructure.
-
Building-to-building links: Ideal for connecting separate structures up to 10km apart without the need for additional fibre runs.
-
Cost-effective fibre upgrades: BiDi technology halves the fibre strand requirement, making it perfect for environments with limited fibre capacity.
-
Omada SDN deployments: Seamlessly integrates into TP-Link Omada Software-Defined Networking environments for centralised management.

Frequently Asked Questions
What does BiDi mean for an SFP module?
BiDi (bidirectional) SFP modules transmit and receive data over a single fibre strand using two different wavelengths — in this case, 1310nm for transmit and 1550nm for receive. This halves the number of fibre strands required compared to standard duplex SFP modules, making it ideal for environments with limited fibre capacity.
Does the SM5110LSA-10 need to be paired with another module?
Yes. BiDi SFP modules must be used in matched pairs. The SM5110LSA-10 (TX 1310nm / RX 1550nm) must be paired with a complementary module that has TX 1550nm / RX 1310nm at the other end of the fibre link.
Is this module compatible with non-Omada switches?
The SM5110LSA-10 is designed and tested for use with TP-Link Omada-series switches. Compatibility with third-party switches may vary. Check your switch's documentation or contact us before purchasing for non-Omada deployments.
What fibre cable do I need?
This module requires single-mode fibre (SMF) with an LC simplex connector. Ensure your fibre patch leads and infrastructure are rated for single-mode use.
Can I manage this module through Omada SDN?
The module itself does not require individual configuration, but when installed in an Omada-managed switch, the port and link status can be monitored through the Omada SDN Controller or Omada app.
