Ubiquiti Uplink Cable 0.3 m - SFP28 to SFP28
0.3 mCopper direct attachSFP28 to SFP281 / 10 / 25 Gbps
The Ubiquiti Uplink Cable, SKU UACC-Uplink-SFP28-0.3M, is one 0.3 m white copper direct attach cable with two integrated SFP28 plugs. It supports 1, 10 and 25 Gbps data rates when the connected devices and ports support the intended link speed. Auto link optimisation is advertised for UniFi-to-UniFi interconnects.
Best For: For connecting nearby compatible network devices through SFP28, SFP+ or SFP interfaces, where a 0.3 m cable reach is suitable and the ports support the required link speed.
Before you order: Check that both devices support the intended link speed and that the routed path suits the 0.3 m length and 23 mm minimum bend radius. A 1G SFP port does not become 25G. Auto link optimisation is stated for UniFi-to-UniFi interconnects; universal third-party compatibility is not established. This is not an RJ45, LC/SC fibre, USB or QSFP cable, and it is not a standalone transceiver.
What's in the Box
- One Ubiquiti Uplink Cable, 0.3 m, with two permanently integrated SFP28 plugs.
What It Means in Practice
- The 0.3 m length suits nearby compatible equipment; check the actual cable route before choosing it.
- The cable supports 1, 10 and 25 Gbps, but the connected devices and ports must support the intended rate.
- Allow for its 23 mm minimum bend radius when routing the cable.
- Both connector ends are integrated, so separate transceiver modules are not needed to complete this cable.
What Will Not Work
- The cable is 0.3 m long; no extension cable is included or promised.
- A 1G SFP port does not support a 25G link merely by using this cable; the end devices and ports must support the intended speed.
- Auto link optimisation is advertised for UniFi-to-UniFi interconnects; universal third-party compatibility is not established.
- The integrated ends are SFP28; this is not an RJ45, LC/SC fibre, USB or QSFP cable, nor a standalone optical transceiver.
Key Features
Integrated SFP28 ends
Both SFP28 plugs are part of the cable, avoiding a need for separate transceiver modules to complete it.
1 / 10 / 25 Gbps support
Supports these link rates when the connected devices and ports are capable of the intended speed.
Short 0.3 m copper cable
A compact reach for nearby compatible equipment; check the routed path and minimum bend radius.
UniFi auto link optimisation
Speed and stability optimisation is advertised when interconnecting UniFi devices.

Frequently Asked Questions
Does this cable include both connectors?
Yes. It is one complete cable with two permanently integrated SFP28 plugs; separate transceiver modules are not required to complete the cable.
Will it provide a 25 Gbps link on any SFP port?
No. The connected devices and ports must support the intended link speed. A 1G SFP port does not become 25G with this cable.
Is this the fibre version or an RJ45 cable?
No. The exact 0.3 m SKU is copper with SFP28-to-SFP28 ends. It is not an RJ45 cable or an LC/SC fibre patch cable.
Does auto link optimisation apply to all brands?
The stated speed and stability optimisation is for UniFi-to-UniFi interconnects; universal third-party compatibility is not established.
Singular Expert Insight
This is a single short copper direct attach cable with both SFP28 ends integrated, so separate transceiver modules are not required to complete the cable. Its supported rates cover 1, 10 and 25 Gbps links, subject to endpoint capability.
Buyer’s Guide
✓ Buy it if For connecting nearby compatible network devices through SFP28, SFP+ or SFP interfaces, where a 0.3 m cable reach is suitable and the ports support the required link speed.
✕ Skip it if Check that both devices support the intended link speed and that the routed path suits the 0.3 m length and 23 mm minimum bend radius. A 1G SFP port does not become 25G. Auto link optimisation is stated for UniFi-to-UniFi interconnects; universal third-party compatibility is not established. This is not an RJ45, LC/SC fibre, USB or QSFP cable, and it is not a standalone transceiver.
