BlueOptics SFP28 AOC Cable LTF8507-PC07 — 25GBASE-SR4 Active Optical Cable, 7 m

BlueOptics SFP28 AOC Cable LTF8507-PC07 is an active optical cable designed for short-reach data center and server interconnects. The 7 m cable uses SFP28 form-factor transceivers and supports 25GBASE-SR4 operation by carrying four parallel 25 Gbps lanes. It provides a low-power, plug-and-play optical link for 25 Gigabit Ethernet and compatible InfiniBand environments where fiber connectivity is required between switches, servers or optical modules.

Advantages

This active optical cable offers a compact, integrated solution that eliminates separate transceivers and fiber patch cords, reducing cabling complexity in dense racks. The AOC design delivers electrical-to-optical conversion within the assembly, enabling lower power consumption than many discrete optics plus patch cabling arrangements. Plug-and-play compatibility with SFP28 ports simplifies installation, while the multimode SR4 specification supports high aggregate throughput over a 7 m fiber link.

Suitable for

• Short-reach 25 Gigabit Ethernet links inside data centers
• Server-to-switch and switch-to-switch interconnects up to 7 m
• High-speed InfiniBand connections that accept SFP28 AOC modules
• Environments requiring low-power, low-latency optical links

When it may not be suitable

This cable follows the 25GBASE-SR4 multimode SR specification and is intended for short-reach links; it is not suitable for long-reach singlemode fiber runs or installations that require distances beyond the 7 m cable length. It also requires equipment with SFP28 ports that support SR4 or compatible AOC modules and will not function with devices limited to other form factors or incompatible transceiver types.

Key specifications

• Form factor: SFP28 active optical cable
• Data rate: Four lanes of 25 Gbps (aggregate 100 Gbps in SR4 topology) or 25G per lane usage depending on host support
• Standard: 25GBASE-SR4 compatible multimode optical link
• Length: 7 m
• Connector type: SFP28 plug-to-plug AOC
• Power: Low-power AOC assembly (integrated optics and electrical interface)
• Typical applications: Short-reach Ethernet and InfiniBand interconnects within racks or between adjacent racks

How to use

Install the cable by inserting each SFP28 plug into the corresponding SFP28 port on your switches or servers until the latch clicks. Ensure both devices support the required SR4 or SFP28 AOC operation. No separate transceivers or fiber patch cords are needed. After insertion, verify link status via the host equipment management interface and check that the negotiated speed matches expected 25G/100G operation. For best signal integrity, avoid sharp bends and maintain the cable within its recommended bend radius.

What to consider before purchase

• Verify that your devices have SFP28 ports and support SR4 or compatible AOC modules
• Confirm the 7 m length meets your rack or row cabling distance requirements
• Ensure multimode SR4 connectivity is acceptable for your network topology (not suitable for long singlemode links)
• Check equipment firmware and compatibility lists if your vendor enforces optical module compatibility

Usage recommendations

For reliable operation, route the cable to avoid excessive bending, secure it to prevent strain on the SFP28 connectors, and verify link status after installation. Use within data center rack or short inter-rack spans where a 7 m multimode optical link is appropriate.
