SFP+ Fiber Optic Transceiver StarTech SFP10GBLRST — 10GBASE-LR, 10GbE SMF, LC, 10 km, 1310 nm, DDM

The StarTech SFP10GBLRST is a single-port SFP+ fiber optic transceiver engineered for 10GBASE-LR applications. Designed for deployment in compatible switches, routers and optical links, it provides 10 GbE connectivity over single-mode fiber with an LC duplex interface. The module operates at a 1310 nm wavelength and supports link lengths of up to 10 km, housed in a compact aluminium SFP+ form factor with digital diagnostics monitoring (DDM).

Advantages

This SFP+ transceiver is MSA-compliant and factory programmed to work with 10GBASE-LR equipment, offering interoperability and predictable behavior in multi-vendor environments. With typical power consumption below 1.3 W and a hot-swappable design, it enables energy-efficient operation and easy field replacement without interrupting network service. The metal housing provides mechanical durability and thermal dissipation suitable for rack-mounted networking hardware.

Suitable for

• 10 Gigabit Ethernet uplinks between switches and routers over single-mode fiber
• Long-distance campus, data center or metro connections up to 10 km
• Optical link upgrades or replacements in enterprise and service provider networks
• Environments requiring digital diagnostics for optical transceiver health monitoring

How to use

Verify that the target switch or router supports MSA-compliant SFP+ 10GBASE-LR modules. Power down the host only if recommended by the equipment vendor, otherwise insert the hot-swappable transceiver into the SFP+ cage until it seats firmly and the retention tab engages. Connect LC duplex single-mode fiber patch cables following correct polarity. Monitor the link status through the host device management interface and use the transceiver's DDM readings to confirm optical power, temperature and other diagnostic parameters.

Usage recommendations

Use factory-installed single-mode LC duplex patch cables rated for 1310 nm transmission and verify connector cleanliness before mating. For reliable long-distance links, follow bend-radius guidelines for single-mode fiber and allow for proper slack and strain relief. When troubleshooting link issues, compare DDM metrics against expected values and check both ends of the fiber path for loss or connector damage.
