SFP+ Transceiver Module StarTech SFP10GSRXST — 10GBASE-SR, 10GbE MMF, LC, 850nm, 300m, DDM

The StarTech SFP+ Transceiver Module SFP10GSRXST is a compatible 10GBASE-SR optical module designed for 10 Gigabit Ethernet links over multimode fiber. It supports an 850 nm wavelength, LC connector, and a maximum reach of up to 300 m (984 ft). The module is hot-swappable and provides Digital Diagnostics Monitoring (DDM) for real-time status reporting, while typical power consumption is low (under approximately 1.2–1.3 W). It is supplied in a compact aluminium housing and is designed to work with Cisco-compatible switches and routers.

Advantages

This SFP+ transceiver delivers reliable 10GbE connectivity over multimode fiber with support for 10GBASE-SR networks and an LC connector for standard fibre links. Its hot-swappable design reduces downtime during upgrades or replacements, and DDM enables monitoring of operating parameters. The module’s compact aluminium housing and low power draw make it suitable for dense networking environments.

Suitable for

• 10 Gigabit Ethernet links over multimode fiber (MMF)
• Short-reach backbone and aggregation connections up to 300 m
• Installation in SFP+ ports of switches and routers compatible with Cisco SFP-10G-SR-X modules
• Data centre uplinks and campus network links

When it may not be suitable

The module is intended for multimode fiber and 10GBASE-SR applications; it is not suitable for single-mode fiber runs or long-distance links beyond the specified 300 m. It may be incompatible with network equipment that enforces vendor-locked transceiver checks if that equipment does not accept third-party compatible modules.

Key specifications

How to use

Insert the SFP+ module into a compatible SFP+ port on your switch or router until it clicks into place. Connect multimode fiber using LC patch cables, ensuring proper polarity and secure connectors. After installation the device should be detected by the host equipment and DDM can be used to monitor link status and transceiver parameters. The module supports hot-swapping, so it can be installed or removed while the host remains powered, provided the host equipment supports hot-swap procedures.

What to consider before purchase

• Confirm that your switch or router accepts third-party SFP+ modules or is compatible with Cisco SFP-10G-SR-X compatible transceivers.
• Ensure you will use multimode fiber (MMF) and LC connectors for the intended link and that the link length does not exceed 300 m.
• Verify transceiver power and cooling requirements for high-density installations.
• Check DDM support and management requirements for monitoring needs.

Usage recommendations

For reliable performance, use OM3/OM4 multimode fiber and high-quality LC patch cables, keep fiber connectors clean, and verify compatibility with your switch or router firmware. Monitor DDM readings during deployment to confirm acceptable optical power and temperature levels.
