10GBASE-SR SFP+ module

The STARTECH SFP10GSRXST is a hot-pluggable SFP+ transceiver built for 10 Gigabit Ethernet links over multimode fibre. It targets network engineers and system integrators who need a Cisco SFP-10G-SR-X compatible optic for 10GbE uplinks or server connections.

LC duplex multimode fit

The module presents a single LC duplex female port and operates at an 850 nm wavelength on OM3 or OM4 multimode fibre. It slots into any standard SFP+ cage that accepts IEEE 802.3ae 10GBASE-SR optics, freeing a copper port while extending reach to 300 m without a media converter.

0 °C to 70 °C sustained operation

Rated for continuous use between 0 °C and 70 °C, the transceiver maintains the 10 Gbps line rate across the full temperature range rather than throttling after a short burst. Storage tolerance spans -40 °C to 85 °C, and humidity tolerance covers 5 % to 95 % RH non-condensing.

Highlights

  • Delivers 10 Gbps Ethernet over multimode fibre
  • Reaches 300 m on 850 nm multimode cable
  • Hot-pluggable SFP+ module for zero-downtime swaps
  • 100 % Cisco SFP-10G-SR-X compatible
  • Operates 0 °C to 70 °C for rack environments

Questions about this item

How far can the 850nm 10GBASE-SR signal reach on multimode fibre before it becomes the limiting factor?

The module supports up to 300 m (984 ft) over multimode fibre at 850 nm.

What heat load should I plan for when the SFP+ runs continuously at 0–70 °C ambient?

Operating temperature is rated 0 °C to 70 °C (32 °F to 158 °F) with 5–95 % RH; the hot-pluggable SFP+ design draws minimal power and produces low noise.

Which host-side interface must my switch or router provide to accept this transceiver?

It requires an SFP+ cage with an LC duplex female fibre port.
