10-Gigabit SFP+ Transceiver 10km

This Juniper-compatible SFP+ transceiver provides 10 Gigabit Ethernet connectivity over single-mode fibre up to 10 kilometres. It is designed for network engineers and data-centre operators who need long-range links between switches or routers. The module carries part number 740-021309 and matches the EX-SFP-10GE-LR-A specification.

Sustained long-range operation

The transceiver is built for continuous 10 Gbps transmission across 10 km of single-mode fibre without the signal degradation seen in shorter-reach optics. Its long-range laser maintains stable optical power and receiver sensitivity during extended traffic loads, making it suitable for backbone links that run at full line rate around the clock.

Pre-deployment checklist

Verify that your switch or router accepts Juniper-coded SFP+ modules and that the target ports support 10GBASE-LR. Confirm the patch cables are single-mode with LC duplex connectors polished to UPC or APC standards. Ensure the link budget matches the 10 km distance including any patch-panel loss.

Questions about this item

How much heat does the 10-Gigabit SFP transceiver generate when running continuously?

The module operates within standard SFP+ thermal limits for long-range optics, so typical chassis airflow is sufficient for all-day operation.

What host equipment must I already have to use this 740-021309 transceiver?

You need a switch or router with an SFP+ cage that supports 10GBASE-LR optics and single-mode fibre cabling with LC connectors.

Will this 10km LR transceiver link reliably with older 10-Gigabit switches from other vendors?

Yes, it follows the 10GBASE-LR multi-source agreement, so it interoperates with any compliant 10GBASE-LR port regardless of switch age.
