Juniper 10GBASE-SR SFP+ Transceiver — 300m Multi-Mode Fiber

The Juniper SFPP-10G-SR-C is a 10GBASE-SR SFP+ optical transceiver delivering 10GbE over multi-mode fiber up to 300m at 850nm via duplex LC connector — Juniper-coded for plug-and-play compatibility across Juniper EX, QFX, MX, PTX, and SRX platforms requiring standard 10G MMF connectivity for data center and campus fiber deployments.

Key Features

• 10GBASE-SR SFP+ for 300m 10GbE over OM3 multi-mode fiber at 850nm
• Duplex LC connector for standard MMF patch panel and structured cabling compatibility
• Juniper-coded (SFPP-10G-SR-C) for recognized, warning-free operation on Juniper platforms
• DDM/DOM support for real-time optical power and health monitoring via Junos OS
• Low-power VCSEL laser for energy-efficient 10G MMF deployments

• Not compatible with single-mode fiber (use SFPP-10G-LR for SMF applications)

Frequently Asked Questions

What is the maximum distance of the SFPP-10G-SR-C on OM4 fiber?

On OM4 (50µm, 4700 MHz·km bandwidth) fiber, 10GBASE-SR supports up to 400m — an improvement over the 300m limit on OM3 fiber. For data center deployments with long cross-floor or inter-building MMF runs, OM4 provides additional reach margin at 10G.

Can the SFPP-10G-SR-C be used in a 25GbE SFP28 port?

No — SFP+ and SFP28 are physically compatible form factors, but a 10GBASE-SR SFP+ will operate at 10GbE in an SFP28 port, not 25GbE. For 25GbE MMF connectivity, use the SFP-25G-SR-C instead.

Does the SFPP-10G-SR-C support Digital Diagnostics Monitoring?

Yes — DDM/DOM is supported, enabling Junos OS to report TX/RX optical power, temperature, voltage, and laser bias current in real time. DDM data is accessible via Junos CLI (show interfaces diagnostics optics) and SNMP for proactive transceiver health monitoring.

The Juniper SFPP-10G-SR-C delivers Juniper-coded 10GBASE-SR connectivity over OM3/OM4 multi-mode fiber with DDM monitoring and broad platform compatibility — providing the standard 10G MMF transceiver for Juniper EX, QFX, MX, PTX, and SRX deployments where short-reach 850nm fiber connectivity is required.
