Juniper 10GBASE-LR SFP+ Transceiver — 10km Single-Mode Fiber

The Juniper SFPP-10G-LR-C is a 10GBASE-LR SFP+ optical transceiver delivering 10GbE over single-mode fiber up to 10km at 1310nm (1355nm variant) via duplex LC connector — Juniper-coded in alphanumeric format for plug-and-play compatibility across Juniper EX, QFX, MX, PTX, and SRX platforms requiring standard 10G SMF connectivity for data center, campus, and service provider applications.

Key Features

Frequently Asked Questions

What is the difference between SFPP-10G-LR-C and 740-140352?

Both are Juniper-genuine 10GBASE-LR SFP+ transceivers with identical optical specifications. SFPP-10G-LR-C uses the alphanumeric part number format, while 740-140352 uses the numeric format. Both are fully interchangeable on supported Juniper platforms.

What is the difference between SFPP-10G-LR-C and SFPP-10G-SR-C?

The SFPP-10G-LR-C uses 1310nm laser for long-reach SMF connectivity up to 10km, while the SFPP-10G-SR-C uses 850nm VCSEL for short-reach MMF connectivity up to 300m (OM3) or 400m (OM4). Select based on your fiber type (SMF vs. MMF) and link distance requirements.

Does SFPP-10G-LR-C support DDM monitoring?

Yes — DDM/DOM is fully supported, enabling Junos OS to report TX/RX optical power, temperature, voltage, and bias current in real time for proactive transceiver health monitoring via CLI and SNMP.

The Juniper SFPP-10G-LR-C delivers Juniper-coded 10GBASE-LR connectivity over 10km single-mode fiber with DDM monitoring and broad platform compatibility — providing the standard 10G SMF transceiver for Juniper EX, QFX, MX, PTX, and SRX deployments where long-reach fiber connectivity beyond MMF distance limitations is required.
