Product overview

The Juniper Networks JNP-SFP-25G-LR (740-071562) is a high-performance SFP28 optical transceiver designed for 25 Gigabit Ethernet applications over single-mode fiber. Supporting bi-directional data rates up to 25.78Gbps with backward compatibility to 10Gbps, it enables reliable connectivity up to 10km using 1310nm DFB transmitter and PIN receiver. Key features include hot-pluggable form factor, Duplex LC connector, Digital Diagnostic Monitoring (DDM) per SFF-8472, and low power consumption under 1.5W with +3.3V supply. Compliant with IEEE 802.3cc, SFP28 MSA, and RoHS standards, it operates in commercial temperature range of 0°C to 70°C. Ideal for data center top-of-rack, spine-leaf architectures, ISP metro networks, and enterprise campus deployments requiring low-latency, high-bandwidth links. The module supports host FEC, ensuring error-free transmission in dense 25G/100G environments. Its compact design (13.55x8.55x57.5mm, 0.15kg) facilitates seamless integration into Juniper MX, PTX, and QFX series platforms running Junos OS.

Frequently asked questions

What data rate and distance does Juniper 740-071562 support?

The JNP-SFP-25G-LR (740-071562) delivers 25.78Gbps bi-directional for 25GBASE-LR Ethernet over 10km SMF, with backward compatibility to 10.31Gbps. It features 1310nm wavelength, 8dB link budget, and supports applications in data centers requiring high-speed, long-reach connectivity.

What are the optical specifications of this SFP28 module?

Transmits at 1295-1325nm with -7 to 2dBm output power per lane, receives -13.3 to 2dBm sensitivity, extinction ratio >3.5dB, and stressed sensitivity -9.5dBm OMA. Uses DFB laser and PIN photodiode for SMF, ensuring compliance with 25GBASE-LR standards.

Is DDM supported and what is the power requirement?

Yes, full Digital Diagnostic Monitoring per SFF-8472 tracks temperature, voltage, bias, TX power, and RX power. Maximum power consumption is 1.5W from +3.3V supply, with commercial 0-70°C range ideal for enterprise and data center use.

What Juniper platforms is 740-071562 compatible with?

Compatible with MX304, MX304-LMIC16, ACX7509-FPC-20Y, PTX series, and QFX switches running Junos OS 22.3R1+. Hot-pluggable SFP28 slots support seamless integration for 25G Ethernet deployments.

What fiber and connector types are required?

Requires Duplex LC/UPC connectors on 9/125µm SMF cable. Provides 10km reach with 8dB budget, suitable for intra-building and campus links without active components.

Does it support breakout or multi-rate operation?

No breakout capability, but supports 8.5-28.1Gbps rates including 25G Ethernet (25.78Gbps) and 10G (10.31Gbps). Host FEC required for optimal performance in Juniper systems.
