Juniper compatible JNP-SFP-25G-SR Description
EdgeOptic's JNP-SFP-25G-SR compatible is a Juniper-coded 25GBASE-SR SFP28 transceiver, a direct replacement for Juniper Networks' JNP-SFP-25G-SR optical module (Juniper orderable part number 740-068639). It ships with Juniper-recognized EEPROM, so QFX and EX switching chassis identify the module as a native Juniper 25G SR optic. JNP-SFP-25G-SR is the Juniper product model name; 740-068639 is the OPN used in Juniper procurement, SmartNet spare-part ordering and distributor catalogs. Both strings reference the same module.
Optical performance follows IEEE 802.3by Clause 112: 100m reach on OM4/OM5 multimode fiber, 70m on OM3. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, link budget 5.3 dB with host RS-FEC (IEEE 802.3by Clause 108). The module uses an 850nm VCSEL transmitter, a PIN photodiode receiver, and an LC/UPC duplex connector. DOM follows SFF-8472. Line rate is 8.5 to 25.78 Gbps, covering both 10GBASE-SR and 25GBASE-SR host rates. Power consumption is 0.3W maximum over the 0 to 70°C commercial case temperature range.
JNP-SFP-25G-SR is validated against the 25G-capable Juniper hardware line. On the QFX data-center switching side: QFX5120 Series (25G leaf; QFX5120-48Y carries 48x 25G SFP28 server-facing ports with 8x 100G QSFP28 uplinks; QFX5120-48YM carries the same port map with extended-temperature optics and expanded forwarding-table sizing for service-provider deployments). QFX5220 Series (100G/400G spine where JNP-SFP-25G-SR serves the 25G breakout role; 4x25G from a single 100G QSFP28 cage via breakout fiber, typical in 100G-to-25G spine-leaf topologies). On the EX campus switching side: EX4650 Series (25G high-density enterprise campus). Confirm the exact sub-model and Junos release against the Juniper Hardware Compatibility Tool at apps.juniper.net/hct before commissioning; Juniper updates the HCT alongside Junos releases and platform interface changes.
On OPN disambiguation: 740-068639 is the Juniper orderable part number for JNP-SFP-25G-SR. It is not the same as 740-071562, which is a separate Juniper OPN in a different product class and should not be substituted. Some procurement systems surface only the leading-zero-stripped OPN fragment (068639) rather than the full 740-068639 string, especially when legacy distributor feeds are involved; both representations reference the same module, but the canonical Juniper OPN for Junos-side compatibility validation is 740-068639 in full.
DOM readout on Juniper platforms surfaces through Junos transceiver telemetry views where the platform exposes per-port SFP28 optical diagnostics. The SFF-8472 parameter set (transmit power, receive power, laser bias, case temperature, supply voltage) is reported in the Junos transceiver-diagnostics output; the exact CLI path varies by Junos release and chassis PIC type. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112. Certifications: CE, RoHS, Class 1 FDA, IEC 60825-1.

Frequently Asked Questions
Which Juniper QFX and EX platforms accept the JNP-SFP-25G-SR?
The 25G-capable Juniper hardware families targeted by this OPN: QFX5120 Series (25G data-center leaf, including QFX5120-48Y and QFX5120-48YM), QFX5220 Series (100G/400G spine with 25G breakout from QSFP28 cages), and EX4650 Series (25G high-density enterprise campus). The Juniper Hardware Compatibility Tool at apps.juniper.net/hct carries the definitive sub-model and Junos-release validation data. That tool is the authoritative reference for commissioning decisions in production networks, particularly for mixed 10G/25G port-profile configurations.
Is 740-068639 the same as JNP-SFP-25G-SR?
Yes. 740-068639 is the Juniper orderable part number for JNP-SFP-25G-SR. Juniper catalogs the module under JNP-SFP-25G-SR (the product model name) and 740-068639 (the OPN used in SmartNet spare-part ordering and Juniper price lists). Both identifiers reference the same 25GBASE-SR SFP28 module. Some Juniper procurement workflows surface only the shorter '068639' fragment, which is the tail of the same OPN; the canonical string for Junos-side compatibility validation is 740-068639 in full.
Does the JNP-SFP-25G-SR operate at 10G on QFX5120 mixed-speed deployments?
The module's line-rate envelope is 8.5 to 25.78 Gbps, which covers the 10GBASE-SR host rate alongside 25GBASE-SR. On QFX5120 and QFX5220, the 25G SFP28 ports also support 10GBASE-SR when the port is configured for 10G operation. The module sits inside the multi-rate envelope at either speed. For a specific Junos release and chassis combination, the Junos port-profile configuration reference documents the exact per-port speed-change procedure on the QFX platform.
What is the difference between Juniper OPN 740-068639 and 740-071562?
740-068639 and 740-071562 are two distinct Juniper ordering part numbers. 740-068639 is the OPN targeted by this page: the JNP-SFP-25G-SR short-reach MMF SFP28. 740-071562 is a separate Juniper catalog entry in a different product class with its own specification parameters and chassis validation list. Do not substitute one OPN for the other in a Juniper BOM; reconcile the exact OPN your Juniper quote or price list specifies against the chassis-specific validation before order placement.
