Juniper JNP-SFP-25G-LR (740-071562) Compatible 25GBASE-LR SFP28

EdgeOptic's JNP-SFP-25G-LR compatible is a Juniper-coded dual-rate 10G/25G LR SFP28 transceiver and the Juniper-coded variant of the EdgeOptic 25G-SFP28-10 multi-vendor 25GBASE-LR catalog. The optic is also identified by Juniper's ordering part number 740-071562 in the Juniper Hardware Compatibility Tool, so partner quotes, Junos inventory output, and Juniper purchase orders that reference 740-071562 map to the same physical module. The transceiver carries 10 Gigabit Ethernet (10.31 Gbps) and 25 Gigabit Ethernet (25.78 Gbps) over a single G.652 SMF pair at 1310 nm, terminated with a duplex LC/UPC connector.

The transmitter is a DML driving the 1310 nm LC duplex; the receiver is a PIN photodiode. Optical specifications: TX output power −7 to +2 dBm, RX sensitivity −12 dBm, RX overload +3 dBm, minimum extinction ratio 3.5 dB, and a 5 dB optical link budget over the 10 km specified reach on G.652 SMF. On spans above 8 km, calculate end-to-end insertion loss against the 5 dB budget rather than relying on the nominal 10 km figure, because real reach is loss-limited by installed fiber attenuation, splice loss, and connector loss. The module operates 0 to 70 °C on a +3.3 V single supply with 1.2 W maximum power consumption.

At 25G operation the host MAC performs RS(528,514) RS-FEC; the module itself has no built-in FEC. Junos FEC default behavior for 25GBASE-LR varies by platform and OS release; both link partners must agree on the FEC mode, and a mismatch produces link-down events that do not surface as optical errors. Verify the FEC profile per interface against the relevant Junos configuration guide before commissioning. At 10G operation the optic behaves as a standard 10GBASE-LR module and host-side FEC is not required, but the host port must support dual-rate selection between 10G and 25G on its SFP28 cage.

The module ships with Juniper-recognized EEPROM coding so the optic registers cleanly under Junos and Junos EVO and does not require third-party-transceiver override commands. DDM diagnostics report TX power, RX power, module temperature, laser bias, and supply voltage in real time per SFF-8472 and are visible through the standard Junos transceiver diagnostics interfaces. Platform support spans Juniper QFX series 25G SFP28 cages and EX series 25G uplink slots; verify the specific platform, chassis, and Junos release against the Juniper Hardware Compatibility Tool at apps.juniper.net/hct before ordering. Typical applications: data center 25G aggregation, campus 25G uplinks, and metro long-reach connections. Conforms to IEEE 802.3cc, SFF-8431, SFF-8432, SFF-8472, and the SFP28 MSA.
