Juniper compatible SRX-QSFP-40G-LR4 Description
EdgeOptic's SRX-QSFP-40G-LR4 compatible is a Juniper-coded version of the EdgeOptic 40G-QSFP-10 multi-vendor 40GBASE-LR4 transceiver, matching Juniper part number 740-073096. It is coded with Juniper-recognized EEPROM so the optic identifies correctly on Juniper SRX series security gateways. The SRX- ordering code is specific to the SRX firewall family and is distinct from Juniper's EX and QFX platform codes. Verify the part against the Juniper Hardware Compatibility Tool for your specific SRX model.
The module is a QSFP+ 40GBASE-LR4 optic that runs 40 Gigabit Ethernet to 10 km over duplex single-mode fiber on a double LC/UPC connector. Four DFB lasers multiplex CWDM lanes at 1271, 1291, 1311 and 1331 nm, received on a PIN photodiode. Per-lane launch power is −6 to +3 dBm, receiver sensitivity is −12.6 dBm, and RX overload is +3 dBm, for an average link budget of 6.6 dB. It operates from 0 to 70 °C and complies with IEEE 802.3ba Clause 87 and the QSFP+ MSA (INF-8438i, SFF-8436).
Juniper's Hardware Compatibility Tool lists the OEM SRX-QSFP-40G-LR4 without digital optical monitoring. EdgeOptic's compatible adds full DOM/DDM diagnostics, reporting module temperature, supply voltage, per-lane laser bias current and per-lane optical TX/RX power, so the optic can be monitored in service. This is an Ethernet transceiver for SRX firewall links; it does not carry OTN or SONET/SDH transport rates.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For volume pricing or deployment questions, contact our sales team.
Frequently Asked Questions
Does the SRX-QSFP-40G-LR4 support digital optical monitoring (DOM)?
Juniper's Hardware Compatibility Tool lists the OEM SRX-QSFP-40G-LR4 without digital optical monitoring. EdgeOptic's compatible adds DOM/DDM, so it reports per-lane temperature, supply voltage, laser bias, and optical TX/RX power for in-service monitoring on supported SRX platforms.
