Juniper SRX-SFP-10GE-ER Compatible 10GBASE-ER SFP+ Module

EdgeOptic's SRX-SFP-10GE-ER compatible is a Juniper-coded version of the EdgeOptic 10G-SFP-40 multi-vendor 10GBASE-ER SFP+ transceiver, built for 10 Gigabit Ethernet links up to 40 km over duplex single-mode fiber. It carries the Juniper SRX Series ordering code SRX-SFP-10GE-ER, and the EEPROM is coded with the Juniper vendor identifier so Junos recognizes the module on SRX Series security gateways.

The module operates at 1550 nm over duplex single-mode fiber with an LC/UPC connector. Transmit power is rated from −1 to +4 dBm, receiver sensitivity is better than −16 dBm, and receiver overload is 0 dBm, giving a 15 dB link budget for spans up to 40 km. The protocol scope on SRX Series security gateways is Ethernet only: 10 Gigabit Ethernet at 10.3125 Gbps and 1 Gigabit Ethernet at 1.25 Gbps. The module runs on a single 3.3 V supply across the 0 to 70 °C standard operating range.

Digital optical monitoring is supported per the SFF-8431 specification, reporting module temperature, supply voltage, laser bias current, transmit optical power and receive optical power in real time. Engineers can read these values from the Junos optics diagnostics output to confirm both ends of a link sit within spec during commissioning. The transceiver complies with the SFP MSA and SFF-8431 electrical interface, carries CE marking, meets RoHS requirements, and is rated IEC 60825-1 Class 1 for laser safety.

The receiver tolerates chromatic dispersion in the 800 to 1000 ps/nm range typical of a 40 km 1550 nm single-mode path, and the data path covers the 1.25 to 11.32 Gbps range that 10 Gigabit and 1 Gigabit Ethernet require. SRX-SFP-10GE-ER suits long-reach security gateway uplinks, branch-to-data-center handoffs and metro Ethernet connections where a 40 km single-mode span is required. It works on Juniper SRX Series security gateways; verify the module against the transceiver table for your specific SRX model and Junos release before deployment.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, every module ships after optical parameter measurement and EEPROM data validation. The SRX-SFP-10GE-ER compatible ships next business day from EU stock with a lifetime warranty. For deployment questions or a tailored quote, contact our sales team.
