Juniper compatible SRX-SFP-1GE-SX Description
EdgeOptic's SRX-SFP-1GE-SX compatible is a Juniper-coded version of the EdgeOptic 1.25G-SFP-550D multi-vendor 1000BASE-SX transceiver. It runs Gigabit Ethernet at 1.25 Gbps (IEEE 802.3z) and 1G Fibre Channel SW at 1.0625 Gbps over duplex multimode fiber, with an 850nm VCSEL transmitter and a PIN photodiode receiver.
With a 7.5 dB optical budget, the module reaches 550 m over OM2 multimode fiber (50/125, 500 MHz·km) and 275 m over OM1 (62.5/125). It uses a duplex LC/UPC interface and supports DDM/DOM diagnostics for live monitoring of optical power, bias current, and temperature. The module operates over the commercial 0 to 70°C range, built to the INF-8074i SFP MSA, with a +3.3V supply and CE/RoHS/Class 1 laser safety.
SRX-SFP-1GE-SX carries Juniper part number 740-011613 and is the SRX-series ordering code for this 1G SX SFP. EdgeOptic codes the EEPROM with Juniper-recognized data so the module identifies correctly on Juniper equipment. Works on Juniper SRX Series firewalls and services gateways; verify your platform's transceiver table in the Juniper Hardware Compatibility Tool before ordering.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For ordering-code confirmation or platform questions, contact our sales team.
Frequently Asked Questions
What is the difference between SRX-SFP-1GE-SX and SRX-SFP-1GE-SX-ET?
SRX-SFP-1GE-SX-ET is a separate Juniper ordering code for an extended-temperature variant of this module, listed as its own model in the Juniper Hardware Compatibility Tool. This page covers the standard commercial-temperature SRX-SFP-1GE-SX (0 to 70°C). If you need the extended-temperature build, contact our sales team.
I'm ordering for an SRX firewall but found EX-SFP-1GE-SX listed with the same part number. Which do I use?
Juniper markets this 1000BASE-SX SFP under several platform-prefixed ordering codes that share part number 740-011613 in the Juniper Hardware Compatibility Tool, and the HCT names SFP-1G-SX-C as the common optic equivalent for both codes. SRX-SFP-1GE-SX is the SRX-series ordering code, so for an SRX firewall or services gateway, order the SRX-SFP-1GE-SX compatible. Confirm the exact code your chassis expects in the Juniper Hardware Compatibility Tool.
