Juniper compatible SFP-1G-SX-C Description
EdgeOptic's SFP-1G-SX-C 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.
The module carries a minimum guaranteed optical budget of 7.5 dB, enough to drive 550m over OM2 multimode fiber (50/125, 500 MHz·km) and 275m 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. Built to the INF-8074i SFP MSA, +3.3V supply, CE/RoHS, Class 1 laser safety.
Juniper lists SFP-1G-SX-C as a Common Optic, a single cross-platform ordering code certified across Juniper routing, switching, and security product lines rather than a platform-specific optic. EdgeOptic codes the EEPROM so Junos accepts the module without a software override. One spec note worth checking before ordering: the Juniper SFP-1G-SX-C is rated for extended temperature operation, -10 to +85°C, while the EdgeOptic compatible is specified for the commercial 0 to 70°C range. For extended-temperature deployments, confirm the temperature rating your installation requires.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For platform-specific questions or extended-temperature requirements, contact our sales team.
Frequently Asked Questions
Is the Juniper SFP-1G-SX-C a common optic, and which platforms does it support?
Yes. Juniper classifies SFP-1G-SX-C as a Common Optic, meaning it is a single ordering code certified for use across Juniper routing, switching, and security platforms rather than being tied to one product line. The Juniper datasheet lists support including EX9200, QFX3500, QFX5100/5110/5120, and QFX10000 series. Verify your exact chassis and Junos release against the Juniper Hardware Compatibility Tool before ordering.
What is the operating temperature range, and how does it differ from the EdgeOptic compatible?
The Juniper SFP-1G-SX-C is rated for extended temperature operation, -10 to +85°C, per the Juniper Hardware Compatibility Tool. The EdgeOptic compatible is specified for the commercial 0 to 70°C range. For outdoor, industrial, or other extended-temperature deployments that require the full -10 to +85°C window, contact our sales team to confirm the right part for your environment.
