Juniper compatible EX-SFP-1GE-LX Description

EdgeOptic's EX-SFP-1GE-LX compatible is a Juniper-coded version of the EdgeOptic 1.25G-SFP-10D multi-vendor 1000BASE-LX SFP transceiver. Juniper catalogs this module under part number 740-011614 and cross-references it as equivalent to the generic SFP-1G-LX-C optic class. Juniper's Hardware Compatibility Tool lists the same part number 740-011614 for the SRX-SFP-1GE-LX, QFX-SFP-1GE-LX and SRX-SFP-1GE-LX-ET ordering codes as well. The module supports Digital Optical Monitoring, so Tx power, Rx power, temperature and supply voltage are all readable in real time.

The module uses duplex LC/UPC connectors over single-mode fiber, transmitting and receiving at 1310nm across a 100nm passband from 1260 to 1360nm. It is rated for 10 km with a 13 dB average link budget, built around an FP laser transmitter and a PIN photodiode receiver. Minimum TX power is -9 dBm, maximum TX power is 3 dBm, RX sensitivity is -22 dBm and RX overload is -3 dBm. The underlying hardware spans a 1.063 to 1.25 Gbps data rate; on Junos EX, SRX and QFX platforms the classified application is 1000BASE-LX Gigabit Ethernet, with chromatic dispersion tolerance of 70 to 100 ps/nm.

On Junos based EX, SRX and QFX platforms, optical levels are readable through the 'show interfaces diagnostics optics' command, which reports the same Tx power, Rx power and alarm thresholds the module exposes over Digital Optical Monitoring. Juniper classifies EX-SFP-1GE-LX as a 1000BASE-LX Gigabit Ethernet optic, the same classification carried by its SRX-SFP-1GE-LX, QFX-SFP-1GE-LX and SRX-SFP-1GE-LX-ET siblings.

Operating temperature is rated 0 to 70 C for standard commercial deployments, running on a single +3.3V power supply. Compliance covers CE marking, Class 1 laser safety per FDA regulations and IEC 60825-1, the INF-8074i and SFP MSA mechanical specifications, and RoHS.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project-quantity pricing or alternative vendor coding, contact our sales team.

Frequently Asked Questions

Is EX-SFP-1GE-LX the same part as SRX-SFP-1GE-LX or QFX-SFP-1GE-LX?

Yes, the same Juniper part number is shared across those codes. Juniper's Hardware Compatibility Tool lists part number 740-011614 for EX-SFP-1GE-LX, SRX-SFP-1GE-LX, QFX-SFP-1GE-LX and SRX-SFP-1GE-LX-ET, and a Juniper community discussion of the part number confirms the same mapping. Deployments requiring extended temperature range should verify against Juniper's own HCT entry for each code: the '-ET' suffix on SRX-SFP-1GE-LX-ET typically denotes an extended thermal spec, which is not confirmed identical to the standard commercial rating of the other three codes.

Is EX-SFP-1GE-LX the same thing as an 'SFP LX10' module?

Juniper classifies EX-SFP-1GE-LX as a 1000BASE-LX Gigabit Ethernet optic in its Hardware Compatibility Tool. 'SFP LX10' is a naming convention used across the compatible optics channel for this class of 1310nm, 10 km single-mode module, not a Juniper part designation, so orders should reference EX-SFP-1GE-LX or 740-011614 directly to avoid confusion.
