Juniper compatible EX-SFP-10GE-SR Description
EdgeOptic's EX-SFP-10GE-SR compatible is a Juniper-coded version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver. The EX- prefix in Juniper's accessory naming identifies optics qualified for the EX-series switching line; Juniper also catalogs the same physical module under spare-part code 740-021308. Engineers ordering against a Juniper service contract or RMA spare drawer typically search for the 740-021308 code, while engineers ordering against a fresh switch quote use the EX-SFP-10GE-SR ordering part number.
Optical specs follow the 10G-SFP-300 root: 850 nm transmit and receive, 20 nm bandwidth (840 to 860 nm), 300 m over OM3 and 400 m over OM4 / OM5 multimode fiber, duplex LC/UPC connector, 6.1 dB average link budget. Transmit power is −5 to 0 dBm, receiver sensitivity is −11.1 dBm, and receiver overload is 0 dBm. The transmitter is a VCSEL laser, the receiver a PIN photodiode, and DOM/DDM is supported per SFF-8472, exposed on Junos via the show interfaces diagnostics optics command. The 1.25 to 11.32 Gbps multi-rate envelope per SFF-8431 also lets the module rate-select to 1000BASE-SX (1.25 Gbps) on dual-rate Juniper EX SFP+ ports, which is useful during phased 1G to 10G upgrades on the same multimode plant.
Standard target chassis are Juniper EX2300, EX3400, EX4300, EX4600, and EX9200 switches with SFP+ slots, per Juniper's Hardware Compatibility Tool. The EdgeOptic compatible carries Juniper-recognized vendor identification so the optic appears as a recognized SFP+ on Junos. For QFX-series chassis (which use the QFX-SFP-10GE-SR ordering code), confirm cross-platform support against the Juniper HCT before substituting EX-SFP-10GE-SR into a QFX slot, since EEPROM acceptance varies by Junos release. Operating temperature is 0 to 70 °C commercial.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions
Is Juniper part number 740-021308 the same module as EX-SFP-10GE-SR, and does this compatible cover both?
Yes. 740-021308 is Juniper's spare / service-part code for the same physical module that ships under the ordering part number EX-SFP-10GE-SR. The two codes route through different Juniper catalogs (740-xxxxxx is the spare-PN convention; EX-SFP- is the OPN convention) but reference the same 10GBASE-SR SFP+ optic. The EdgeOptic compatible covers both ordering paths with Juniper-recognized EEPROM, so engineers searching by either code arrive at the same replacement transceiver.
Will EX-SFP-10GE-SR also work on Juniper QFX-series switches, or do I need QFX-SFP-10GE-SR?
Optically the two parts share the same 10GBASE-SR 850 nm multimode specification, but Juniper catalogs them under separate ordering codes for the EX-series and QFX-series families. Some Junos releases on QFX chassis accept EX-SFP-10GE-SR transparently; other releases enforce the QFX-prefixed accessory line. Match the part to the chassis line per Juniper's Hardware Compatibility Tool entry for the specific switch model and Junos release before substituting. For mixed EX / QFX deployments where consistent stock matters, the safe path is to keep the EX optics in EX slots and order QFX-SFP-10GE-SR for QFX slots until the HCT confirms cross-acceptance for that Junos build.
