Juniper compatible QFX-SFP-10GE-ER Description

EdgeOptic's QFX-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 ordering code QFX-SFP-10GE-ER and Juniper part number 740-030128, and the EEPROM is coded with the Juniper vendor identifier so Junos recognizes the module on QFX Series switches.

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 QFX Series data-center fabric switches 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 are 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. QFX-SFP-10GE-ER suits long-reach data-center interconnect, campus aggregation uplinks and metro Ethernet handoffs where a 40 km single-mode span is needed. It works on Juniper QFX Series switches; verify the module against the transceiver table for your specific chassis 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 QFX-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.

Frequently Asked Questions

Will the QFX-SFP-10GE-ER compatible trigger an unsupported optic warning on Juniper QFX switches?

EdgeOptic codes the EEPROM with the Juniper vendor identifier so Junos recognizes the module on QFX Series switches. Junos logs a warning for transceivers it does not recognize, but it does not block traffic on the port. With the Juniper vendor code in place that warning is addressed. If you see an unexpected message, confirm the module status in the Junos optics diagnostics output and check the transceiver table for your switch model and Junos release.

Is QFX-SFP-10GE-ER the same optic as EX-SFP-10GE-ER or SFPP-10GE-ER?

QFX-SFP-10GE-ER is the Juniper ordering code used for the QFX Series. EX-SFP-10GE-ER is the EX Series ordering code and SFPP-10GE-ER is another Juniper ordering code for the same 10GBASE-ER optical class, 1550 nm over 40 km of single-mode fiber. The optical specification is the same across these codes, but each is coded for its platform line. Order the QFX-prefixed code for QFX Series switches and confirm the code your switch expects in the Juniper transceiver guide.
