Juniper compatible QFX-SFP-10GE-USR Description
EdgeOptic's 10G-SFP-300 compatible is a Juniper-coded 10G USR (Ultra Short Reach) SFP+ that replaces the QFX-SFP-10GE-USR. USR is a vendor-specific designation, not an IEEE 802.3 standard. It targets intra-rack and top-of-rack connections in Juniper QFX data centre switches, including the QFX5100, QFX5200, and QFX10000 series. The QFX prefix in the part number identifies modules qualified for Juniper's QFX switching platform. EdgeOptic programs the EEPROM with Juniper-recognized vendor data, so the module identifies correctly in Junos without unsupported-optic alarms. Typical deployment: leaf switches in a QFX5100-based IP fabric where all 10GbE server uplinks stay within a single row of racks. Optical parameters: 850 nm VCSEL transmitter, PIN photodiode receiver, 10.3125 Gbps line rate. USR reach is 100 m over OM3 and 150 m over OM4 multimode fibre, with a power budget per vendor datasheet.
USR differs from standard 10GBASE-SR in both reach and power budget. SR modules are rated for 300 m OM3 / 400 m OM4 and follow IEEE 802.3ae specifications. USR modules trade reduced reach for a relaxed power budget that lowers power consumption in high-density leaf-spine fabrics where link distances rarely exceed a single rack row. The two module types are not interchangeable in distance planning: installing a USR optic on a 200 m OM3 span will not close the link. Verify the fibre path length during commissioning and select SR if any span exceeds the USR distance limits. DDM/DOM telemetry reports TX power, RX power, temperature, bias current, and supply voltage for proactive link monitoring. The 10G-SFP-300 chipset supports multi-rate operation from 1.25 to 11.32 Gbps, covering 10GbE and lower-rate Ethernet modes depending on port configuration. LC duplex connector, 0 to 70 C operating range.
Every QFX-SFP-10GE-USR compatible is tested against current Junos releases for QFX platforms and validated against Juniper's vendor ID requirements. Quality checks include optical power measurement, connector inspection, and EEPROM data verification. The module is CE/RoHS certified and compliant with SFP+ MSA (SFF-8431/SFF-8432).

Frequently Asked Questions
What is the actual reach of the QFX-SFP-10GE-USR compared to a standard SR module?
USR reach is 100 m over OM3 and 150 m over OM4 multimode fibre. Standard 10GBASE-SR reaches 300 m OM3 / 400 m OM4. USR trades distance for a relaxed power budget suited to short intra-rack links in leaf-spine topologies. If the link exceeds 100 m on OM3, use an SR-coded module instead.
Can the QFX-SFP-10GE-USR be used in Juniper EX or MX series switches?
The QFX-SFP-10GE-USR is qualified for QFX-series data centre switches. EX and MX platforms have their own qualified USR or SR part numbers (e.g., EX-SFP-10GE-USR, SFP-10GE-USR for MX). While the optics are physically identical, Junos validates the part number against a platform-specific approved list. Using the QFX-prefixed SKU in an EX or MX may generate an unsupported-optic message.
