Juniper compatible QFX-SFP-10GE-SR Description
QFX-SFP-10GE-SR is the Juniper ordering code for a 10GBASE-SR SFP+ transceiver qualified on the QFX data-centre switching family. The QFX-prefix distinguishes it from Juniper's EX-SFP-10GE-SR (campus EX series), SFPP-10GE-SR (generic routing and enterprise), and SFPP-10G-SR-C (platform variant commonly used on MX line cards). The four SKUs are optically identical 10GBASE-SR modules, but each carries platform-specific EEPROM identifiers that Junos verifies against the chassis hardware model.
QFX-SFP-10GE-SR is specified for QFX3500, QFX3600, QFX5100-24Q / 48S / 96S, QFX5110-48S / 32Q, QFX5120-48Y / 48T, and the QFX10002 and QFX10008 modular chassis. In a standard top-of-rack deployment the module lights up server-facing 10GbE ports on a QFX5100-48S or QFX5110-48S facing dual-homed hosts with LACP, and on uplink ports into an EVPN-VXLAN spine built on QFX10002 or QFX10008. On QFX platforms that support 40G QSFP+ breakout accept QFX-SFP-10GE-SR in the 4x10GbE sub-channels when a QSFP+ port is split using MPO-to-LC breakout cabling.
The optic itself follows IEEE 802.3ae 10GBASE-SR: 850 nm VCSEL source, 6.1 dB minimum link budget, 300 m rated reach on OM3 and 400 m on OM4, LC/UPC duplex. DDM per SFF-8472 reports Tx and Rx power, temperature, supply voltage, and bias current through show interfaces diagnostics optics on Junos. EdgeOptic codes the transceiver with the Juniper OUI and QFX-SFP-10GE-SR PN string, so show chassis hardware recognizes the module without needing the optics-options unknown-transceiver override in set chassis pic configuration.
If the design mixes QFX and EX switches, keep EX-SFP-10GE-SR on the EX4300 / EX4600 side and QFX-SFP-10GE-SR on the QFX side rather than using a single SKU for both; Junos will link up cross-family but the hardware-inventory report looks cleaner with the chassis-matched PN. For MX routers and SRX firewalls, use SFPP-10GE-SR instead.

Frequently Asked Questions
How does QFX-SFP-10GE-SR differ from EX-SFP-10GE-SR, SFPP-10GE-SR, and SFPP-10G-SR-C?
All four are 10GBASE-SR optics with the same 850 nm 300 m OM3 optical design. The SKU difference is platform scope: QFX-SFP-10GE-SR targets the QFX data-centre family, EX-SFP-10GE-SR targets the EX campus family, SFPP-10GE-SR is the generic code used on MX routing and SRX firewalls, and SFPP-10G-SR-C is the Cloud/service-provider variant with extended-temperature screening on some MX Series line cards.
Which QFX chassis and line cards does QFX-SFP-10GE-SR fit?
QFX3500, QFX3600, QFX5100-24Q / 48S / 96S, QFX5110-48S and QFX5110-32Q, QFX5120-48Y / 48T, QFX10002-36Q / 72Q, QFX10008, and QFX10016. It also fits the SFP+ breakout ports on QFX platforms with QSFP+ (40G) breakout support accept QFX-SFP-10GE-SR in the 4x10GbE sub-channels via MPO-to-LC breakout cables.
Will Junos recognize the module without the unknown-transceiver override?
Yes. EdgeOptic programs QFX-SFP-10GE-SR with the Juniper OUI and the exact QFX-SFP-10GE-SR PN and revision string. show chassis hardware lists the module with the expected vendor name, and show interfaces diagnostics optics returns full DDM readings. No optics-options unknown-transceiver configuration is needed on any current Junos release.
