Cisco compatible FET-10G Description
EdgeOptic's Cisco FET-10G compatible is the 10GBASE-SR SFP+ alternative for Cisco's proprietary Fabric Extender Transceiver, designed for Nexus 2000 FEX fabric links. The original FET-10G is a 10 Gbps 10GBASE-USR SFP+ rated to 100 m on OM3 and 125 m on OM4 multimode fiber, and is qualified for the fabric link between Nexus 2000-series Fabric Extenders and their parent switches. The EdgeOptic 10GBASE-SR SFP+ shares the same SFP+ cage and LC duplex interface as the FET-10G, ships with Cisco-recognized EEPROM coding for the FET-10G ordering code, and extends the reach envelope to 300 m on OM3 and 400 m on OM4 multimode fiber.
The replacement is built to IEEE 802.3ae 10GBASE-SR with a 6.1 dB optical budget, transmit power between −5 and 0 dBm, and receive sensitivity better than −11.1 dBm. The FET-10G is FEX-uplink specific in Cisco's product positioning: it connects Nexus 2000 Fabric Extenders to Nexus 5000, 6000, 7000, and 9000-series parent switches across the FEX fabric link, and is not interchangeable with SFP-10G-SR on standard 10G switch host ports outside the FEX fabric topology. The EdgeOptic SR replacement preserves the FEX-uplink usage while supporting the longer SR reach envelope for FEX deployments that span beyond 100 m on OM3.
Cisco-recognized EEPROM coding identifies the module under the FET-10G ordering code that the Nexus chassis expects, so the SFP+ registers cleanly on the FEX fabric port without third-party transceiver warnings. Digital diagnostics per SFF-8472 reports temperature, supply voltage, transmit bias current, transmit power, and receive power on every read. The EdgeOptic SR replacement is governed by IEEE 802.3ae Clause 52 for 10GBASE-SR multimode operation, and SFF-8431 governs the SFP+ electrical and mechanical interface. Verify the specific Nexus parent and Nexus 2000 FEX model, the NX-OS release, and the FEX fabric configuration against the Cisco Nexus 2000 FEX configuration guide before commissioning.

Frequently Asked Questions
Which Cisco parent switches accept the FET-10G for Nexus 2000 FEX uplinks?
The Cisco FET-10G is qualified for Nexus 2000-series Fabric Extender uplinks connecting back to the Nexus 5000, 6000, 7000, and 9000-series parent switches that support the FEX fabric link configuration. Verify the specific parent platform model and the NX-OS release on the deployment side against the Cisco Nexus 2000 FEX configuration guide before commissioning, since FEX parent support varies by chassis generation and software train.
Can the FET-10G be used on a standard 10G SFP+ port instead of a FEX fabric uplink?
No. The Cisco FET-10G is a Fabric Extender Transceiver designed exclusively for the FEX fabric link between Nexus 2000 Fabric Extenders and their parent switches. Standard 10G SFP+ host ports outside the FEX fabric topology require a 10GBASE-SR SFP+ such as SFP-10G-SR. For deployments running FEX-equipped Nexus chassis with the FEX fabric ports designated, the FET-10G replacement applies; for standard 10G SFP+ uplinks, order the SFP-10G-SR compatible instead.
