Extreme Networks 10338 Compatible 10GBASE-T SFP+ Copper Transceiver for EXOS X-Series

EdgeOptic's Extreme Networks 10338 compatible is an Extreme-coded version of the EdgeOptic 10G-SFP-T multi-vendor 10GBASE-T copper SFP+ transceiver. The module EEPROM is programmed with Extreme-recognised vendor identity so EXOS accepts the part under its standard module validation. The transceiver is intended as a drop-in alternative to the native Extreme 10338 on equipment that carries the OEM SKU in its EXOS hardware compatibility documentation. This page covers the standard commercial-temperature 10338; the industrial-temperature 10338-I is a distinct Extreme SKU and is not the same part.

The transceiver operates per IEEE 802.3an for 10GBASE-T, IEEE 802.3bz for 2.5GBASE-T and 5GBASE-T, and IEEE 802.3ab for 1000BASE-T fallback. Reach is 30 m at 10G on Cat 6A or Cat 7 unshielded twisted pair. Electrical and management interfaces follow SFF-8431 and SFF-8432, the governing MSAs for SFP+ class copper modules. Operating temperature covers 0 to 65 °C commercial grade on a +3.3 V single supply, with CE and RoHS certification. The module draws more power than a typical optical SFP+ at the same data rate, which the EXOS G2 platforms accommodate on their 10G SFP+ ports.

Because the 10338 is a copper module, DOM telemetry through EXOS is scoped to the fields that apply to a non-optical SFP+: case temperature, supply voltage and link status. There is no laser, so transmit optical power, receive optical power and laser bias current do not exist on this part and are not reported. Management tooling that expects optical DDM values should treat this module as a copper transceiver.

Target deployment is the EXOS X-Series G2 family: X440-G2, X450-G2, X460-G2, X620, X670-G2 and X690. A critical deployment note applies to the 10338 across this family: Extreme's guidance is to populate 10338 modules in every other SFP+ port on the switch, with the adjacent port left vacant or occupied by a lower-power optical SFP+. The constraint is thermal, not firmware; 10GBASE-T copper modules dissipate more heat than optical SFP+ at the same data rate, and airflow across the cage stack must remain within the chassis design envelope. Engineers planning high-density 10338 deployments should review Extreme's published port-population guidance for the specific switch model before committing to a full copper population plan.
