Extreme Networks 10309 Compatible 10GBASE-ER SFP+ 40km

EdgeOptic's 10309 compatible is an Extreme Networks-coded version of the EdgeOptic 10G-SFP-40 multi-vendor 10GBASE-ER SFP+ transceiver. It carries the numeric 10309 part number that Extreme Networks uses for its 10GBASE-ER reach class, and ships with EEPROM coded for recognition on Extreme Networks ExtremeXOS and Switch Engine switches. The module runs 10 Gigabit Ethernet and 1 Gigabit Ethernet over a duplex single-mode fiber pair, matching the original part across optical performance, form factor, and the SFP MSA pinout.

The transmitter operates at a nominal 1550 nm wavelength with launch power between −1 and +4 dBm. The receiver holds a sensitivity of −16 dBm with an overload point of 0 dBm, giving a 15 dB link budget across the span. Chromatic dispersion tolerance covers the 800 to 1000 ps/nm range, which supports the rated 40 km reach over standard G.652 single-mode fiber. The connector is a duplex LC/UPC interface for the standard transmit and receive fiber pair.

Digital optical monitoring is supported per the SFF-8431 specification. The module reports real-time transmit power, receive power, laser bias current, supply voltage, and transceiver temperature, so operators can read link health directly from the switch without external test equipment. The diagnostic data also helps confirm fiber loss budget during commissioning and gives an early signal when a link begins to degrade. The transceiver runs on a single +3.3 V supply and is rated for the 0 to 70 °C commercial temperature range. It is built to the SFP MSA mechanical and electrical definition and the SFF-8431 SFP+ specification, and carries CE and RoHS marking with Class 1 laser safety per IEC 60825-1.

The 40 km extended reach suits data center site interconnection, metro and carrier access aggregation, and building-to-building campus backbone links where the fiber run exceeds the limits of an LR-class optic. The 10309 carries multiple vendor codes across the EdgeOptic catalog, so a single optical design serves a wide range of switch platforms while keeping the optical performance, EEPROM behavior, and SFP MSA footprint identical to the original part. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the 10309 compatible ships next business day from EU stock with a lifetime warranty.
