Extreme compatible 10502 Description
EdgeOptic's 10502 compatible is an Extreme Networks-coded 25GBASE-SR SFP28 transceiver, a direct replacement for the Extreme Networks 10502 25Gb SFP28 SR Lite-FEC MMF Module (OEM part number 10502). It ships with Extreme-recognized EEPROM, so ExtremeXOS and SLX-OS identify the module as a native Extreme 10502 optic.
The module operates at 25GBASE-SR per IEEE 802.3by Clause 112. 850nm VCSEL transmitter, PIN photodiode receiver, LC/UPC duplex connector on OM3, OM4 or OM5 multimode fiber. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, optical budget 5.3 dB. Line rate covers 8.5 to 25.78 Gbps, so the same module serves 10GBASE-SR host ports on legacy line cards and 25GBASE-SR on current 25G linecards. Power draw is 0.3W maximum. DOM per SFF-8472, operating case temperature 0 to 70 degrees C.
The 10502 is the FEC-flexible variant in the Extreme 25G SFP28 line, distinct from the 10501 which supports RS-FEC only. The 10502 operates in three FEC modes and the reach envelope depends on which one is negotiated. RS-FEC (IEEE 802.3by Clause 108) is the mode required by IEEE for the full 100m OM4 and 70m OM3 reach envelope. Lite-FEC (IEEE 802.3 Clause 74 Base-R Firecode) reduces coding gain and correspondingly shortens reach relative to the RS-FEC path, at lower latency and lower computational overhead on the host. No-FEC operation is suitable for short in-rack links where FEC processing is not desired. For specific Lite-FEC and no-FEC reach envelopes on your fiber grade, consult the Extreme Networks 10502 datasheet or the Extreme compatibility matrix. The 10501 is RS-FEC only, so the 10502 is not simply a superset of the 10501 firmware profile; the two are distinct ordering codes for different FEC scopes.
Supported Extreme Networks platforms for the 10502: X670-G2 series (ExtremeXOS top-of-rack), X690 series (ExtremeXOS 1U aggregation), and SLX 9150 (SLX-OS data-center top-of-rack). On all three families the 10502 populates any SFP28 cage. The host port FEC mode should match the negotiated mode on the 10502: ExtremeXOS and SLX-OS both expose per-port FEC configuration, and the operator should verify the FEC mode selected at both ends during commissioning so the reach envelope matches the deployed fiber.
DOM registers for transmit power, receive power, laser bias current, module temperature and supply voltage are exposed through ExtremeXOS CLI and through standard SFP28-port SNMP MIBs. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112. The module carries CE, RoHS, Class 1 FDA and IEC 60825-1 certifications.

Frequently Asked Questions
What is the difference between the Extreme Networks 10501 and 10502?
Both are Extreme Networks 25GBASE-SR SFP28 modules on 850nm MMF, and they differ in which FEC modes they support. The 10501 is RS-FEC only per IEEE 802.3by Clause 108, with the IEEE-defined 100m OM4 and 70m OM3 reach envelope. The 10502 adds Lite-FEC (IEEE 802.3 Clause 74 Base-R Firecode) and a no-FEC mode alongside RS-FEC, which makes it the FEC-flexible variant in the Extreme 25G line. Reach depends on which FEC mode is negotiated on the link: the full RS-FEC envelope is 100m OM4 and 70m OM3; Lite-FEC and no-FEC envelopes are shorter and should be verified against the Extreme Networks 10502 datasheet for your fiber grade. Choose the 10502 when your deployment requires lower-latency Lite-FEC or needs to interoperate with a host that prefers Clause 74 FEC.
Which Extreme Networks switches support the 10502 SFP28 transceiver?
The 10502 is qualified on Extreme's 25G-capable EXOS and SLX-OS platforms: X670-G2 series, X690 series, and SLX 9150. Any SFP28 port on these chassis accepts the 10502. Specific firmware minimums vary by release; confirm your EXOS or SLX-OS image against Extreme's pluggable compatibility list if your switch image is older than the current GA track.
Can the 10502 reach 100 meters on OM4 fiber?
Yes, 100m on OM4 is achievable with RS-FEC (IEEE 802.3by Clause 108) configured on both link ends. This is the IEEE-defined 25GBASE-SR reach envelope and is the mode the 10502 uses when the link negotiates full FEC. With Lite-FEC (Clause 74 Base-R Firecode) or no-FEC operation, the reach envelope is shorter because the coding gain is reduced or absent; for the specific envelopes on your fiber grade, consult the Extreme Networks 10502 datasheet. If the host switch port is configured for Lite-FEC or no FEC and the fiber run is longer than the corresponding reach envelope, the link will either fail to establish or show elevated error counters; verify the FEC mode at both ends during commissioning.
Does the 10502 run on ExtremeXOS without the 'configure port unsupported-transceiver-warnings' workaround?
EdgeOptic's 10502 compatible is programmed with Extreme-recognized EEPROM, so ExtremeXOS and SLX-OS identify the module as a native Extreme 10502 optic. The unsupported-transceiver warning mechanism is the Extreme safety net for uncoded third-party modules and should not trigger for this SKU. If your environment enforces a stricter pluggable-validation policy or a custom EXOS image enables additional checks, validate in your lab before broad deployment.
