SonicWall 02-SSC-8390 Compatible 25GBASE-SR SFP28 for NSa 6700 and NSsp Firewalls

EdgeOptic's 02-SSC-8390 compatible is a SonicWall-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor SFP28 dual-rate 10G/25G SR transceiver. 02-SSC-8390 is SonicWall's ordering code for the 25Gb SFP28 SR transceiver specified against NSa 6700 and NSsp firewalls with 25G SFP28 interfaces. The module is programmed with SonicWall-recognized EEPROM vendor and part-number strings so SonicOS reads the optic against the qualified transceiver table at insertion.

Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber, with 10GBASE-SR support per IEEE 802.3ae on dual-rate SFP28 host ports. Line signaling rate is 10.3125 Gbps at 10GBASE-SR and 25.78125 Gbps at 25GBASE-SR. Reach is 100 m on OM4 and 70 m on OM3, all within the SFP28 SerDes envelope defined by SFP28 MSA SFF-8402.

Optical path is 850 nm VCSEL transmitter, PIN photodiode receiver, TX optical power −5 to +2.4 dBm, RX sensitivity better than −10.3 dBm, 5.3 dB link budget, LC/UPC duplex connector. Digital diagnostics are SFF-8472 compliant, exposing per-module temperature, supply voltage, TX bias, TX power and RX power through SonicOS interface diagnostics. Power dissipation is 0.3 W, the module is hot-swappable, and the operating temperature range is 0 to 70°C commercial. On NSa 6700, the X24-X31 ports are the 25/10/5/2.5GE SFP28 cages that accept the part per SonicWall's firewall documentation.

On FEC, SonicWall NSa 6700 and NSsp 10700/11700/13700 firewalls support IEEE 802.3 BASE-R FEC (Clause 74) on 25G optical SFP28 ports. The platform does not support RS-FEC (Clause 108), which is the default 25G FEC mode on Cisco, Juniper and Arista switches. When connecting a SonicWall firewall to a peer switch over 25G optical SR, set the peer switch FEC mode to BASE-R (Clause 74) or disable FEC negotiation; if the peer remains on Clause 108 RS-FEC, the 25G link will not come up. Reference: SonicWall KB kA1VN0000000I6c0AE. This is a real deployment edge case for mixed-vendor 25G aggregation; confirm the peer switch FEC profile during commissioning.

SonicWall's support policy distinguishes between SonicWall-supplied SFP modules and third-party modules, with the qualified-transceiver table maintained in the SonicWall SFP/SFP+ KB (SonicWall KB kA1VN0000000OlW0AU). At insertion, SonicOS runs an optical-ID check on the EEPROM vendor and part-number strings; modules outside the qualified table may fail that check. The EdgeOptic 02-SSC-8390 compatible is programmed with SonicWall-recognized strings so the ID check returns cleanly on NSa 6700 and NSsp 25G ports.
