Check Point CPAC-TR25SR-ADP Compatible 25GBASE-SR SFP28 with QSFP28 Adapter for Maestro MHO-140 and MHO-175

EdgeOptic's CPAC-TR25SR-ADP compatible is a Check Point-coded 25GBASE-SR SFP28 transceiver built as a direct replacement for the Check Point CPAC-TR25SR-ADP. The -ADP suffix designates the adapter-equipped variant: the module ships as a 25GBASE-SR SFP28 with a QSFP28-to-SFP28 mechanical adapter that allows the module to seat in QSFP28 cages on Check Point Maestro platforms in addition to native SFP28 sockets on compatible NICs. It ships with Check Point-recognized EEPROM so Maestro HyperScale Orchestrators and the CPAC-2-100/25F-B NIC identify the optic as a native Check Point part.

Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber: 100m on OM4, 70m on OM3. Line signaling rate is 25.78125 Gbd, single-rate, per IEEE 802.3by Clause 112. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, link budget 5.3 dB with host RS-FEC per IEEE 802.3by Clause 108. Duplex LC/UPC, DOM per SFF-8472, 0.3W typical power. Operating case temperature is 0 to 70 degrees Celsius.

Per the Check Point Appliance Accessory Guide, the CPAC-TR25SR-ADP variant operates on Check Point Maestro HyperScale Orchestrator MHO-140 (R81.20 and later), Maestro HyperScale Orchestrator MHO-175 (R81.20 and later) and the CPAC-2-100/25F-B NIC. The adapter-equipped -ADP variant is specifically not supported on the CPAC-2-40/100F-C NIC. The non-adapter CPAC-TR-25SR-D variant is a separate Check Point ordering code that covers MHO-140 in native SFP28 mode only and does not carry the QSFP28 adapter; CPAC-TR25SR-ADP is the broader-platform-coverage variant of the two.

On Check Point Maestro and Check Point NIC platforms the optical validation path runs a module identification check against the vendor and part-number EEPROM strings at insertion. The EdgeOptic compatible carries the Check Point strings that the validation path expects, so on standard R81.20 and later images the module is accepted on the default acceptance path. Check Point's official support policy is that only Check Point-supplied SFP transceivers are covered under Check Point support contracts; third-party modules are not covered under that policy even when functionally operational. Teams operating under strict support-contract regimes should review the module policy with their Check Point account team before deployment. Environments running hardened asset-inventory policies can request the exact EEPROM vendor and PN strings from EdgeOptic for allowlist entry.

On FEC, the optical path is agnostic to the host FEC mode. 25G FEC is configured on the MAC layer at each link partner. In typical Maestro-to-switch 25G uplinks and CPAC-2-100/25F-B NIC-to-switch links, RS-FEC per IEEE 802.3by Clause 108 is the default path and is the mode this module is specified against. Clause 74 Fire Code FEC (BASE-R) and no-FEC are supported at the optical layer where both link partners are configured for that FEC profile. DOM registers for transmit power, receive power, supply voltage, laser bias current and module case temperature are accessible through standard SFF-8472 reads on the Maestro HyperScale management interface and on any EEPROM-aware link partner. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112 before dispatch.
