CPAC-TR-10SR-D-BCC | Checkpoint Compatible 10GB Multi-Mode 300m (10GBASE-SR)

Q: Will this work in place of the Checkpoint CPAC-TR-10SR-D?
A: Yes. The CPAC-TR-10SR-D-BCC is a plug-and-play replacement for the Checkpoint CPAC-TR-10SR-D. It matches the SFP+ form factor, 10GBASE-SR standard, 850nm wavelength, and 10.3 Gbps data rate of the original module, and is programmed with the correct EEPROM coding to be recognized by Checkpoint Gaia OS without requiring manual override or configuration changes.

Q: Which Checkpoint appliances support this transceiver?
A: This module is designed for Checkpoint security appliances with 10GbE SFP+ ports supporting 10GBASE-SR. The CPAC-TR-10SR-D series is listed in the Checkpoint Appliance Accessory Guide for appliances including the 9000, 19000, and 29000 series, as well as certain QSFP28 adapter configurations (CPAC-TR-10SR-D-ADP). Always verify the specific appliance model against the current Checkpoint Accessory Guide before deployment, as supported transceiver lists vary by appliance generation.

Q: What fibre type and reach does this transceiver support?
A: This transceiver supports multi-mode fibre (MMF) with 50/125 micron core/cladding. Maximum reach is 300m over OM3 fibre (2000 MHz·km modal bandwidth) and extends to 400m over OM4 fibre (4700 MHz·km modal bandwidth). The 850nm VCSEL wavelength is optimized for short-reach multi-mode links; do not use this module with single-mode fibre or attempt long-reach connections beyond the OM3/OM4 specifications.

Q: Does this module support Digital Optical Monitoring?
A: Yes. DOM support is implemented via the SFF-8472 two-wire serial interface. You can read real-time diagnostics including transmit optical power, receive optical power, module temperature, supply voltage, and laser bias current. Checkpoint Gaia OS exposes these parameters through CLI and SNMP, allowing you to monitor link health, troubleshoot power budget issues, and set threshold alarms for proactive fault detection before link failure occurs.

Q: Can I mix this transceiver with 1 Gigabit Ethernet on the same link?
A: The transceiver supports multi-rate operation from 1.25 to 10.3 Gbps, covering both 1GbE and 10GbE data rates. However, link speed negotiation depends on the host appliance port configuration and the far-end device capabilities. If the Checkpoint appliance SFP+ port is configured for 10G operation, both ends of the link must operate at 10G; you cannot auto-negotiate down to 1G on a 10G-only port. Verify port speed settings in Gaia OS before assuming multi-rate compatibility on a specific appliance interface.
