CPAC-TR-1LX-D-BCC | Checkpoint Compatible 1GB Single-Mode 20km (1000BASE-LX)

Q: Will this work in place of the Checkpoint CPAC-TR-1LX-D?
A: Yes. This module is functionally identical to the CPAC-TR-1LX-D. It conforms to the same 1000BASE-LX standard, operates at 1.25 Gbps over 1310nm single-mode fiber, and uses the SFP form factor with duplex LC connector. It is plug-and-play compatible with Checkpoint security appliances that support the original transceiver.

Q: Which Checkpoint appliances support this transceiver?
A: This module is compatible with Checkpoint 9000 series, 19000 series, and 29000 series security gateway appliances, as well as Maestro MHO140 systems. It works with interface cards that provide SFP ports, including the CPAC-8-1/10F-D (8-port 1/10GbE SFP+) and CPAC-4-10/25F-D (4-port 10/25GbE SFP28). Verify your appliance has an available SFP or SFP+ slot; 1GB SFP modules operate in both 1GbE SFP and 10GbE SFP+ ports.

Q: What type of fiber and connectors does this module require?
A: This transceiver requires single-mode fiber with 9/125 µm core/cladding diameter, terminated with duplex LC/UPC connectors. For maximum reach, use OS2-grade single-mode fiber with attenuation around 0.4 dB/km. OS1 fiber (typically 1 dB/km) is acceptable for shorter runs. The module transmits and receives at 1310nm, so both fiber strands operate at the same wavelength. Ensure TX on one end connects to RX on the far end.

Q: Does this module support 20km reach on all fiber types?
A: The 20km specification assumes low-loss OS2 single-mode fiber and clean, properly terminated LC connectors. Actual reach depends on total link loss budget: this module provides approximately 10-11 dB of optical budget, which supports 20km over OS2 fiber (0.4 dB/km) plus connector and splice losses. Higher-loss OS1 fiber or dirty connectors will reduce maximum distance. Use the DOM function to monitor received signal strength and verify adequate margin on installed links.

Q: Can I access DOM data on Checkpoint appliances running Gaia OS?
A: Yes. Checkpoint Gaia OS exposes SFP diagnostic data through the command-line interface and can be queried via SNMP. Use CLI commands to read TX/RX power, temperature, and voltage from the transceiver's internal sensors. This data is valuable for monitoring link health, identifying marginal optical power levels before a failure occurs, and verifying that both ends of a link are operating within specification. Refer to Checkpoint documentation for the specific CLI syntax for your Gaia release.
