CPAC-TR-1SX-D-BCC | Checkpoint Compatible 1GB Multi-Mode 550m (1000BASE-SX)

Q: Will this work in place of the Checkpoint CPAC-TR-1SX-D?
A: Yes. This transceiver is built to the same 1000BASE-SX standard, uses an identical SFP form factor, operates at 850nm wavelength, and supports the same 1.25Gbps data rate. It is plug-and-play compatible with Checkpoint appliances that specify the CPAC-TR-1SX-D.

Q: Which Checkpoint appliances support this transceiver?
A: The CPAC-TR-1SX-D is officially supported on Checkpoint 25XX, 3970, 3980, 9000, 19000, and 29000 series appliances when used with the CPAC-8-1/10F-D network interface card. Verify your appliance model has SFP or SFP+ ports before ordering.

Q: What is the actual reach on OM3 and OM4 fibre compared to OM2?
A: All three cable grades support the full 550m distance specified for 1000BASE-SX. OM3 and OM4 have lower attenuation and higher bandwidth than OM2, but at 1Gbps speeds the reach is identical. The difference becomes significant only at 10Gbps and above.

Q: Can I mix this with OEM Checkpoint transceivers in the same appliance?
A: Yes. The transceiver follows SFP MSA and IEEE 802.3z standards, so it operates identically to the OEM part. You can populate some ports with BCC modules and others with Checkpoint or other vendor modules without compatibility issues.

Q: Does DOM monitoring work through the Checkpoint management interface?
A: Yes. The transceiver implements SFF-8472 digital diagnostics, which Checkpoint GAiA and management platforms query via the standard I2C interface. You will see real-time optical power, temperature, and voltage readings just as you would with the OEM transceiver.
