Check Point CPAC-TR-1LX-C Compatible 1000BASE-LX SFP

EdgeOptic's CPAC-TR-1LX-C compatible is a Check Point-coded version of the EdgeOptic 1.25G-SFP-20D multi-vendor 1000BASE-LX 20 km transceiver. Check Point catalogs the CPAC-TR-1LX-C as a 10 km 1000BASE-LX SFP in the Check Point Appliance Accessory Guide; the EdgeOptic compatible covers the full 20 km reach class of the underlying 1.25G-SFP-20D platform, so it qualifies for both the OEM 10 km Check Point appliance use case and extended-reach 20 km Check Point gateway deployments on a single coded build.

The optical side follows IEEE 802.3z 1000BASE-LX on 9/125 µm single-mode fiber via duplex LC connectors at 1310 nm, with a 1260 to 1360 nm wavelength band. Transmit power is −9 to −3 dBm and receiver sensitivity is −24 dBm with a −3 dBm overload limit, giving 15 dB of link budget that extends practical reach to 20 km on standard G.652 fiber. The transceiver runs Gigabit Ethernet at 1.25 Gbps, draws power from a +3.3 V single supply, and exposes DDM/DOM telemetry so Check Point gateway monitoring can read live TX power, RX power, bias current, supply voltage, and module temperature.

When sourcing a Check Point single-mode 1G SFP, confirm the trailing suffix on the original ordering code. This page covers the CPAC-TR-1LX-C specifically. The CPAC-TR-1LX-D is a separate Check Point ordering code with its own appliance qualification; the CPAC-TR-1SX-C is the 850 nm multimode 550 m variant for short-reach in-rack runs. Check the Check Point Appliance Accessory Guide for the authoritative platform-by-platform SFP support list when fitting transceivers into Check Point Security Gateways, Quantum, and Maestro chassis.

This CPAC-TR-1LX-C compatible is one EEPROM build of the EdgeOptic 1.25G-SFP-20D platform, a single 1000BASE-LX 1310 nm 20 km SMF transceiver that ships under multiple vendor codings. The hardware is INF-8074i SFP MSA compliant, hot-pluggable, CE marked, RoHS compliant, and Class 1 laser safe per IEC 60825-1 and FDA 21 CFR 1040, so the EdgeOptic catalog covers the same optical build under Cisco, Juniper, Arista, HPE, Hirschmann, PLANET, Brocade, and other vendor ordering codes for 1000BASE-LX 20 km SMF.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For Check Point appliance fit checks, mixed CPAC variant sourcing, or volume quotes, contact our sales team.
