M24643/59-04UO LSC5OSW-4

When shipboard communications demand both network performance and survivability, M24643/59-04UO (LSC5OSW-4) provides a military-qualified Category 5e Ethernet cable solution engineered specifically for naval environments. Associated NSN: 6145-01-525-5216. Manufactured to MIL-DTL-24643 requirements, LSC5OSW-4 combines commercial Cat5e data transmission performance with low smoke, low toxicity shipboard cable construction required for modern Navy platforms. Unlike commercial Ethernet cable, this shipboard-rated construction uses low smoke zero halogen (LSZH) materials designed to reduce smoke generation and eliminate halogen emissions during fire events—helping improve personnel safety and protect mission-critical systems aboard naval vessels. The watertight water-blocked construction helps prevent moisture ingress in harsh marine environments, while the foil and braid shield design provides strong EMI/RFI protection for reliable signal integrity in electrically noisy shipboard applications. LSC5OSW-4 consists of four 24 AWG twisted pairs and is commonly specified for: Shipboard LAN and Ethernet networks Combat systems and C5ISR infrastructure Machinery control and monitoring systems Internal communications networks Naval data distribution systems As part of the MIL-DTL-24643 low smoke shipboard cable family, M24643/59-04UO supports the Navy’s transition away from legacy PVC-based cable systems toward safer, lower-toxicity, and reduced-smoke shipboard cabling technologies. For shipyards, naval integrators, defense contractors, and procurement teams, LSC5OSW-4 delivers a specification-driven Cat5e shipboard cable solution designed for demanding military marine environments.
