FAQ

Questions engineers ask first

How are Cable WM-130/G and Cord Assembly CX-4566/G related?
WM-130/G is the bulk 26-pair (52-conductor) neoprene-jacketed tactical switchboard cable itself. When factory-terminated at both ends with 26-pair hermaphroditic military plugs (U-185/G) and wound onto a field reel (such as 15 m, 38 m, or 76 m / 250 ft lengths), the complete assembly is designated CX-4566/G.
How is WM-130/G used with the J-1077/U distribution box?
In a tactical command post, a 26-pair WM-130/G (CX-4566/G) trunk cable runs from the main telephone switchboard shelter out to a remote J-1077/U binding-post distribution box, where up to 26 individual WD-1/TT field telephone lines fan out to tent/bunker subscribers.
Why does WM-130/G use a thermoset polychloroprene (neoprene) jacket instead of PVC?
PVC stiffens into a rigid rod below -20 °C and shatters when unreeled in arctic weather. Thermoset polychloroprene rubber remains flexible down to -55 °C, resists hot desert sun (+80 °C), and shrugs off JP-8 fuel and tracked-vehicle mud.
Why are there 26 pairs instead of 25 pairs in WM-130/G?
Standard commercial telco trunks have 25 pairs, whereas U.S. military tactical switchboards use 26 pairs: 25 subscriber voice/data pairs plus 1 dedicated order-wire / fault-monitoring pair matching the 52-contact U-185/G connector.
