Mil-Spec Military part number MIL-DTL-24643/31 has two cable-type designations: LS2SU and LS2SUS. This shipboard telephone cable is rated for 600 volts and uses Telephone Identification Code by Method 3. The M24643/31 LS2SU and LS2SUS Shipboard Cable is a low-smoke, zero-halogen shipboard cable. It is suitable for non-watertight, non-flexing service. This Mil-Spec cable features paired stranded bare copper conductors, Cross-Linked Polyethylene (XLPE) insulation, and an LSZH cross-linked Polyolefin (XLPO) jacket. This cable also has individually shielded conductors. This cable is suitable for use in shipboard combat systems, interior communications, lighting, and power applications that do not exceed 600V. The Mil-DTL-24643 Mil-Spec covers cables suitable for use in shipboard, communications, instrumentation, and electronic applications.
In the cable designation for LS2SU, the letters LS refer to low smoke and halogen-free cable, 2 refers to twisted pairs, A refers to overall shielding, and U refers to the fact that the cable is unarmored.
In the cable designation for LS2SUS, the letters LS refer to low smoke and halogen-free cable, 2 refers to twisted pairs, A refers to overall shielding, U refers to the fact that the cable is unarmored, and S refers to a double overall shield.

Non-watertight
Thermoset insulation is ideal for settings where durability and stiffness are essential
LSZH jacket is fire resistant and emits low smoke, which is ideal for shipboard settings which often have restricted ventilation
LSZH jackets also emit low acid, gas, and toxicity when subjected to fire, maintaining circuit integrity
Shielded cables tend to reduce electrical noise created by electromagnetic signals in the cable while also providing greater protection and durability compared to unshielded cables.
