Covers the physical media used for railway telecommunication — overhead open-wire lines (largely legacy), underground cables, Quad cable, and OFC (Optical Fibre Cable) — and the parameters and limitations specific to each, including special considerations for communication in electrified (RE) areas.
Key Points
- Communication cables in electrified (RE) areas require specific protective measures against induced voltage from the overhead traction supply.
