New Hybrid Composite Cable for Power Transmission,Critical Signaling, Telecom Application

摘要

Need of telecommunication industries of power transmission along with data transmission is increasing, which felt the need to explore the innovative product category called Hybrid Cable. Hybrid aerial, Underground cable is very innovative and versatile cabling solution with in built power transmission required for network equipments with OFC cables. Hybrid Composite Cable is need of a day, firstly to support for Power transmission for always ON (Interrupt free) telecom needs. The telecom network elements & terminations are powered with help of this copper pair. Secondly, the Copper pair also used for critical signaling needs for railway signaling & fiber optic element for Telecom application. In this paper we described the hybrid cable of Quad & OFC for railway signaling and communication. Conventionally railway use quad cables for communication as well as signaling. Due to change in technology & increase in applications of communications for data transmission optical fiber cables are now become backbone of communication. Customer / Passenger expectations are increased for communications during traveling. On other hand railways are forced to provide services with lower investments. Railways have no choice to select only one communication media due to application & limitations of each media. New hybrid cable design is made such that it reduces cost of installation & total cost of two separate cables. The Copper conductors & types of fiber cable reinforcement & protection are provided based on requirement of the field.
