How to Choose Optical Fiber Cable for Railway & Telecom – EcomTelco
Introduction
Choosing the correct optical fiber cable is crucial for the success of large-scale infrastructure projects like railways, metro networks, smart cities, and telecom expansions. With a wide range of cable types available in the market, it’s essential to pick one that meets your project’s technical, environmental, and compliance needs.
In this guide, we’ll help you understand what to look for when selecting the right fiber cable.
Understand Your Project Needs
Different projects require different specifications:
Application | Recommended Cable Type |
---|---|
Railway trackside | Armoured, Gel-Filled Cable |
Overhead / Aerial use | ADSS (All-Dielectric Self-Supporting) |
Underground ducts | HDPE Sheathed Loose Tube Cable |
Tunnel / harsh terrain | FRP Reinforced Optical Fiber |
For Indian Railways, armoured single-mode loose tube cables are standard.
Check Technical Specs
Look for the following specs before finalizing a cable:
Fiber Type: Single-mode (SM) or Multi-mode (MM)
Core Count: 6, 12, 24, or 48 Core – depending on data need
Attenuation: Typically <0.35 dB/km at 1310nm
Jacket Material: HDPE, LSZH, or FRLS (fire-safe cables)
Operating Temperature: -20°C to +70°C for India zones
All cables at EcomTelco are tested with OTDR and compliant with RDSO/TEC.
Installation Environment
Before purchase, ask:
Will the cable be buried directly or inside ducts?
Is rodent protection needed?
Is there high EMI (electromagnetic interference)?
If yes, opt for armoured or metallic reinforced cables.
Compliance & Certification
Always demand:
RDSO approval (for Indian Railways)
TEC certification (for telecom)
Test reports – OTDR, tensile strength, and crush resistance
EcomTelco provides compliance-ready cables with documentation.
Delivery, Warranty & Support
Choose a vendor that offers:
Fast shipping (Pan India)
Minimum 12-month warranty
After-sales support (installation help, connectors, splicing)
