A new range of Fibre reinforced rod Telerod BA has been developed addressing the requirement of Optical Fibre Cable manufacturers for strength members having better performance in the 0 to 0.75 % strain range. The advantages over conventional glass rods are:

Advantages

1. Higher Y Modulus
2. Higher strength for same cross-section.
3. Higher strength for same weight of rod
4. Better FASE 0.5
5. Lower co-efficient of linear expansion
6. Cost effective

Disadvantages

1. Elongation at yield 2.5% (lower then Telerod G)
2. Ultimate tensile strength (lower then Telerod G)
