How to chioce between GYXTC8S, GYTC8S, and GYTS Fiber Cables ?

The choice among GYXTC8S, GYTC8S, and gyts depends primarily on fiber count requirements, installation environment, mechanical stress, and budget constraints—particularly installation labor costs.

1. Choose GYXTC8S (Central Tube Figure‑8) when:

Fiber count is low (≤24 cores) – typically for access networks, FTTH distribution, or short‑haul links.

Maximum mechanical strength is required – its 3000‑4000 N tensile strength and 3000 N/100mm crush resistance make it the most rugged option among the three. Ideal for harsh environments, long spans, or areas with heavy wind/ice loads.

Installation speed and cost savings are top priorities – the integrated steel strand reduces installation time and labor by approximately 30% compared to non‑self‑supporting designs. A single crew can deploy 3‑4 km per day.

Weight is not a major concern – at ~140‑245 kg/km, it is significantly heavier than GYTC8S and GYTS, which may affect shipping costs and pole loading.

Best for: Rural FTTH backbones, harsh climate aerial routes, and projects requiring high mechanical durability with low fiber counts.

2. Choose GYTC8S (Stranded Figure‑8) when:

Fiber count ranges from 24 to 144 cores – the stranded loose tube design supports higher fiber density, making it suitable for metropolitan networks and aggregation links.

A balance between fiber capacity and installation cost is needed – it retains the self‑supporting advantage (integrated messenger) for fast aerial deployment, while offering more cores than GYXTC8S.

Moderate mechanical performance is acceptable – with 1500 N tensile and 1500 N/100mm crush resistance, it handles standard aerial conditions but is less robust than GYXTC8S.

Weight is a critical factor – at ~94 kg/km (12‑core reference), it is roughly 30‑50% lighter than GYXTC8S, reducing transport and pole loading costs.

Best for: Urban/metro networks, medium‑span aerial routes, and projects requiring higher core counts without sacrificing installation efficiency.

3. Choose GYTS (Stranded Steel Tape Armored) when:

Installation is not purely aerial – GYTS lacks a built‑in messenger, so it is best suited for duct, conduit, or direct burial applications. For aerial use, it requires a separate steel messenger line, adding material and labor costs.

Budget is extremely tight on cable material – GYTS has lower material cost than figure‑8 designs. However, total project cost may be higher when accounting for additional messenger hardware and slower installation (20‑40% higher installation cost than figure‑8 types).

Fiber capacity is high (up to 144 cores) and mechanical protection is still required – the PSP steel tape armor provides rodent and crush protection suitable for underground or duct environments.

Weight is a constraint – at ~78‑105 kg/km, it is lighter than GYXTC8S but comparable to GYTC8S.

Best for: Mixed aerial‑duct‑burial routes, projects with existing messenger infrastructure, or when installation labor is inexpensive and material cost is the primary driver.

Final Engineering Recommendation

If fiber count ≤24 and mechanical durability is critical → GYXTC8S is the premium choice for fast, reliable aerial deployment in challenging environments.

If fiber count >24 and aerial installation efficiency is still important → GYTC8S offers the best balance of core capacity, weight, and installation cost.

If the route is primarily duct/burial, or if separate messenger infrastructure already exists → GYTS provides a cost‑effective armored solution, but total project cost may exceed figure‑8 alternatives when aerial installation is required.

Cost‑saving tip: For aerial‑only projects, the 30% installation cost reduction of figure‑8 designs often outweighs the slightly higher cable material cost, making GYXTC8S and GYTC8S more economical over the full project lifecycle.
