What is GYXTZW optical cable
GYXTZW optical cable is an outdoor armored optical cable that adopts a central tube structure, filled with waterproof grease, longitudinally wrapped with plastic-coated steel tape (PSP) and embedded with parallel steel wires as reinforcement, while using low-smoke, halogen-free flame-retardant (LSZH) material for the outer sheath. It combines excellent resistance to lateral pressure and tensile performance with flame-retardant, low-smoke, and halogen-free characteristics, and is widely used in subways, tunnels, chemical plants, and other scenarios with high fire safety requirements.

GYXTZW Armored Fiber Cable Guide de sélection
Fire-retardant cable engineering selection between GYXTZW and GYXTW/GYXTY/GYTS:
GYXTZW features steel tape armor combined with an LSZH (Low Smoke Zero Halogen) outer sheath, providing both mechanical protection and flame retardancy. It is specifically designed for outdoor installation scenarios that also require fire safety, such as cable entry sections into buildings, tunnels, subways, power plants, chemical plants, and other confined spaces where low smoke and halogen-free properties are mandatory. GYXTW, GYXTY, and GYTS all use PE sheaths which are UV-resistant and suitable for long-term outdoor exposure, but they are not flame-retardant and should never be used indoors or in fire-sensitive areas.
Fire safety and entry section requirements:
For core network entry sections (typically ≥500 meters per segment) into equipment rooms, central offices, high-rise buildings, tunnels, and other fire-rated spaces, GYXTZW with LSZH sheath is the mandatory choice. The LSZH material produces minimal smoke and no toxic halogen gases when burned, ensuring personnel safety and equipment protection in confined spaces. Standard GYXTW, GYXTY, and GYTS with PE sheaths are strictly for outdoor use only – they will burn and produce dense smoke if exposed to fire, failing building code requirements for indoor/plenum areas.
Non-flame-retardant cable applications:
GYXTW is a classic "central tube armored outdoor cable" – its PE sheath provides excellent UV resistance and long-term outdoor reliability, with steel tape armor offering good crush and rodent protection. However, it cannot be used in fire-sensitive spaces. GYXTY is the most economical option for low-core-count aerial or duct installations where mechanical stress is minimal and fire safety is not a concern – its lack of steel tape armor makes it unsuitable for direct burial or rodent-prone areas. GYTS, with its stranded loose tube design, supports much higher fiber counts (up to 288 cores or more) and offers superior mechanical strength for trunk lines and long-haul backbone networks, but it also lacks flame retardancy. For applications requiring both high mechanical strength and flame retardancy, a GYTZS (stranded, steel tape armor, LSZH) variant would be the appropriate choice.
GYXTZW Optical Cable – Brief Installation Instructions
Cable Handling – Avoid twisting or crushing. Do not exceed the rated tensile load (typically 600N short term, 300N long term).
Bending Radius – Maintain min. bending radius of 10× cable OD during installation, 20× during pulling.
Pulling – Use a pulling grip or friction-type pulling eye attached to the strength members (parallel steel wires + PSP tape).
Stripping – Remove the LSZH sheath and PSP tape carefully. Do not nick the loose tube or fibers.
Grounding – The steel wires and PSP are metallic; ground them properly at one end if required.
Flame Retardant Note – The LSZH sheath provides low smoke & halogen-free protection; avoid excessive heat during termination.
Installation Types – Suitable for aerial, duct, or direct burial (with extra protection if needed).

Foire aux questions et enquête rapide
GYXTZW Armored Fiber Cable FAQ
1. Quel est le cas d'utilisation principal du câble fibre ignifuge GYXTZW?
GYXTZW est idéal pour indoor-outdoor scénarios hybrides tels que building-to-building, substations ou , où la conformité en matière de sécurité incendie et la protection mécanique de base sont toutes deux essentielles.
2. Qu'est-ce qui différencie GYXTZW des câbles GYXTW ou GYXTY standard?
Contrairement à GYXTW ou GYXTY, GYXTZW utilise une gaine extérieure ignifuge qui répond aux normes de protection contre les incendies (IEC 60332, etc.), ce qui la rend appropriée pour une utilisation dans des environnements fire-regulated . Il dispose également d'un blindage en ruban d'acier pour une résistance accrue à l'écrasement.
3. Quelle est la capacité et la structure de la fibre?
Le câble prend en charge 2 à 24 cœurs de fibre monomode G.652D ou G.655 dans un tube uni central rempli de gel bloquant l'eau. Deux fils d'acier parallèles fournissent une résistance à la traction, tandis que le ruban d'acier ajoute une protection.
4. GYXTZW convient-il à l'inhumation directe?
Il n'est pas recommandé pour un enfouissement direct sans conduit, en raison du nombre limité de noyaux et de la structure plus mince. Il est mieux utilisé dans les conduits, les colonnes montantes, les plateaux ou les tuyauteries de protection , en particulier lorsque la sécurité incendie est un problème.
5. Quels environnements bénéficient le plus de ce câble?
GYXTZW est parfait pour :
Substations et bâtiments utilitaires
Indoor-to-outdoor transitions de fibres
Tunnels de métro et puits de câbles
Commercial campus nécessitant un câble ignifuge
