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 Guia de Seleção
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).

Perguntas mais frequentes e consulta rápida
GYXTZW Armored Fiber Cable FAQ
1. Qual é o principal caso de uso do cabo de fibra retardador de chama GYXTZW?
O GYXTZW é ideal para indoor-outdoor cenários híbridos como building-to-building, substations ou túneis , onde a conformidade com a segurança contra incêndio e a proteção mecânica básica são essenciais.
2. O que torna o GYXTZW diferente dos cabos GYXTW ou GYXTY padrão?
Ao contrário do GYXTW ou GYXTY, o GYXTZW usa uma bainha externa retardadora de chamas que atende aos padrões de proteção contra incêndio ( IEC 60332, etc.), tornando-o adequado para uso em fire-regulated ambientes. Ele também possui armadura de fita de aço para maior resistência ao esmagamento.
3. Qual é a capacidade e estrutura da fibra?
O cabo suporta 2 a 24 núcleos de fibra de modo único G.652D ou G.655 em um uni-tube central cheio de gel bloqueador de água. Dois fios de aço paralelos fornecem resistência à tração, enquanto a fita de aço adiciona proteção.
4. GYXTZW é adequado para enterro direto?
Não é recomendado para sepultamento direto sem conduíte, devido à contagem limitada de núcleos e estrutura mais fina. É melhor usado em dutos, risers, bandejas ou tubulações de proteção, especialmente onde a segurança contra incêndio é uma preocupação.
5. Quais ambientes se beneficiam mais deste cabo?
GYXTZW é perfeito para:
Substations e edifícios de utilidade pública
Indoor-to-outdoor transições de fibra
Túneis de metrô e eixos de cabos
Commercial campi que exigem cabo de chama
