our company

30+ years

Our factory was found in 1992, first start with coaxial cable which was one of the biggest manufacturers in lin'an city.In year of 2001 started focusing on the production of optical cables.

30+ countries

In year of 2008, set up international sales department and have long-term cooperation with more than 30 countries and have 18 years` rich experience to export cables .

Model Definition GYTC8S

GY: Outdoor communication optical cable

T: Gel-filled construction

C: Layer-stranded structure

8: Figure-8 dual-unit integrated sheath

S: Galvanized steel strand messenger wire

Full name: Metal central strength member, loose tube layer-stranded gel-filled, PSP steel tape armored, figure-8 self-supporting outdoor aerial optical cable

Standard Technical Specifications

Fiber count: 4/8/12/24/36/48/72/96/144 cores

Standard fiber: G.652D (FTTH & metropolitan access network)

Typical attenuation: ≤0.36dB/km @1310nm; ≤0.22dB/km @1550nm

Overall dimension: 9.0×14mm ~ 16.8×25.5mm (varies with fiber count)

Weight: 160~350kg/km

Installation method: Exclusively for self-support aerial laying, not for duct or direct burial

Internal Layer Structure (Integrated Figure-8 Dual Cavity)

Two independent cavities extruded within one unified black PE outer sheath.

PBT loose tube

Loose tubes filled with waterproof gel, fiber excess length eliminates tensile stress

SZ layer stranding

Loose tubes and filler rods stranded around central steel wire, fully filled with water-blocking gel

Corrugated steel tape

Longitudinal PSP coated steel tape Moisture barrier, anti-crush & rodent protection

Central steel strength wire

Single galvanized steel wire for core compression resistance

Self-support Messenger Unit

Multi-strand galvanized steel wire integrated as load-bearing messenger, no separate overhead steel wire required.

Outer Sheath

Black HDPE sheath, UV-resistant & anti-aging for long-term outdoor exposure.

Key Product Features

Integrated load-bearing messenger, simplified installation

Fig 8

The figure-8 all-in-one design eliminates separate messenger wire erection, cutting construction cost & duration; ideal for rural & residential FTTH aerial wiring.

Water blocking

Triple water-blocking system for superior moisture resistance Tube gel + core filling gel + steel tape barrier prevents water penetration in rainy & humid mountain areas.

Outstanding mechanical performance

Long-term allowable tensile load: 2000~4500N; short-term breaking load: 5000~11200N

Armor

Steel tape armor delivers strong crush resistance & rodent deterrence

Wide temperature

Adaptability for outdoor use Operating range: -40℃ ~ +70℃; UV-stabilized PE sheath withstands long-term sunlight exposure & extreme temperature fluctuation.

Stress-free fiber protection

Controlled fiber excess length inside loose tubes prevents attenuation rise caused by wind sway or thermal expansion & contraction.

Key advantage

less cost

Built-in messenger wire removes separate steel wire erection, greatly lowering aerial construction cost.

less loss

Steel tape armor provides waterproof & rodent-proof performance for long outdoor service life.

less Time

Layer-stranded loose tube design supports high fiber counts for backbone transmission

Package of GYTC8S

We have three types of packing for your reference.

Wooden drum

The original wood drum packaging is the most robust and durable option; it is suitable for heavy cables of this type and provides excellent protection for the optical cable.

Composite Drum

Plywood composite drum are also sturdy and durable and suitable for countries requiring fumigation, yet they are cost lower than fumigated wooden pallets.

Fumigated Wooden Drum

Fumigated wooden pallets are suitable for clients with high requirements, but the price.
