Direct Buried Cable

  • GYFTZY63 Rodent-Resistant Flame-Retardant Direct Buried Cable

Product Description

The structure of GYFTZY63 optical cable is formed by encasing $250 ext{ }\mu ext{m}$ optical fibers 

into PBT loose tubes filled with a waterproof compound. The center of the cable core is a non-metallic 

central strength member, and the interstices within the core are filled with water-blocking compound. 

The loose tubes (and filler rods) are stranded around the central strength member to form a compact, 

circular core. A inner sheath layer is extruded over the core, followed by glass yarn placed outside 

the inner sheath as a rodent-proof material, and finally extruded with a layer of flame-retardant outer jacket.

Product Features

Excellent Mechanical & Temperature Performance: Superior physical strength and reliable stability across wide 

operating temperature ranges.

Effective Rodent Protection: Specially incorporated glass yarn design effectively prevents damage to 

the optical cable caused by rodents.

Hydrolysis-Resistant Loose Tube: High-strength PBT loose tube material exhibits excellent hydrolysis 

resistance and mechanical strength.

Superior Water-Blocking Performance: Premium waterblocking material prevents longitudinal water ingress 

along the cable

Special Jelly Protection for Fibers: Loose tubes are filled with special compound jelly to provide critical, 

long-term protection for the optical fibers.

Flame-Retardant Safety: Flame-retardant outer jacket enhances safety for critical direct burial 

and duct installations.

Frequently Asked Questions

What is the Rodent-resistant, flame-retardant, direct-buried optical cable (GYFTZY63) used for?

Huifiber GYFTZY63 is a non-metallic, rodent-resistant, flame-retardant optical cable with glass yarn armor and PBT loose tubes.

Can Huifiber customise the Rodent-resistant, flame-retardant, direct-buried optical cable (GYFTZY63)?

Yes. Huifiber supplies cable under the buyer's own brand as well as under the Huifiber brand. Fibre count, jacket material, jacket print, drum marking, drum length, packaging and datasheet layout can all be produced to the customer's requirement, and the engineering team can work from a customer specification or adapt an existing construction to a new route requirement.

How is the Rodent-resistant, flame-retardant, direct-buried optical cable (GYFTZY63) tested before shipment?

Every production batch is tested before it leaves the plant in Dongguan. Attenuation and geometry are measured on OTDR and optical bench equipment, and mechanical performance is verified against the datasheet for the construction. A factory test report is issued with each shipment, so an incoming inspection can be checked against the same numbers.

What should I send for a Rodent-resistant, flame-retardant, direct-buried optical cable (GYFTZY63) quotation?

Send the fibre count and fibre type, the jacket material or fire rating, the route length or span and the drum length you need, the destination port or country, and any certification or test-report requirement. With those details the sales engineer can confirm the construction and return a quotation with an indicative lead time.
