Product Description

LinkFiber currently holds competitively priced 1-core GJYXCH cable with bend-insensitive G.657A1 fiber from China Mobile project stock. Buyers can select a three-steel-wire self-supporting structure—two parallel strength wires plus one messenger—or a customized two-steel-wire flat drop structure. Cable weight, reel length and batch condition can be verified before shipment. Sheath, color, printing, packing and other construction details can be customized.

Key Benefits

  • Current G.657A1 project stock for fast shipment, subject to quantity confirmation.
  • Flat butterfly profile with access grooves for efficient stripping.
  • One-core three-steel-wire version for self-supporting outdoor drops.
  • One-core two-steel-wire version for flat drop applications.
  • PE option for outdoor routes and LSZH option for appropriate indoor sections.
  • Competitive project-stock pricing and verifiable reel/cable weight.
  • OEM printing, reel length, construction and export packing.

  • FTTH links from distribution box or terminal to the building.
  • Villas, apartments, shops, hotels and small offices.
  • MDU/MTU corridors and short indoor routing using the approved sheath.

B2B Procurement Guide

1. Define indoor and outdoor sections

PE and LSZH solve different problems. Identify exposure to sunlight/water, indoor fire requirements, transition points and local code. Do not use one jacket claim for every environment.

2. Choose the fiber and core count

The current stock uses G.657A1 one-core fiber. Confirm the required color, connector/fast-connector compatibility and whether the route needs the three-wire self-supporting or two-wire flat construction.

3. Confirm the support structure

State aerial span, messenger diameter/material, strength-member material and clamp type. The supplier should provide a cross-section drawing before mass production.

4. Control reel and field productivity

Specify reel length, length tolerance, sequential metre marking, drum/carton format and the installer’s handling limits. For high-volume rollouts, request a sample for stripping, connectorization and pull testing.

5. Verify stock-lot claims

For project-surplus stock, request batch number, manufacturing date, stored quantity, storage condition, sample test, certificates and warranty terms. “Ready to ship” should be confirmed on the proforma invoice.

Trust and Related Project Resources

LinkFiber states that it supports samples, OEM/ODM and flexible purchasing on its FAQ. Buyers should still place the exact sample approval, specification and inspection requirements in the order. For a complete FTTH rollout, LinkFiber can consolidate drop cable with fast connectors, terminal boxes, PLC splitters, patch cords, closures, tools and testers; see the one-stop FTTH/FTTx guide.

Standards, Ordering and Customization

  • The construction can be supplied to the applicable YD/T 1997 and IEC 60794-series requirements. CE, RoHS and CPR documents are provided where the exact stock batch or customized model is covered.
  • Standard MOQ: 1 km.
  • Samples: available according to the buyer’s evaluation requirement.
  • Current G.657A1 stock can support fast delivery; normal confirmed-order lead time is 5–10 days, subject to stock quantity and customization.
  • Packing: carton for standard 1 km drop-cable reels or customized wooden drum/carton packing.
  • Fiber type, core count, two-/three-wire structure, sheath, color, print, reel length, weight requirement and packing can be customized.

Request a GJYXCH Sample or Bulk Quote

FAQ
Q:

Why use G.657A1 fiber for FTTH drop cable?

A:
G.657A1 provides bend performance suitable for normal FTTH corners, compact boxes and subscriber premises while maintaining broad compatibility with G.652D networks. The installer must still observe the approved bending radius.
Q:

What is the difference between GJXH and GJYXCH?

A:
GJYXCH normally includes an integrated messenger for self-supporting aerial drops. GJXH is generally the non-messenger flat drop construction. Confirm the drawing because naming and options can vary by supplier.
Q:

How should buyers verify surplus stock?

A:
Request batch identity, manufacturing date, storage information, available quantity, fresh sample test, relevant certificates and written warranty/lead-time terms.
