Citable Specification Notes

Operating temperature: -20°C to +60°C (indoor, per IEC 60794)
Bend radius: 10× cable diameter (dynamic), 5× (static) - G.657A2 fiber
LSZH sheath per IEC 60332-1 and IEC 60754: Supports flame-retardant and zero-halogen indoor cable requirements.
G.657A2 bend-insensitive fiber for tight indoor routing: Recommended for tight bends in indoor FTTH installation.

Product Structure

GJXH is an indoor FTTH drop cable with optical fiber in the center and parallel steel wire strength members on both sides. The LSZH sheath supports protected indoor routing inside buildings, apartments, and subscriber access paths.

Central optical fiberOne or more bend-insensitive fibers are placed in the center for compact indoor FTTH routing.
Parallel steel wire strength membersTwo steel wires provide tensile support during protected indoor installation.
LSZH indoor sheathLow-smoke zero-halogen sheath is suitable for indoor subscriber-side cable routes.

Layer	Component	Material / Function
1	Optical fiber	G.657A1 / G.657A2 / G.652D according to project requirement.
2	Strength member	Parallel steel wires for indoor tensile support.
3	Outer sheath	LSZH sheath for protected indoor routing.
4	Cable profile	Compact indoor drop cable profile for FTTH access routes.

General Optical Performance

Fiber Type	Typical Attenuation	Application Note
G.657A1	≤0.36 dB/km @1310nm; ≤0.22 dB/km @1550nm	Indoor FTTH routes where bend performance is required.
G.657A2	≤0.36 dB/km @1310nm; ≤0.22 dB/km @1550nm	Recommended for tighter indoor bends and subscriber-side routing.
G.652D	≤0.36 dB/km @1310nm; ≤0.22 dB/km @1550nm	Available when project design requires standard single-mode fiber.

Key Features

Indoor FTTH Routing

Designed for protected subscriber-side routes inside buildings, apartments, and indoor distribution paths.

Steel Wire Strength

Parallel steel wires support cable pulling and route stability in indoor installation.

LSZH Sheath

Low-smoke zero-halogen sheath supports indoor use where building safety requirements matter.

Compact Cable Size

Small profile helps with wall routing, conduit paths, and customer-side access installation.

Bend-Insensitive Fiber

Compatible with G.657 series fibers for common indoor FTTH bend conditions.

Project Customization

Fiber count, fiber type, sheath color, packing length, and connector options can be confirmed per order.

Model Comparison

Model	Strength Member	Typical Use	Selection Note
GJXH	Parallel steel wires	Indoor FTTH drop routes	Use when indoor tensile support and compact routing are required.
GJXFH	Parallel FRP	Indoor dielectric drop routes	Use where a non-metallic indoor design is preferred.
GJXV	Steel wire / indoor drop design	Protected indoor subscriber routes	Confirm drawing and sheath requirement before selection.
GJYXCH	Messenger wire	Outdoor self-supporting FTTH access	Use for aerial drop routes requiring self-supporting installation.

Application Scenarios

FTTH Subscriber Drop

Protected indoor route from the distribution point to customer premises equipment.

Apartment Distribution

Indoor routing for apartments, MDU buildings, and protected shared spaces.

Building Entry

Building-side indoor routing after the access cable enters the premises.

Wall Box Connection

Short indoor connection between wall boxes, distribution boxes, and termination points.

Protected Indoor Path

Protected subscriber-side pathways where exposed outdoor performance is not required.

Custom Indoor Route

Used where the project drawing calls for compact indoor FTTH cable routing.

When to Select GJXH Instead of a Similar FTTH Drop Cable

GJXH is the indoor choice when the subscriber-side route is protected and the approved design permits parallel steel strength members. Confirm that the cable will be installed after building entry or in another protected path, then verify the required fiber, LSZH sheath, cable profile, routing length, and termination method. Do not use the indoor designation alone to approve an exposed pole-to-building route.

Choose GJXH when

The route is an indoor FTTH drop path and the drawing calls for compact cable construction with steel-wire tensile support.

Review another model when

A non-metallic indoor construction points to GJXFH; a self-supporting outdoor aerial section points to GJYXCH or GJYXFCH after the route and support requirement are confirmed.

Approve before production

Confirm the route boundary, steel-member requirement, fiber type, sheath requirement, marking, drum or coil length, and the connector or splice termination plan.

FAQ About GJXH Indoor FTTH Drop Cable

Q: What is GJXH used for?

GJXH is used for protected indoor FTTH drop routes, building-entry sections, apartment distribution, and subscriber-side routing. Final use should follow the project drawing and indoor route conditions.

Q: What is the strength member of GJXH?

GJXH uses parallel steel wire strength members in its indoor drop cable structure. Final construction should be confirmed from the drawing and project specification before production.

Q: What fiber types are available?

G.657A1, G.657A2, or G.652D fibers can be reviewed according to the project requirement. G.657 series fibers are commonly used where bend performance matters in indoor routing.

Q: What is the difference between GJXH and GJXFH?

GJXH uses parallel steel wire strength members, while GJXFH uses parallel FRP strength members. The final selection should follow the required cable drawing, sheath material, and installation route.

Q: Can GJXH be used outdoors?

GJXH is intended for indoor or protected building routes. For exposed outdoor aerial routes, review outdoor self-supporting drop cable models such as GJYXCH or GJYXFCH.

Q: What should I send for quotation?

Send the drawing if available, fiber count, fiber type, sheath material, color, route type, packing length, quantity, and any connector or labeling requirement.
