Product Structure

GJYXCH outdoor self-supporting FTTH drop cable structure

GJYXCH is an outdoor self-supporting FTTH drop cable with a figure-8 profile and steel messenger wire. It is designed for short outdoor subscriber drop routes, pole-to-building access, and last-mile FTTH connections where the cable needs its own support member.

Central optical fiberBend-insensitive fiber supports outdoor-to-building FTTH drop routing and subscriber access paths.
Steel messenger wireThe messenger provides self-supporting strength for short aerial drop installation.
Outdoor sheathOutdoor jacket protects the drop cable body in exposed access routes before building entry.

Layer	Component	Material / Function
1	Optical fiber	G.657A1 / G.657A2 / G.652D according to project requirement.
2	Drop cable body	Bow-type FTTH drop cable body for subscriber-side access.
3	Messenger wire	Steel messenger for self-supporting short aerial drop routes.
4	Outer sheath	Outdoor sheath for pole-to-building and access network installation.

General Optical Performance

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

Key Features

Self-Supporting Drop Route

Steel messenger supports short outdoor aerial drop routes from pole or terminal point to building entry.

FTTH Last-Mile Access

Designed for subscriber-side outdoor access connections in residential and small commercial FTTH networks.

Figure-8 Profile

Integrated messenger and drop cable body simplify short aerial FTTH drop installation.

Bend-Insensitive Fiber

Compatible with G.657 series fibers for outdoor-to-building routing and access paths.

Outdoor Protection

Outdoor sheath supports exposed access routes before the cable enters the building.

Project Customization

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

Model	Messenger / Strength	Typical Use	Selection Note
GJYXCH	Steel messenger	Outdoor self-supporting FTTH drop route	Use for short aerial subscriber drop routes requiring steel messenger support.
GJYXFCH	FRP messenger / dielectric design	Outdoor self-supporting dielectric drop route	Use where a non-metallic outdoor self-supporting drop design is preferred.
GJXH	Indoor steel wire flat drop	Protected indoor FTTH routes	Use after building entry for indoor subscriber-side routing.
GJXFH	Indoor FRP flat drop	Protected indoor all-dielectric FTTH routes	Use for indoor non-metallic subscriber-side routing.

Application Scenarios

FTTH Subscriber Drop

Outdoor drop route from distribution point to subscriber premises.

Pole-to-Building Route

Self-supporting outdoor access route between pole and building entry point.

Building Entry

Outdoor-to-building access section before indoor routing begins.

Last-Mile Access

Short outdoor FTTH access links in residential or small commercial networks.

Wall Box Connection

Connection from outdoor terminal box to wall-mounted access point.

Custom Drop Route

Used where the project drawing calls for self-supporting outdoor FTTH drop cable.

When to Select GJYXCH Instead of a Similar FTTH Drop Cable

GJYXCH is intended for a short outdoor self-supporting subscriber drop where the route and drawing call for a steel messenger. Define the pole-to-building path, support points, building-entry transition, and installation length before approving the cable. It should not be treated as a substitute for an indoor drop cable after the route becomes protected, or for an ADSS design where longer span and separate engineering inputs govern the cable selection.

Choose GJYXCH when

The FTTH access section is a short aerial route and the specified self-supporting design uses a steel messenger.

Review another model when

A non-metallic messenger or dielectric requirement points to GJYXFCH; protected indoor routing after entry points to GJXH or GJXFH; longer-span engineering requires an ADSS review.

Approve before production

Confirm support-point spacing, route exposure, messenger requirement, fiber type, sheath, installation length, building-entry detail, and final termination method.

FAQ About GJYXCH Outdoor Self-Supporting FTTH Drop Cable

Q: What is GJYXCH used for?

GJYXCH is used for outdoor self-supporting FTTH drop routes, pole-to-building access, wall-mounted subscriber routes, and last-mile access links.

Q: What is the messenger wire used for?

The steel messenger provides support for self-supporting outdoor drop installation. Final messenger size and route suitability should be confirmed from span, clamps, and project requirements.

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 selected for FTTH drop cable routing.

Q: What is the difference between GJYXCH and GJYXFCH?

Both are outdoor self-supporting FTTH drop cable options. GJYXCH is commonly positioned with steel strength members and steel messenger, while GJYXFCH should be checked according to its final drawing and strength member design.

Q: Can GJYXCH be used for aerial routes?

GJYXCH is an FTTH drop cable, not a long-span trunk aerial cable. For longer aerial routes, review ADSS or figure-8 outdoor cable options according to span and route conditions.

Q: What should I send for quotation?

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