GJXFH vs GJXH vs GJYXCH vs GJYXFCH
These four FTTH drop cable models serve different indoor and outdoor subscriber routes. The main selection factors are installation environment, metallic or non-metallic strength members, messenger design, sheath requirement and route length.
Updated June 22, 2026 · MapleArashi FTTH Selection Guide
Quick Selection
- GJXFH: protected indoor route requiring FRP non-metallic strength members.
- GJXH: protected indoor route using steel wire strength members.
- GJYXCH: short outdoor self-supporting drop route using steel messenger wire.
- GJYXFCH: short outdoor all-dielectric self-supporting route using FRP components.
Four-Model Comparison Table
| Model | Environment | Strength / Messenger | Typical Route |
|---|---|---|---|
| GJXFH | Indoor | FRP strength members | Protected indoor subscriber routing |
| GJXH | Indoor | Steel wire strength members | Protected indoor subscriber routing |
| GJYXCH | Outdoor self-supporting | Steel strength members and steel messenger | Short pole-to-building aerial drop |
| GJYXFCH | Outdoor self-supporting | FRP strength members and non-metallic messenger | Short all-dielectric aerial drop |
GJXFH: Indoor Non-Metallic Drop Cable
GJXFH is normally used for protected indoor FTTH subscriber routes. It commonly uses FRP strength members, making it suitable where metallic reinforcement is not preferred.
Review the GJXFH product page for the available fiber count, fiber type, sheath and packing options.
GJXH: Indoor Steel-Reinforced Drop Cable
GJXH is also used for indoor subscriber-side FTTH routing, but it commonly uses steel wire strength members. It should be installed in protected indoor paths rather than exposed outdoor aerial routes.
Review the GJXH product page for the confirmed construction.
GJYXCH: Outdoor Steel Messenger Drop Cable
GJYXCH has a figure-8 self-supporting profile with a steel messenger wire. It is used for short outdoor subscriber drop routes such as pole-to-building or terminal-to-premises connections.
It is an FTTH drop cable rather than a long-span aerial backbone cable. Review the GJYXCH product page for the final messenger, sheath and route requirements.
GJYXFCH: Outdoor All-Dielectric Drop Cable
GJYXFCH is an outdoor self-supporting FTTH drop cable using FRP or other non-metallic reinforcing components. It is selected where the outdoor subscriber route should avoid steel strength members and steel messenger wire.
Review the GJYXFCH product page for the confirmed dielectric construction.
Indoor vs Outdoor Drop Cable
GJXFH and GJXH are intended primarily for protected indoor routing. GJYXCH and GJYXFCH are intended for exposed outdoor self-supporting subscriber drops.
Indoor cables should not automatically be used outdoors. Outdoor routes require the correct sheath, messenger design, UV resistance, temperature range and mechanical support.
Steel vs FRP Strength Members
- Steel wire: metallic reinforcement used in GJXH and commonly in GJYXCH.
- FRP: non-metallic reinforcement used in GJXFH and commonly in GJYXFCH.
- Steel messenger: supports the outdoor self-supporting GJYXCH route.
- Non-metallic messenger: supports the dielectric GJYXFCH route.
The final strength-member dimensions and mechanical properties must be confirmed from the proposed product drawing and data sheet.
FTTH Drop Cable Selection Workflow
- Confirm whether the route is indoor or outdoor.
- Confirm whether the cable must be self-supporting.
- Confirm whether metallic components are permitted.
- Confirm fiber count and G.657 fiber requirement.
- Confirm sheath material and fire-performance requirement.
- Confirm the outdoor span or subscriber drop distance.
- Confirm connector, packing and cable-marking requirements.

Frequently Asked Questions
What is the main difference between GJXFH and GJXH?
Both are normally used for protected indoor FTTH drop routes. GJXFH commonly uses FRP non-metallic strength members, while GJXH commonly uses steel wire strength members. The final construction must be confirmed from the product drawing.
What is the difference between GJYXCH and GJYXFCH?
Both are outdoor self-supporting FTTH drop cables. GJYXCH commonly uses steel strength members and a steel messenger wire. GJYXFCH commonly uses FRP strength members and a non-metallic messenger design for all-dielectric outdoor routes.
Which FTTH drop cable should be used indoors?
GJXFH or GJXH is normally selected for protected indoor subscriber routes. The choice depends on whether the project requires a non-metallic FRP design or permits steel strength members.
Which FTTH drop cable is used for pole-to-building installation?
GJYXCH or GJYXFCH is normally reviewed for short outdoor self-supporting pole-to-building drop routes. These are subscriber drop cables, not long-span aerial trunk cables.
Can GJYXCH be used as a long-span aerial cable?
GJYXCH is intended for short FTTH subscriber drop routes. For longer aerial spans, review ADSS or another engineered self-supporting outdoor cable based on span, wind, ice and route conditions.
What information is required for an FTTH drop cable quotation?
Provide the required model, fiber count, fiber type, indoor or outdoor route, messenger requirement, sheath material, route length, quantity, packing length, connector requirement and destination.
