GJYXCH Self-Supporting FTTH Drop Cable
The GJYXCH Self-Supporting Butterfly Drop Cable is purpose-built for the final drop section of FTTH (Fiber to the Home) networks—connecting the distribution cabinet or pole-mounted splitter to the subscriber premises. Featuring a figure-8 (“bow-tie”) self-supporting structure with a galvanized steel messenger wire and two parallel steel strength members flanking the central single-mode fiber, this cable delivers the tensile strength required for aerial span installation without the need for a separate messenger.

Application Scenarios of GJYXCH Drop Cable
GJYXCH is figure-8 structured self-supporting butterfly drop fiber cable with an independent steel messenger wire for aerial load-bearing, widely used for FTTH last-mile indoor & outdoor integrated wiring across telecom, smart building and IoT fields.
Aerial wiring from pole to residential building / individual household, drop cable for last-mile home broadband, IPTV and telephone access, widely used in new residential communities and old community optical fiber renovation.
Overhead layout along wall or utility pole for villa cluster, small residential park, one cable from outdoor pole directly into indoor wall hole without cable transition.
Rural pole-to-house aerial wiring, long-span overhead installation across countryside road and farmland, ideal for scattered rural households access.
Internet access for retail shops, small supermarkets, office rooms, monitoring network wiring for street-side small merchants.
Outdoor aerial wiring for community surveillance camera, roadside monitoring equipment connection, short-distance overhead fiber link.
Short-distance overhead fiber inside campus, scenic spot and industrial park for temporary network or fixed access.

GJYXCH fiber optic cable approx. 5.2 × 2.0 mm flat section + messenger; easy to coil, transport, and deploy in dense urban or rural settings.
Frequently Asked Questions
Standard: 1 core G.657A1/A2; optional 2 cores, 4 cores for dual-network backup. G.657 fiber features excellent bending resistance for corner wall routing.
Under typical conditions with proper lashing, spans up to 50–80m are common. For longer spans, consult our structural engineer or request a heavy-duty messenger specification.
- Black PE sheath: outdoor aerial overhead, anti-UV, rainproof, outdoor pole mounting;
- LSZH flame retardant sheath: indoor wiring, malls, high-rises, underground weak current wells, low smoke when burning.
No. Butterfly pre-groove design allows manual stripping of sheath without professional cutter, fast field fusion splicing or cold connection construction.
Yes, dual-purpose indoor-outdoor design: overhead from utility pole to building outer wall, then enter indoor along wall trunking/PVC pipe directly, no intermediate cable transition joint needed.
Fully dielectric fiber core, free from electromagnetic interference, suitable for laying near power lines, street power poles.
Built-in steel messenger wire bears aerial pulling force, no extra suspension steel wire needed, saves construction cost and shortens construction period for pole-to-home overhead.
