FTTH Drop Cable GJYXCH-4C

Overview:

GJYXCH is compact mini figure-8 aerial self-supporting FTTH drop optical cable sized 5.2mm × 2.0mm, designed for indoor & outdoor dual-purpose last-mile fiber access. It features an integral figure-8 profile: upper part is high-strength steel messenger wire for overhead load bearing, lower fiber unit equipped with twin solid steel strength members alongside optical fibers. Available in 1, 2, 4 and 6 single-mode fiber configurations (G.652D / G.657A1 / G.657A2). Standard LSZH outer sheath supports cross outdoor aerial suspension and subsequent indoor penetrating wiring, widely used for pole-to-house FTTH cabling.

GJYXCH Cable Structure:

Steel Messenger Wire: Galvanized steel wire embedded in upper figure-8 lobe, undertakes overall cable tension and dead weight to realize self-support overhead installation.
Fiber Unit:

Optical fiber: 1/2/4/6 cores single-mode fiber, color-coded per IEC/TIA standard; G.657 series fiber for superior anti-bending performance.
Double parallel solid steel wires strength on two sides of fiber core, reinforcing anti-crush and tensile property of fiber unit.

LSZH Outer Sheath: Overall cladding for whole figure-8 structure with prefabricated tear notch; optional UV-resistant modified LSZH for long-term open-air exposure.

GJYXCH-4F

Key Features of GJYXCH FTTH Drop Cable:

Self-support FIG8 Integrated Design: No extra suspension steel wire needed for overhead laying, cutting accessory and construction costs; dimension fixed at 5.2×2.0mm for narrow-space routing.
Full-Steel Reinforcement: Inner dual steel strength members + top steel messenger deliver higher tensile capacity vs FRP-type GJYXFCH, enabling longer aerial span.
Tool-Free Quick Stripping: Built-in tear slit allows manual sheath splitting to separate messenger and fiber unit without professional stripping tools, accelerating field termination.
Indoor & Outdoor Dual-Use: LSZH low-smoke zero-halogen flame-retardant sheath meets indoor fire safety criteria; UV option available for all-weather outdoor anti-aging and sun-proof.
Excellent Anti-Bending & Anti-Compression: Compatible with bend-insensitive G.657 fiber, suitable for tight corner routing along wall, eaves and conduit.
Wide Operation Temperature: Standard: -40℃ ~ +70℃

Applications:

FTTH last-mile pole-to-residential building aerial drop cabling (urban communities, villages, countryside fiber renovation).
Short-span building-to-building overhead interconnection for campus, industrial park and commercial block access network.
Outdoor-to-indoor transition wiring: overhead from utility pole to building outer wall, then penetrate wall into room to connect ONT terminal.
Narrow-space installation along building eaves, exterior wall trunking and small-sized conduit for old district fiber upgrade.
6-core specification reserved for multi-dwelling unit (MDU) and spare backup fiber layout.

FAQs:

Q1: What's the structural difference between GJYXCH and GJYXFCH?

A: GJYXCH uses two parallel steel wires as strength members, while GJYXFCH adopts dual FRP rods.

Q2: What fiber types and core counts are available for this 5.2×2.0mm cable?

A: Available core options: 1,2,4,6 cores single-mode fiber; Matching fiber types: G.652D, G.657A1, G.657A2

Q3: Is the outer sheath LSZH? Can it be used both outdoors and indoors directly?

A: Standard sheath is LSZH low smoke zero halogen flame retardant. It can be overhead outdoors first then directly routed into buildings for indoor wiring.

Q4: Size is fixed at 5.2×2.0mm, any customized dimension?

A: The size 5.2*2.0mm is popular among clients, normal dimension is 5.0*2.0mm. Customized size also is available.

Q5: Can we strip the cable without special cutting tools on site?

A: Yes. Pre-made tear slot on the sheath. Installers can rip sheath by hand to separate top steel messenger and bottom fiber unit easily for fast connector termination.

Q6: What's the usage difference for different core numbers (1/2/4/6 core)?

1/2 core: Single household FTTH access;
4 core: Small multi-family building with spare backup fiber;
6 core: MDU, residential cluster and network expansion reserve.
