Product Comparison:
| Feature / Dimension | GYFBY (Flat Outdoor Drop Cable) | GJFJH (Indoor LSZH Breakout Cable) | GJFJV (Indoor PVC Breakout Cable) |
|---|---|---|---|
| Typical Applications | FTTx last‑mile drop, outdoor aerial (self‑supporting), duct, direct burial. Connects distribution points to subscriber access points. | Indoor backbone cabling, building vertical risers, data centers, equipment rooms, high‑density cabling environments with fire safety requirements. | Indoor general‑purpose cabling, patch cords, pigtails, office LAN, communication equipment connections – environments without strict low‑smoke mandates. |
| Cable Structure | Flat elliptical shape, single loose tube, two FRP parallel strength members, PE sheath. All‑dielectric – no metallic components. | Tight‑buffered fibers (ф900μm/ф600μm) as subunits, aramid yarns as strength member, LSZH (Low‑Smoke Zero‑Halogen) outer jacket. Non‑metallic structure. | Same tight‑buffered fiber + aramid yarns construction as GJFJH, but with PVC (Polyvinyl Chloride) outer jacket instead of LSZH. |
| Pros in Engineering | Excellent tensile strength and crush resistance; compact flat design for easy handling; non‑metallic – no bonding/grounding required; UV‑resistant PE sheath. | Excellent flexibility and bending resistance; low smoke and halogen‑free – safe for fire‑sensitive areas; easy to strip and direct connector termination; non‑metallic – immune to EMI. | Lower material cost than LSZH; good flexibility and mechanical/environmental performance; easy stripping and termination; PVC provides good durability for general indoor use. |
| Cons in Engineering | Primarily outdoor‑rated – not optimized for indoor plenum use (PE jacket, no flame‑retardant rating). LSZH variant less common. | Higher cost than PVC due to LSZH material and stricter manufacturing; LSZH slightly less flexible than PVC in cold environments. | PVC releases dense smoke and toxic fumes when burned – unsuitable for fire‑sensitive spaces (e.g., high‑rise buildings, hospitals, subways). May fail building code requirements in plenum areas. |
| Cost (Relative) | Medium‑Low – economical for FTTH drop segments due to simple uni‑tube design and non‑metallic FRP reinforcement. Optimized for fiber counts up to 24 fibers. | Medium – LSZH material and tight manufacturing tolerances add cost; aramid yarns also increase price vs. polyester alternatives. | Low – most economical indoor breakout option; PVC is inexpensive, widely available, and easy to manufacture. |
| Maintenance Difficulty | Low – flat shape fits standard drop clamps; field splicing requires typical outdoor cable tools; no grounding required. Corrosion not a concern (non‑metallic). | Low – tight‑buffered fibers are easy to access and splice/terminate; LSZH jacket resists chemical degradation; non‑metallic – no rust. Ideal for high‑density environments where frequent patching occurs. | Low – same easy‑access tight‑buffered termination as GJFJH; PVC jacket remains flexible for long service life. However, poor fire performance may pose replacement risk if building codes change. |
| Flame Retardancy | PE jacket – flame retardant not specified for indoor plenum use. Typically lacks LSZH rating. Indoor deployment requires compliance verification. | LSZH jacket – certified for indoor flame‑retardant use. Low smoke, halogen‑free, meets fire safety standards for high‑rise buildings and public spaces. | PVC jacket – flame‑retardant but produces dense smoke and halogen gas. Not suitable for plenum/riser spaces per many building codes. |
GYFBY/GYFXY fiber optic cable Selection Guide
Choose GYFBY for outdoor FTTH drop applications – aerial, duct, or direct burial. Its flat, all‑dielectric design with UV‑resistant PE sheath offers excellent tensile strength and crush resistance with no grounding required. Ideal for connecting distribution points to subscriber premises. However, it lacks indoor flame‑retardant ratings, so verify local codes if used indoors.
Choose GJFJH for indoor backbone and riser cabling in fire‑sensitive environments – high‑rise buildings, data centers, hospitals, or public spaces. Its LSZH jacket emits low smoke and no halogens when burned, meeting strict safety standards. Though more expensive than PVC, it is the mandatory choice where fire codes require low‑smoke, halogen‑free materials.
Choose GJFJV for general indoor applications without strict low‑smoke requirements – office LANs, equipment rooms, and patch cord assemblies. It offers the same easy termination as GJFJH but at lower cost due to PVC sheathing. However, avoid it in plenum spaces or high‑occupancy buildings where smoke toxicity is a concern.
Quick summary:
Outdoor drop / burial → GYFBY
Indoor fire‑rated areas → GJFJH
General indoor, budget‑sensitive → GJFJV
GYFBY Installation Guide (Short)
1. Preparation: Inspect the cable for any sheath damage. Use proper stripping tools to remove the PE jacket without nicking the FRP strength members or the loose tube.
2. Aerial (self-supporting): Install the cable directly between poles using figure-8 clamps or drop hooks. Maintain sag of 1–2% of span length (typical span up to 100m). No separate messenger wire needed.
3. Duct installation: Pull the cable using a pulling grip attached to the FRP members, not the jacket. Use lubricant for long runs. Avoid exceeding the recommended pulling tension (typically ≤ 500N).
4. Direct burial: Lay the cable in a sand bed at least 30 cm deep. For rocky soil, use a protective conduit or additional sand layer. The PE sheath provides good moisture and rodent resistance.
5. Splicing & termination: The flat shape allows easy stripping. Use field-installable connectors or fusion splice to pigtails. Grounding is not required because GYFBY is all-dielectric (no metal).
6. Final check: Perform OTDR test to verify low attenuation and inspect for any kinks or excessive bends. Maintain minimum bend radius of 10× cable height during installation.
