GJFJV Indoor Fiber Optic Cable Selection Guide
Fire‑retardancy and building code compliance:
For indoor cabling installations, GJFJH (LSZH) is the mandated choice for fire‑sensitive public spaces, high‑rise building risers, tunnels, data centers, hospitals, schools, and any occupied space where building codes require low smoke and halogen‑free properties. LSZH sheathing emits minimal smoke and no halogen gases when burned, ensuring personnel safety and equipment protection in confined spaces.
GJFJV (PVC) is suitable for general indoor environments where fire codes permit PVC, such as equipment rooms (MDF/IDF) with adequate fire suppression, industrial facilities, and low‑occupancy spaces. PVC is flame‑retardant (UL OFNR/OFNP rated) but produces dense smoke and toxic halogen gases during combustion. Lower material cost makes GJFJV attractive for non‑fire‑rated areas.
Fiber core count and application type:
Both GJFJV and GJFJH support a wide core count range (2–144 cores), making them suitable for building backbone distribution. Their tight‑buffered construction allows direct termination to connectors without messy gel cleanup – a significant labour‑saving advantage over loose tube indoor cables.
GJFJBV is limited to 2‑core applications only . It is purpose‑built for patch cords, pigtails, desktop fiber connections (FTTD), and short jumper runs between instruments and communication equipment . Not suitable for backbone or multi‑core distribution.
| Requirement | Recommended Cable |
|---|---|
| Building backbone / riser, fire‑sensitive area (LSZH required) | GJFJH (LSZH jacket) |
| Building backbone / riser, general area without LSZH mandate | GJFJV (PVC jacket) |
| Patch cord, pigtail, equipment jumper, 2‑core desktop connection | GJFJBV (duplex flat) |
Cost‑performance summary:
GJFJV offers the lowest cost for multi‑core (2–144 core) indoor distribution where PVC is permitted. Its UL OFNR/OFNP rating satisfies basic flame‑retardancy requirements for riser/plenum spaces in many jurisdictions .
GJFJH carries a cost premium over GJFJV due to LSZH material, but is mandatory for fire‑rated spaces. The premium is justified by compliance with strict building codes and reduced life‑safety risk in occupied areas .
GJFJBV is the most economical 2‑core indoor cable for patch cords and equipment jumpers. Its low weight (13.8 kg/km) and compact dimensions make it ideal for high‑density patching fields, though its larger bend radius and lower tensile strength limit its use to short, low‑stress connections .
Installation ease and routing constraints:
For building riser and horizontal cabling requiring a balance of cost, core count, and ease of termination, GJFJV offers the most economical solution where fire codes permit PVC. For the same applications requiring fire‑rated LSZH, GJFJH is the correct choice despite the higher material cost [3†L15-L17].
For patch cord assemblies and equipment‑to‑instrument jumpers requiring 2‑core simplex or duplex connections, GJFJBV is the best choice. Its flat structure allows compact fibre arrangement, but its larger bend radius (60/30mm) and lower tensile strength (100–200N) make it unsuitable for backbone pulling [12†L18].
For installations with tight bend radius requirements, round distribution cables (GJFJV/GJFJH) offer superior flexibility (20D dynamic/10D static) compared to flat duplex cables [6†L25].
