WHAT TO CONFIRM
A few details make the choice clearer.
Select your route to see the questions that matter for this cable.
- Installation method and mechanical loads
- Fiber type, count and network requirements
- Jacket, protection and acceptance criteria
Every layer has a purpose.
Review the cable components, then confirm the drawing for the configuration you intend to order.
The approved cable drawing defines the final dimensions and materials.
Paired cable units
Confirm the duplex layout and separation requirements in the cable drawing.
Specifications, with context.
Use these references to frame your requirement. The quotation and approved cable datasheet define the product supplied.
GJFJV Duplex configuration guide
Start with the construction and installation requirements below.
- Cable construction
- Paired cable units · Tight-buffered fibers · Aramid reinforcementThe approved drawing defines materials, dimensions and tolerances.
- Optical configuration
- Specify the fiber category and countSelect against the network design, wavelengths and acceptance limits.
- Mechanical configuration
- Match the installation conditionsTensile, crush and bending limits depend on the complete cable construction.
Optical selection reference
Select the fiber and finished cable separately
G.652 describes single-mode fiber and cable; G.657 addresses bending-loss-insensitive single-mode fiber. Ask for the precise category and the finished-cable test limits needed by your network. For multimode requirements, state the OM category and link design.
G.652 attenuation limits are not a blanket specification for short indoor cables, jumpers or drop cables. Fiber bending performance also does not determine the minimum bend radius of a finished cable.
Sources & scope
Public technical references checked September 2026. Manufacturer examples illustrate a construction; they do not identify HONGKAI’s source factory or establish the specification of your order.
Compare the construction.
Then narrow your shortlist.
Keep the route and protection requirements in view when you compare cable families.
Simplex tight-buffered indoor cable
GJFJV SX
A simplex indoor connection built around a tight-buffered fiber, aramid yarn and a PVC or LSZH jacket. Match the fiber, cable diameter and jacket to the termination plan.
Mini-bundle indoor fiber optic cable
GJFV
A compact indoor mini-bundle construction with colored fibers and aramid yarn. Specify the fiber count, access method and final jacket requirements for your application.
Follow the equipment route for this cable.
GJFJV · indoor duplex — from fiber preparation to agreed acceptance and delivery. See HONGKAI equipment and process references matched to the listed construction.
The functions below explain how this construction is made. They are not a fixed machine count or a final equipment specification.
- 01
Fiber coloring & preparation
Start with the approved optical fiber. Apply and cure the specified identification colors, then rewind; if colored fiber is purchased, verify the incoming identification and package instead.
- 02
Tight-buffer formation
Form the specified buffer around each approved fiber, then cool, monitor dimensions and take up. Buffer material, dimensions, identification and reel interface follow the cable drawing.
- 03
Paired reinforced-unit preparation
Prepare the two protected optical units and their specified aramid reinforcement. Confirm identification, tension and the approved duplex layout.
- 04
Duplex jacket / profile formation
Form the approved paired-jacket or duplex-profile arrangement, then cool, measure, mark and take up. Tooling, web or separation details follow the drawing, not the shared indoor footage.
- 05
Inspection & delivery preparation
Complete the agreed optical and mechanical checks, inspection records, lengths, marking and packing. HONGKAI handles the agreed acceptance inspection and delivery; process videos are not batch test records.
The duplex layout is a configuration input. The related indoor equipment clip is not a recording of every duplex variant. Final materials, equipment interfaces and acceptance follow the approved drawing and order.
Optical fiber coloring and rewinding
HONGKAI coloring and rewinding footage: identification ink is applied and cured before the fiber is rewound. Already-colored input can enter the next approved production stage. Equipment and process reference only. Not proof of the manufacturing source, full equipment configuration or acceptance of your cable batch.

Only matching process functions have video controls. Other stages retain their explanation where suitable footage has not been established. These clips are not one continuous factory tour or a batch inspection record.
Independent factories manufacture the finished cable; HONGKAI handles customer-facing supply, payment, agreed acceptance inspection and delivery. Some equipment customers also manufacture the cables we supply. The actual source, specification and acceptance requirements are confirmed for each order.
Cable Supply with Clear Responsibility
HONGKAI supports cable machinery and production projects, and supplies finished fiber optic cables. Our finished cables are produced by independent factories in China that use HONGKAI equipment.
