Indoor optical fiber cables are typically engineered to meet stringent fire safety and mechanical flexibility requirements, making them ideal for LAN, data center, and building backbone applications.
Indoor fiber optic cables are designed for safe, reliable performance within buildings, where flexibility, flame resistance, and ease of handling are critical.
The outer jacket is typically made from Low Smoke Zero Halogen (LSZH) material, which minimizes toxic emissions and smoke generation in case of fire. In some cases, PVC is used for economic indoor applications, while TPU can be selected for areas requiring higher flexibility and durability.
Inside the cable, tight-buffered fibers provide protection against mechanical stress and simplify termination processes. Strength members such as aramid yarn (Kevlar) enhance tensile strength, preventing fiber damage during installation.
Indoor cables are often designed to comply with fire safety standards such as OFNR (Optical Fiber Nonconductive Riser) or OFNP (Optical Fiber Nonconductive Plenum), making them suitable for vertical riser shafts, ducts, and plenums.
These construction features ensure that indoor fiber optic cables deliver stable signal transmission, flexibility, and safety in environments like offices, data centers, and commercial buildings.




Suitable for indoor environments such as offices, data centers, and buildings, indoor fiber optic cables offer excellent flexibility, easy installation, and flame-retardant performance. They are designed to meet strict fire safety standards while ensuring stable and high-speed data transmission within structured cabling systems.

Indoor fiber optic cable is specifically designed for use inside buildings, offering enhanced flame resistance, flexibility, and ease of installation compared to outdoor cables. The typical jacket materials for indoor cables include LSZH (Low Smoke Zero Halogen) and TPU (Thermoplastic Polyurethane) to ensure safety, environmental protection, and compliance with building codes.
Indoor cables are widely used for:
● FTTH / FTTB wiring
● Enterprise LAN networks
● Data centers and server rooms
● Building backbone cabling
● Telecom central officess.
The price of indoor fiber optic cable varies depending on several key factors:
Cable Type | Fiber Count | Unit Price (USD / Meter) |
Simplex Indoor Cable | 1 Core | $0.05 – $0.12 / Meter |
Duplex Indoor Cable | 2 Cores | $0.10 – $0.20 / Meter |
Distribution Cable | 4-24 Cores | $0.20 – $0.60 / Meter |
Breakout Cable | 4-24 Cores | $0.35 – $0.90 / Meter |
Note: Prices fluctuate based on fiber type (G657A2, G652D, OM3, etc.), jacket material (LSZH / TPU), production quantity, and shipping terms (FOB, EXW, CIF).
When sourcing indoor fiber optic cables, price should not be your only consideration. Here’s what typically affects the cost:
1. Cable Structure
● Simplex & Duplex: Ideal for short runs, lower cost.
● Distribution Cables: Multi-core options for higher density wiring.
● Breakout Cables: Suitable for easy termination, slightly more expensive.
2. Fiber Type
● Single-mode (G652D / G657A1 / G657A2)
● Multi-mode (OM1 / OM2 / OM3 / OM4 / OM5)
Multi-mode fibers, especially OM4 / OM5, generally increase cable cost.
3. Jacket Material
● LSZH: Fire-safe, eco-friendly, required in most indoor environments.
● TPU: Higher flexibility, stronger mechanical properties, slightly higher price.
4. Certification Standards
Cables compliant with ISO 9001 / CE / RoHS / UL / IEC / TIA may cost marginally more but guarantee long-term safety and performance.
5. Order Quantity
Larger volumes benefit from significant price reductions due to production economies of scale.
6. Lead Time & Delivery Terms
Urgent orders, customized colors, or OEM requests may slightly impact price.
Yes. Indoor cables can be manufactured with either single-mode or multimode fibers depending on the transmission distance and bandwidth requirements.
Indoor fiber optic cables usually comply with standards like OFNR (Riser Rated) and OFNP (Plenum Rated), depending on the installation environment.
Yes. Tight-buffered indoor cables are ideal for short-distance, high-density cabling such as patch cords and interconnects in data centers.
