Introduction of Indoor Optical Fiber Cable for Cabling in Buildings
Optical cables for vertical cabling wiring in buildings, which is a significant component of the drop segment in FTTxnetworks, refer to the drop cables going from ducts in buildings into rooms. Vertical wiring is mainly applied to high-story buildings, super high-story buildings, buildings with high-density subscribers And large information processing centers such as data centers.
Features
● Good flame-retardant performance ensuring communication under fire conditions ● Small size and lightweight, allowing large transmission capacity in limited space ● Good mechanical performance, including anti-bending and good tensile performances ● Anti-corrosion, water blocking, flame-retardant, and environment-friendly ● Allowing branching, easy connection

Analysis and Insights
Common Traits:
All cables feature tight-buffered G.652D/G.657A1 fibers for flexibility and LSZH (or PVC for GJJV) sheaths for fire protection, appropriate for indoor use. They comply with standards like IEC 794 and YD/T 1258.2-2003.
Structural Variations:
Single/Duplex: GJJV (its single core), GJFJH (round duplex), and GJFJBV (flat duplex) are employed for simple and low fiber counts, such as patching or some short links.
Multi-Core: GJPFJV (bundle), GJBFJV-I, GJBFJV-II, and GJBFJVH (branch) have the capacity to connect multiple fibers for distribution or upward wiring, with GJBFJVH large enough for networks.
Breakout: GJPFH, GJPFXJH, and GJPFWQH are ideal for breakout uses, having micro-tubes (GJPFH, GJPFWQH) for flexibility and density or tight buffers (GJPFXJH).
CSM (FRP): Either GJBFJV-I or GJBFJVH may be employed to support vertical or high fiber-count applications structurally.
FRP: GJPFXJH and GJPFWQH increase the strength of breakout cables without a central member.
Applications:
Patching/Pigtails: GJJV, GJFJH for limited distances or couplers.
Horizontal/Vertical Wiring: GJFJBV (flat duplex), GJPFJV, GJBFJV-I, GJBFJV-II, predominately for building distribution.
Large Networks:GJBFJVH as the choice for data centers or high-density networks.
Breakout:GJPFH, GJPFXJH, GJPFWQH for the transition to individual fibers in complex installations.
Key Differentiators:
The fiber-count number ranges from 1 (GJJV) to 144 (GJBFJVH), which allows scaling for every network scale.
Cables for breakout (GJPFH, GJPFWQH) utilize micro-tubes to save space, while GJPFXJH leads to direct connection from an individual fiber.
Design differences between flat (GJFJBV) and round (GJFJH) duplex cables are to be taken into consideration in order to provide the proper installation needs.
The cables presented are the solution to the indoor optical networking, balancing fibercount, flexibility and fire safety, which can be used to patch or to build huge data centers. Tell me whether you need another thing or comparison.
