Fiber Optic Cable Types Overview
Fiber optic cables vary significantly in construction depending on their intended environment. Key types include:
Loose Tube Cable: Fibers move freely inside buffer tubes. Water-blocking gel protects against moisture. Best for outdoor aerial and conduit installation. Terminates in splice closures.
Tight Buffer Cable: 900µm buffer coating directly over fiber. Flexible, small diameter. Ideal for indoor use and patch cable manufacturing.
Armored Cable: Metal or FRP armor layer for mechanical protection. Crush resistant, rodent-proof. For direct burial and harsh environments.
Plenum/Riser Cable: Low-smoke zero-halogen (LSZH) jacket. Fire safety rated for building vertical shafts and air handling spaces.
Rodent-Proof Cable: Steel tape or stainless steel braid armor. For areas with rodent or termite activity.
ADSS (All-Dielectric Self-Supporting): No metal components. Self-supporting between poles. Ideal for power utility communication networks.
Fiber Type Standards
G.652 (standard single-mode), G.657 (bend-insensitive for FTTH), OM1-OM5 (multimode for short-reach high-speed). Our SFP modules support all fiber types.
Conclusion
Choose cables based on installation environment: loose tube for outdoor, tight buffer for indoor, armored for direct burial, plenum for building risers. Visit Langzhi Technology for complete fiber optic solutions.
