Q1: What is the difference between LSOH and LSZH?

A: There is no functional difference. Both terms—LSOH (Low Smoke Zero Halogen) and LSZH (Low Smoke Zero Halogen)—refer to the exact same jacket material. They are used interchangeably in European, Latin American, and global telecom specs. The material is engineered to produce minimal smoke and release zero toxic halogen gases during combustion (in compliance with IEC 60754-1/2).

Q2: Why choose a Central Loose Tube design for indoor fiber cables?

A: A Central Loose Tube design houses multiple fibers (typically 2 to 24 cores) inside a single protective tube. This offers two key advantages:

Compact & Lightweight: It occupies less space than multi-fiber tight-buffered cables, making it much easier to pull through tight conduits and vertical building shafts.

Mechanical Protection: The central tube insulates the inner fibers from external tensile loads, crushing forces, and severe bending strain.

Q3: What fire safety standards does an indoor LSOH cable meet?

A: LSOH outer jackets comply with international flame-retardant standards such as IEC 60332-1 (single vertical cable test) and IEC 60332-3 (bunched cables test). They are optimized for indoor distribution in data centers, commercial buildings, and public facilities where human safety and corrosion prevention for electronic equipment are critical.

Q4: How is fiber splicing handled for Central Loose Tube cables?

A: During termination at a patch panel or distribution box, the outer jacket and central tube are stripped, and the protective gel is wiped clean. Because the individual fibers inside are standard 250 µm coated fibers, technicians typically use a fan-out kit (furcation kit) to sleeve and protect the bare fibers before fusion splicing or connectorization.
