Loose tube cables the older of the two cable types are specifically designed for harsh outdoor environments.
Loose tube fibre cable.
They protect the fiber core cladding and coating by enclosing everything within semi rigid protective sleeves or tubes.
Loose tube and tight buffered.
Loose tube fibre cable.
Fiber loose tube cable belden s loose tube cables are ideal for both outdoor indoor outdoor applications including use in conduit direct burial lashed aerial trunking.
Loose tube fiber and tight buffered fiber.
The most proven fiber optic cable technology for long term reliability outdoors is the loose tube gel filled design.
This type of cable protects the fiber from stresses caused by the environment namely moisture and temperature.
Loose tube cables are designed for harsh environment conditions in the outdoors.
Each however is designed for very different environments.
From the picture below we can see that loose tube fiber holds more than one optical fiber each individually.
But there are two basic styles of fiber optic cable construction.
Both contain a type of strengthening member such as aramid yarn stainless steel wire strands or gel filled sleeves.
Loose tube is a commonly used fibre optic cable that is well suited for aerial lashed and direct bury installations.
This gel s main purpose is to protect the fibers from moisture which makes them the ideal choice if you happen to live in a harsh environment with high humidity where h2o and water condensation can be a major problem.
Fiber optic cables are constructed in two ways.
Fiber optic cable is available in many physical variations such as single and multiple conductor constructions aerial and direct burial styles plenum and riser cables etc.
Loose tube cables con also be found filled with a water resistant gel that surrounds every fiber it contains.
