Description:
Loose tube is made of colored optical fiber without filling waterproof compound. Loose tubes are stranded around the strength member which are in the central of cable into cable core, a layer of water-blocking tap is longitudinal wrapped around the cable core, after corrugated steel is longitudinal wrapped, an outer jacket is extruded.
Jacket:
Materials: PE, LSZH, ZRPE or other material.
Color: Black or other agreed color
Features
Application: Directly bury or Duct
Characteristic:
Good mechanical and environmental performance. High strength loose tube is hydrolysis resistant. Crush resistance and moisture barrier. Easy for construction, convenient for cable splicing
Temperature: -40ºC - 70ºC
Fiber count: 1-144F
Cable Dimension: 11-19.2mm
Package and shipping mark
Printing at out jacket of optical cable
White color printing words at each meter distance, standard printing content as following, also can match the customer require for the printing content
1). Meter mark
2). Style of optical cable and fiber account
3). Manufacturer name
4). Manufacturer date
5). Package of optical cable
- Standard length is 1KM, other length can negotiate
- Can be packed in wooden drum or plywood drum
Wooden drum
Label will be sticked at wooden drum, content as follow
1. Style of optical cable and fiber account
2. Length
3. Gross weight KGS
4. Total drums amount
5. Manufacturer date
6. The following information also will be exposed at the wooden drum
- Rolling direction
- Optical cable rolling tightly with the wooden drum, in order to prevent it will be broken during transportation process
