Product Description

Low Loss bare color Single-Mode Optical Fiber G652D

Type
 Low loss single-mode optical fiber(LL G.652.D)
Standard
 The fiber comply with or exceed ITU-T G.652D & IEC B1.3. specification.
Features

• 1260~1625nm full band transmission;
• Restraining water loss of the ordinary single-mode fiber at the vicinity of 1383nm absorption peak which caused by hydroxyl ions;
• Expanding the working window to E wave band(1360~1460nm) and increasing the spectral bandwidth of about 100nm;
• Reducing significantly the attenuation of the 1260~1625nm full band;
• Fully meeting the single fiber to realize multi channel.high speed, long distance transmission requirements.

Application
Suitable for all optical cable constructions, including ribbon, loose tube stranded, slotted core, central tube, tight buffered designs.

The company produces and tests optical fiber independently, all qualified fibers meet the requirements of technical specifications.

Packaging and storage

• Ensure no foreign matter on the reel and fiber surface, wrap it with film and cover, and label fiber coding on the reel and cover respectively.
• The packaged optical fiber is stored at a constant temperature of 25ºC in a light-proof warehouse. The products are fixed in the carton when they are shipped out of the warehouse. The carton number and fiber coding information are attached to the carton, and the electronic test report is attached to each shipment.
