The jelly-filled loose tube single-mode(SM) optical cable is structured with the silica SM fibers, and the cable is filled with jelly.Loose Tube Jelly-filled Single mode Optical Cable (BJF-SM Optical Cable)
Application:
1.The BJF-SM optical cables are suitable for long-haul and urban junction communication.
2.The transmission wavelengths are 1310nm and 1550nm for G.652 optical cable, 1530nm to 1625nm for G.655 NZD optical cable and broadband (1260nm to 1625nm) for G.652D.
Structure:
1.Standard loose tube
Basically, 6-fiber loose tube is applied in optical cable with optical fiber under 48C, 12-fiber loose tube is applied in optical cable with optical fiber above 48C.
