Non-dispersion shifted single-mode fiber (G.652B)

Product introduction:
Extended wavelength band dispersion unshifted single-mode optical fiber (G652.D)
Bend insensitive single-mode optical fiber (G657.A2)
Product description:
Such product is applicable for 1260-1625nm full-band transmission system; it mitigates water-peak consumption near 1383nm because of OH- ion absorption, and extends working window to E band (1360-1480nm) which further increases bandwidth by about 100nm; attenuation and dispersion characteristics of 1260-1625nm band is optimized, macro banding resistance performance of band L (1565-1625nm) is promoted which fully satisfies requirements for conducting multi-communication channel high rates transmission on single optic fiber.
Product features
Efficient protective coat and good peeling property
Accurate geometric parameters guarantee low splicing loss and high splicing efficiency
Low polarization membrane dispersion enables high rate and remote transmission
Low attenuation and low dispersion satisfy working requirements of 1310nm and 1550nm window
Minimum bending radius of G657.A2 is 7.5mm, which indicates splendid bending resistance performance and perfect accommodation with G652 single-mode optical fiber
Product process
The product is manufactured with PCVD process; such optical fiber compromises characteristics of accurate refractive index distribution control, terrific geometric features and low attenuation thanks to advantages of PCVD process.
The adopted double UV adhesive acrylate coat is of good optical fiber protection capability. Application of such coat aims to facilitate tight buffered optic cables with higher requirements, such coat also gives outstanding performance in loose tube structures and enables rather efficient micro bend resistance performance; such coat may be easily peeled under any conditions without any residual on naked optic fiber; optic fibers may possess outstanding and stable fatigue resistance performance and significantly increased adaptability toward band conditions.
Execution standards:
Satisfy or better than requirements stated in ITU-TG.652.D&IECB3.1 optic fiber technical specification.
Satisfy or better than requirements stated in ITU-TG.657.A1/A2/B2 optic fiber technical specification.
Production application:
G652.D optic fiber is applicable for various optical cable structures, including fiber ribbon cable, loose tube stranded cable, slotted-core optical cable, central tube type cabl, tight buffered cable, etc; such fiber is compatible to other similar type optic fibers manufactured by other processes.
G657.A2 optic fiber satisfies requirements of optic cables in different structures, transmission in full 1260nm-1626nm band, FTTH high rate optical routing, optic cables with low bending radius requirements, small-size optic cables and optic fiber components, and application of band L.
