Ultra Low Loss and Large Effective Area Single-mode Optical Fiber(G.654.E)

ZTT low loss and large effective area of single mode optical fiber is designed for long distance transmission system, and manufactured with MCVD technique. On the basis of the precise control of the refractive index, the fiber has low attenuation at C and L wave band; meanwhile, increase the effective area to suppress the nonlinear effect, which allows larger incident power, increases the nonlinear tolerance of the transmission system to meet the requirements of long distance and high capacity transmission and provide more system redundancy.

Small Size Single-mode Fiber （200um）

ZTT small size single mode fiber is to reduce the uncolored fiber from 250um to 200um through the precise control of the coating, which reduce the cable diameter efficiently and realize the larger fiber cables installation in the same duct resource to decrease the waste of duct space.

Fibre résistante à haute température

The maximum temperature of ordinary optical fibers is generally not allowed to exceed +85℃.If the temperature exceeds normal usage for a long time，the fiber coating will deteriorate，which has a bad influence on Fiber strength and service life.We can provide 150℃ and 300℃ resistant fiber，which could be used for high temperature communication and sensing application. The High temperature resistance is promoted by using special coating material and special design of coating die and curing process. The temperature resistant polyester or polyimide fiber can meet the performance requirements of 150℃ and 300℃.

Extended Wavelength of Non-dispersion Shifted Single-mode Fiber （G.652.D）

ZTT extended wavelength of non-dispersion shifted single mode optical fiber adopts advance perform and drawing technique which reduces the water peak value at 1383nm. The fiber working wavelength extends to E wave band(1360nm-1460nm) to realize the full-wave transmission of O, E, S, C, L（1260nm-1625nm）. Meanwhile, the innovated PMD rubbing equipment realizes the stable and good PMD coefficient when the high-speed production and it can meet the long distance and high-speed transmission.

Bending-loss Insensitive Single-mode Optical Fiber（G657A, G657B）

ZTT bending loss insensitive single mode optical fiber for access network has the properties of extended wavelength non-dispersion shifted single mode fibers and has bending resistance property with min. bending radius 7.5mm and 1 turn and bending loss＜0.5dB.ZTT bending loss insensitive single mode optical fiber adopts the UV curing technology; the coating material can be chosen; the fiber has single and double coating with easy stripping and small coating to meet different conditions.

Fibre optique multimode insensible aux pertes de flexion (OM2+, OM3, OM4, OM5)

La fibre optique multimode ZTT adopte la technologie MCVD avec un contrôle précis de l'indice de réfraction et fournit des fibres optiques multimodes sur mesure. Le type conventionnel est OM2+, OM3, OM4 et les clients peuvent choisir le type en fonction des exigences d'utilisation. La fibre optique multimode ZTT prend en charge le système de transmission 10Gb/s ; la distance de transmission est comprise entre 300 et 500 m à 850 nm. La fibre est conçue pour un laser à cavité verticale émettant à la surface à 850 nm à faible coût comme source lumineuse pour l'Ethernet Gigabit avec de bonnes propriétés, ce qui fournit des solutions pour un coût réduit et une bande passante élevée.
