Bending-loss Insensitive Multi-mode Optical Fiber（OM2+, OM3,OM4,OM5）

ZTT multi-mode optical fiber adopts MCVD technology with precise control of refractive index and provides customer-made multi-mode optical fiber. The conventional type is OM2+, OM3, OM4 and the customers can choose the type according to the use requirement. ZTT multi-mode optical fiber supports 10Gb/s transmission system; the transmission distance is in the range of 300—500m at 850nm. The fiber is designed for low-cost 850nm vertical cavity surface emitting laser as the light source of Gigabit Ethernet with good properties, which provides the solutions for the low-cost and high bandwidth.

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.

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.

High Temperature Resistant Fiber

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℃.

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.

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.
