Hengtong released a new product of "fully compatible single-mode optical fiber with high bending resistance", and the product presented 5 highlights

On August 17, 2013, the State Council of the People's Republic of China released the implementation plan of the "Broadband China" strategy, deploying the goals and paths of broadband development in the next eight years, which means that the "broadband strategy" has been upgraded from a sectoral action to a national strategy, and broadband has become a national strategic public infrastructure
for the first time.
Access network is a crucial part of broadband China's strategy, which is directly related to the Internet speed and broadband quality
of end users.
The backbone network is like a large artery on a person, and the access network is like a capillary on a person, and the demand for optical fiber in the access network is very large
.
The complex and narrow space environment in the access network requires the optical fiber to have strong bending resistance, good bending performance and high reliability, and has good compatibility
with the existing network optical fiber.
Therefore, Hengtong Optical Fiber adopts CCVD equipment and process technology with independent intellectual property rights to independently develop "fully compatible and high bending resistance bending insensitive single-mode optical fiber"
.

Dr.
Chen Wei, Chief Engineer of Hengtong Optical Fiber, introduced: Hengtong's new product development team ensures that the new G.
657.
B3 optical fiber products have excellent characteristics
of full compatibility and high reliability from the four dimensions of "innovative design, process technology, type test and practical test".

Hengtong released the new G.
657.
B3 optical fiber product of "fully compatible single-mode optical fiber with high bending performance", and the product presented 5 highlights:

Highlight 1: Hengtong G.
657.
B3 optical fiber new product has outstanding bending resistance

The new G.
657.
B3 optical fiber product independently developed by Hengtong has a macrobending additional loss of less than 0.
12dB for 1550nm wavelength and less than 0.
37dB for 1625nm wavelength under the condition of 5mm bending radius, which is suitable for applications in narrow spaces such as access networks, data centers, optical fibers to buildings and
interiors.

Highlight 2: Hengtong G.
657.
B3 optical fiber new product has good compatibility characteristics

Hengtong's self-developed G.
657.
B3 optical fiber new products are fully compatible with G.
657.
B2 and G.
657.
A2, as well as G.
652.
D.

The typical welding loss value of G.
652.
D single-mode fiber is 0.
081dB, which has good compatibility and is a good choice
for bending insensitive single-mode fiber for access network.

Highlight 3: Hengtong G.
657.
B3 optical fiber new product has precise and controllable geometric dimension characteristics

Hengtong adopts self-developed high-speed drawing tower equipment, and embedded in the "fuzzy theory" supported by the high-speed back control system, can realize the high-speed automatic back control of optical fiber, so as to achieve accurate control of optical fiber cladding diameter, Hengtong G.
657.
B3 optical fiber new product cladding diameter control in the range of 124.
70±0.
50μm, convenient for optical fiber into accurate ceramic ferrule, to achieve the perfect combination of optical fiber and ceramic ferrule, the optical fiber is suitable for the application of
leather cable products.

Highlight 4: Hengtong G.
657.
B3 optical fiber new product has full-band communication characteristics

Hengtong adopts CCVD equipment and process technology with independent intellectual property rights, conquers the core technology of optical fiber "heart", eliminates the hydroxyl absorption peak of optical fiber "core", and the typical absorption value of 1383nm wavelength is 0.
285dB/km
.
The new G.
657.
B3 optical fiber product launched by Hengtong is superior to the "2012 ITU-TG.
657" international standard, with the excellent characteristics of 1260nm~1625nm full-band communication, and is suitable for high-speed and large-capacity access optical fiber communication network
.

Highlight 5: Hengtong G.
657.
B3 optical fiber new product has good application scenario reliability

Hengtong's G.
657.
B3 optical fiber new products have undergone rigorous and scientific waveguide structure design, process development, product performance optimization, a full set of type tests and scenario application verification, and the technical team of Hengtong has carried out more than 10 tests and inspections such as "small radius bending, repeated bending, temperature cycling, high temperature and high humidity aging, high temperature aging, water immersion aging, peeling, dynamic fatigue, dynamic tensile, macrobending and microbending test, hydrogen loss experiment, loose PMD test" and other newly developed products.
The results show that all the new G.
657.
B3 optical fiber products have successfully passed the test and have good reliability
in application scenarios.
