Hengtong pushes new bend-resistant single-mode fiber

On August 17, 2013, the State Council of China released the "Broadband China" strategy implementation plan and deployed broadband development goals and paths for the next eight years. This means that the "broadband strategy" has risen from a departmental operation to a national strategy, and that broadband has become a national strategic public for the first time. infrastructure.

The access network is a crucial part of the broadband China strategy and is directly related to the end user's Internet access rate and broadband quality. The backbone network is like an aorta in humans, and the access network is like a person's capillaries. The access network has a large demand for optical fibers. The complex and narrow space environment in the access network requires that the optical fiber has strong anti-bending performance, good bending performance and high reliability, and has good compatibility with the existing optical fiber. Therefore, Hengtong Optical Fiber has independently developed a curved insensitive single-mode optical fiber that is fully compatible with high bending performance, using its own proprietary CCVD equipment and process technology.

Dr. Chen Wei, Chief Engineer of Hengtong Optical Fiber Co., Ltd. introduced: Hengtong's new product development team guarantees G from the four dimensions of “innovative design, process technology, type testing, and practical inspection”. 657. The new B3 fiber products are fully compatible and highly reliable.

Hengtong released "Compatible with high bending performance single mode fiber" G. 657. B3 new fiber products, products show five highlights

Highlight 1: Hengtong G. 657. New B3 fiber products have outstanding resistance to bending

Hengtong's self-developed G. 657. Under the condition of a 5mm bending radius, the new B3 fiber product has a macrobending additional loss of less than 0.12dB at a wavelength of 1550nm, a macrobending additional loss of less than 0.37dB at a wavelength of 1625nm, and is suitable for access to narrow spaces such as access networks, data centers, optical fibers, and buildings. Application occasions.

Highlight two: Hengtong G. 657. B3 new fiber products have good compatibility

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

With G. 652. The splice loss of D single-mode optical fiber is 0.081dB, which is a good choice for bend-insensitive single-mode optical fibers in access networks.

Highlight three: Hengtong G. 657. New B3 Fiber Products with Accurate and Controllable Geometric Dimensional Features

Hengtong adopts self-developed high-speed wire drawing tower equipment and embeds a high-speed control system supported by “fuzzy theory” to achieve high-speed automatic control of the optical fiber, thereby realizing precise control of the diameter of the optical fiber cladding, Hengtong G. 657. The diameter of the new B3 fiber product is controlled within the range of 124.70±0.50 μm, which makes it easy for the optical fiber to enter the ceramic ferrule accurately, and realizes the perfect combination of the optical fiber and the ceramic ferrule. This fiber is suitable for the application of the leather cable product.

Highlight four: Hengtong G. 657. New B3 Fiber Products with Full-band Communication Features

Hengtong adopted proprietary CCVD equipment and process technology to overcome the "heart" core technology of optical fiber and eliminate the hydroxyl absorption peak of the optical fiber "core". The typical absorption value at the wavelength of 1383nm is 0.285dB/km. Hengtong launched the G. 657. The new B3 optical fiber products are superior to the "2012 ITU-T G.657" international standard and have the excellent characteristics of 1260 nm to 1625 nm full-band communications, and are suitable for high-speed and large-capacity optical fiber communication networks.

Highlight 5: Hengtong G. 657. New B3 Fiber Products Have Good Application Scene Reliability

Hengtong's G. 657. The new B3 fiber product undergoes rigorous and scientific waveguide structure design, process development, product performance optimization, a full range of type tests, and scene application verification. The Hengtong technical team performs “small radius bending, repeated bending, and temperature on newly developed products”. Circulation, high-temperature and high-humidity aging, high-temperature aging, immersion aging, peeling, dynamic fatigue, dynamic stretching, macrobend and microbend tests, hydrogen loss test, loose PMD test, etc. 657. All new B3 fiber products have successfully passed the test and have good reliability in application scenarios.

Hengtong adheres to the development concept of “innovation-driven development” and encourages original innovation. Hengtong attaches great importance to and respects the various needs and special needs of customers, insists that innovation comes from the market, innovation serves the market, and ultimately creates new value for customers, and achieves mutual development with customers and lasting win-win.
