In recent years, network data traffic has grown rapidly, data centers have become increasingly demanding on bandwidth, and the construction of next-generation data centers requires lower-cost, wider-bandwidth transmission media.

The ultra-wideband OM5 multimode fiber developed by Changfei Technologies supports transmission of at least 4 wavelengths in the wavelength range of 850-950nm, and can support the latest shortwave wavelength division multiplexing (SWDM) technology. The principle of shortwave wavelength division multiplexing is shown in Fig. 1. Compared with the existing parallel technology, the shortwave wavelength division multiplexing technology reduces the use of multimode fiber to a quarter, that is, using two core fibers instead of eight. The core) can realize 100 G bidirectional transmission. If an optical fiber is regarded as an expressway, short wave wavelength division multiplexing is like expanding a single-lane highway into four lanes and increasing its capacity by four times.

Super-Bright? Broadband OM5 multimode fiber offers not only bandwidth performance comparable to that of OM4 multimode fiber in the 850nm window, but also has high bandwidth in the 850-950nm wavelength range. The plasma chemical vapor deposition (PCVD) rod technology used by Changfei Company can achieve ultra-fine refractive index profile control. Combined with the optimization of waveguide materials, the super-wideband OM5 multimode fiber has excellent performance at longer wavelength windows. Bandwidth performance.

Ultra-Bell OM5 multimode fiber adopts the profile design of the depressed cladding structure to obtain excellent anti-bending performance. Its refractive index profile is the same as that of the traditional OM3 and OM4 multimode fibers, and therefore it is perfectly compatible with the traditional OM3 and OM4 multimode fibers.

In the 100G transmission test, Ultra-Brightband OM5 multimode fiber achieved error-free transmission over 300m.

Changfei SuperBridge? Broadband OM5 multimode fiber not only provides a low-cost, low-power, high-performance and perfectly compatible high-quality solution for data center 100G transmission, but also prepares for further upgrades to 200G and 400G in the future.


Shredder Blades For Tyre


Tire shredding is a technology for processing waste tires. The Shredder breaks the tires into smaller pieces or particles for subsequent recycling. This technology is of great significance in waste management and resource reuse.
1. Working principle
Shredding process: The tire shredder cuts and tears the tires through rotating blades or knife rollers, tearing the complete tires into small pieces or particles.
Staged shredding: Tires are usually large and strong and need to go through multiple stages of shredding. Primary shredding breaks the tires into larger pieces, which are then further refined through secondary shredding.
2. Application areas
Rubber recycling: Shredded tire fragments can be used to produce recycled rubber for the manufacture of new tires, rubber flooring, sports field covering materials, etc.
Fuel utilization: Shredded tire fragments can be used as alternative fuels and are widely used in high-energy consumption industries such as cement plants, pulp and paper mills, etc., effectively reducing dependence on traditional fuels.
Geotechnical materials: Tire fragments can be used in geotechnical construction materials, such as roadbed fillers, drainage layers, etc., to improve soil stability and drainage performance.
