Changfei Super Bay Broadband OM5 Multimode Fiber Provides Solution for Data Center 100G Transmission

In recent years, network data traffic has grown rapidly, and data center requirements for bandwidth have become higher and higher. The construction of next-generation data centers requires transmission media with lower cost and wider bandwidth.

The Super Bay® broadband OM5 multimode fiber developed by Changfei supports communication transmission of at least 4 wavelengths in the 850-950nm wavelength range, thereby supporting the latest Short Wavelength Division Multiplexing (SWDM) technology. The principle of short-wavelength division multiplexing is shown in Figure 1. Compared with the existing parallel technology, the short-wavelength division multiplexing technology reduces the amount of multimode fiber to a quarter, that is, using two-core fiber (instead of eight). Core) can achieve 100 G bidirectional transmission. If a fiber is considered as a highway, short-wavelength division multiplexing is like widening a single-lane road into four lanes, and the capacity is increased by four times.

The Ultra-Bell® Broadband OM5 multimode fiber not only provides bandwidth performance comparable to 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 process used by Changfei Company enables ultra-fine refractive index profile control, combined with waveguide material optimization, to make the Super Bay® broadband OM5 multimode fiber excellent in longer wavelength windows. Bandwidth performance.
The Super Bay® Broadband OM5 multimode fiber uses a profiled design of the depressed cladding structure to achieve excellent bending resistance. The refractive index profile is the same as that of the traditional OM3 and OM4 multimode fibers, so it is perfectly compatible with traditional OM3 and OM4 multimode fibers.

In the 100G transmission test, the Super Bay® broadband OM5 multimode fiber achieved error-free transmission of more than 300m.

Changfei's Super Bay® broadband OM5 multimode fiber not only provides a low-cost, low-energy, high-performance, and perfectly compatible high-quality solution for data center 100G transmission, but also prepares for further upgrade to 200G and 400G in the future.
