Optical fiber technology was originally developed for data center applications. From the current development perspective, it will soon become an ideal choice for building a backbone network.
With the development and application of wireless technology, the horizontal wiring bandwidth in commercial and industrial buildings has exceeded 1Gbps, and the ensuing requirement is that the integrated wiring backbone infrastructure supports speeds of at least 40Gbps and 100Gbps. This means that the high-density application promotion of the data center is very suitable for the current development and demand. The optical fiber OM5 broadband can not only support 802.11ac wi-fi systems, but also support high-density 5G wireless networks.
Basic knowledge of high-density OM5 fiber
ISO and TIA standardization organizations released the latest wiring standards ISO 11801 3rd and TIA-568.0-D in 2017, respectively.
OM5 Broadband Multimode Optical Cable: The attenuation is reduced from 3.5 dB / km of the previous OM3 and OM4 optical cables to 3.0 dB / km. In addition, the bandwidth requirement at the wavelength of 953 nm is increased. The geometry of OM5 (50μm core wire, 125μm cladding) is the same as OM3 and OM4, so it is backward compatible with these types of optical fibers.
OM5 fiber also supports future 400G Ethernet. For higher speed 400G Ethernet applications such as 400G Base-SR4.2 (4 pairs of fiber 2 wavelengths, each channel uses 50G PAM4) or 400G Base-SR4.4 ((4 For 4 wavelengths of fiber, each channel uses 25GNRZ), only 8-core OM5 fiber is required. OM5 fiber is a laser-optimized multimode fiber (MMF), which specifies bandwidth characteristics for wavelength division multiplexing (WDM). The purpose of this new fiber classification method is to provide support for a variety of "short" wavelengths between 850nm and 950nm, and wavelengths in this range are suitable for high-bandwidth applications after polymerization.
What is the difference between OM5 fiber jumper and OM3 / OM4 fiber jumper?
1. Outer sheath color: Generally speaking, the outer sheath color of OM3 and OM4 fiber jumpers is turquoise or purple, and the outer sheath color of OM5 fiber jumpers is aqua.
2. Wavelength: The working wavelength of OM5 fiber jumper is 850 / 1300nm, and can support at least 4 wavelengths. The normal operating wavelengths of OM3 and OM4 are 850nm and 1300nm. In the same wavelength window, the transmission distance of this multimode fiber jumper is also different.
3. Effective mode bandwidth (EMB): OM5 fiber patch cord has a higher breakthrough in effective mode bandwidth (EMB), it will increase the effective mode bandwidth (EMB) at 850nm wavelength to 6000MHZ.km, around 880nm wavelength It reaches 8000MHZ.km, which is far more than the traditional OM3 and OM4 multimode fiber jumpers.
What are the advantages of OM5 fiber jumper?
High degree of recognition: OM5 fiber jumper was originally released as TIA-492AAAE by the Communications Industry Association, and was unanimously approved in the ANSI / TIA-568.3-D revision opinions issued by the American National Standards Institute;
High scalability: OM5 fiber jumpers can combine short-wavelength division multiplexing (SWDM) and parallel transmission technology in the future, and only require 8-core broadband multimode fiber (WBMMF) to support 200 / 400G Ethernet application;
Reduce cost: OM5 fiber jumper draws on the wavelength division multiplexing (WDM) technology of single-mode fiber to extend the usable wavelength range during network transmission. It can support 4 wavelengths on a 1-core multimode fiber and convert the required fiber core The number is reduced to 1/4 before, which greatly reduces the wiring cost of the network;
Compatibility and strong interoperability: OM5 fiber jumpers can support traditional applications just like OM3 fiber jumpers and OM4 fiber jumpers, and it is fully compatible with OM3 and OM4 fiber jumpers and highly interoperable.
