5G is coming, which fiber optic fiber will be hot sale

5G construction has brought huge demand for optical fiber, which has spawned new industry technology competition. As we all know, 5G has high-speed, low-latency and other performances, which can provide more reliable and stable network connection services. At the same time, due to the use of high-frequency signals, the coverage of 5G base stations is limited, so the demand for base station construction has increased significantly. It is estimated that by 2025, the total number of global 5G base station construction will reach 6.5 million, which meet new requirements and challenges for the performance and technological development of optical fiber and cable.

The following are five popular fiber optic cables suitable for 5G networks, which can help solve practical problems in 5G construction to a certain extent.

1. Bending-insensitive fiber optic jumpers easily implement indoor micro base station deployment

The biggest challenge in 5G access network construction lies in the dense fiber connections between large-scale 5G macro base stations and indoor micro base stations. The complex wiring environment, especially indoor optical fiber wiring, has limited space and puts forward high requirements on the bending performance of optical fibers. The optical fiber conforming to the ITU G.657.A2/B2/B3 standard has greatly improved the bending performance, and can be fixed and bent at the corner of the trace while ensuring the performance.

2. OM5 multimode fiber patch cord can be applied to 5G core network

Secondly, 5G service providers also need to pay attention to the construction of data center fiber optic networks used to store information. At present, the network transmission rate of the data center is gradually migrating from 10G/25G, 40G/100G to 25G/100G, 200G/400G, which puts forward new requirements for the multimode optical fiber cables used for the internal interconnection of the data center. Multimode fiber not only needs to be compatible with existing Ethernet standards, meet the conditions for upgrading to high-speed networks such as 400G/800G in the future, and support wavelength division multiplexing technologies such as shortwave wavelength division multiplexing (SWDM) and single fiber bidirectional (BiDi), At the same time, excellent bending performance is required to adapt to the high-density wiring scenario of the data center.

 3.-diameter optical fiber greatly improves cable density

Due to the complex deployment environment of the access layer and aggregation layer of the 5G bearer network, existing cable pipeline resources are often limited. In order to ensure that more fibers can be accommodated in a limited space, cable manufacturers are working to reduce the diameter of the bundle and optimize the size. Nowadays, many well-known optical fiber manufacturers in the industry have developed micron-diameter optical fibers. For example, Prysmian Group has launched the BendBright XS 180 μm bend-insensitive single-mode optical fiber to meet the needs of 5G connections. The fiber diameter is 180 microns, compared with For conventional optical fibers (fiber diameter is 250μm), the fiber size is reduced by 28%.

Similarly, Corning has launched the RocketRibbon200 ultra-high-density optical cable, which uses SMF-28® 200-micron optical fiber. With the same number of optical fibers as the RocketRibbon optical cable, the diameter of the optical cable is reduced by 15%, effectively saving materials and costs. , improve deployment efficiency.

In addition, YOFC also provides eBay® + 200 micron small outer diameter bend-insensitive optical fiber for 5G networks. While maintaining the use of 125 micron fiber glass, the optical fiber cable reduces the fiber coating from 250 μm to 200 μm , effectively combining optical fiber miniaturization and bending resistance. Under the premise of the same number of optical fiber cores, the outer diameter of the optical cable can be effectively reduced, and in the best case it can be reduced by 50%, which greatly improves the installation density of optical fibers in the pipeline and saves pipeline resources.

4. Ultra-low loss, large effective area optical fiber to extend the length of 5G link

5G optical fiber manufacturers are actively exploring ultra-low loss (ULL) optical fiber technology to extend the transmission distance as much as possible. G.654.E optical fiber is one of the most innovative optical fibers. Different from conventional G.652.D optical fiber used in 10G, 25G, and 100G transmission, G.654.E optical fiber has both larger effective area and ultra-low loss characteristics, which greatly alleviates the nonlinear effect of optical fiber media and improves Optical Signal-to-Noise Ratio (OSNR), generally speaking, OSNR is very susceptible to high-frequency signal modulation in high-speed connections such as 200G and 400G.

5. New fiber optic cables speed up 5G network installation

5G network deployment includes two types of scenarios, indoors and outdoors. The workload is heavy and the environment is complex. Therefore, the installation speed has a great impact on the network construction process. The fully dry optical fiber uses the innovative dry water blocking technology, which can effectively shorten the time required for optical fiber installation and termination. In addition, the air-blown micro-fiber is compact, lightweight, and has a high fiber density, which maximizes the number of cables that can be laid when routing. Due to the air-blown micro-tube micro-cable wiring technology, this optical fiber is easy to install in long, curved, and undulating pipes, which can save manpower and installation time, improve construction efficiency, and reduce laying costs. In addition, in outdoor optical fiber laying, some anti-rat and anti-bird optical fiber cables are also favored.
