The construction of 5G will bring huge fiber demand. 5G networks require low latency, wide coverage, and massive connections. This puts forward new requirements for the transmission network in terms of bandwidth, capacity, latency, and networking flexibility, which also boosts The increase in the number of base stations.
Base stations need to use optical fibers to connect, and a large number of base stations require a large number of optical fibers and cables. Therefore, the demand for optical fibers and cables will greatly increase. Next, Yitianguang Communications will talk to you about which optical fiber will become a hot demand for data centers and 5G?
One, G.654E fiber
G.654E optical fiber is mainly used in long-distance communication trunk lines. Its advantage is that G.654E is of great significance for the establishment of ultra-high-speed backbone network systems and compatibility with existing systems. As early as 2018, China Mobile organized a pilot test of the G.654.E optical cable on the existing network. Compared with G.652.D, the link attenuation of G.654.E was improved by about 0.02dB/km on average, and the attenuation of the optical cable itself was improved by about 0.02dB/km on average. 0.02dB/km, consistent with expectations. In addition, compared with the same cable G.652.D, G.654.E has an increase in the OSNR margin of the same rate system (1.82-2.78dB), and the incoming fiber power has an increase of about 1dB.
Different from conventional G.652.D fiber, G.654.E fiber has both a larger effective area and ultra-low loss characteristics, which greatly alleviates the nonlinear effect of the fiber medium and improves the optical signal-to-noise ratio (OSNR). ), with anti-microbending performance.
In addition, compared with the traditional G.652 optical fiber, G.654.E optical fiber has obvious advantages in non-electric relay distance, which can extend the transmission distance of non-electric relay and reduce the setting of relay stations.
However, the shortcomings of G.654E are that the process is difficult and the yield is low, which makes the price high, which affects large-scale use. Due to the amount of optical fiber used, backbone network lines account for a relatively low proportion, and most of the optical cable lines are in metropolitan area networks and access networks. Therefore, in actual applications, G.652D fiber is still used in large quantities, and G654E fiber is only used in necessary scenarios.
Two, OM5 fiber
In terms of data centers, the rise of cloud computing and big data, the arrival of the 5G era, and the application of artificial intelligence in various fields are all promoting the transformation of the data center industry. Data centers are increasingly demanding bandwidth. The construction of next-generation data centers requires lower cost and wider bandwidth transmission media. In this context, OM5 fiber and few-mode fiber will usher in new demand growth points.
OM5 fiber has the following advantages:
1. Strong compatibility and interoperability: OM5 fiber patch cord can support traditional applications like OM3 fiber patch cord and OM4 fiber patch cord, and it is fully compatible with OM3 and OM4 fiber patch cords and has extremely strong interoperability. E-Tian multimode fiber and VCSEL have the advantages of low link cost, low power consumption, and higher availability, making it the most cost-effective data center solution for most enterprise users.
2. Reduce cost: OM5 fiber patch cord draws on the wavelength division multiplexing (WDM) technology of single-mode fiber, extends the usable wavelength range during network transmission, and can support 4 wavelengths on a single-core multi-mode fiber. The number of fiber cores is reduced to 1/4 of the previous one, which greatly reduces the cost of network wiring.
3. Strong scalability: OM5 fiber patch cords can combine shortwave wavelength division multiplexing (SWDM) and parallel transmission technology in the future, and only need 8-core wideband multimode fiber (WBMMF) to support 200/400G Ethernet applications;
OM5 fiber optic patch cords give strong vitality to ultra-large data centers. It breaks through the bottleneck of parallel transmission technology and low transmission rate used in traditional multimode fiber. Not only can it use fewer multi-mode fiber cores to support higher-speed network transmission, but because it uses lower-cost short-wavelength wavelengths, the cost and power consumption of optical modules will be much lower than single-mode using long-wave laser light sources. optical fiber. Therefore, with the continuous improvement of the transmission rate requirements, the use of short-wavelength division multiplexing and parallel transmission technology will greatly reduce the cabling cost of the data center. OM5 fiber optic patch cords will be 100G/400G/1T super large There will be broad application prospects in the data center.
3. Few-mode fiber
Few-mode fiber (FMF) is a fiber whose core area is large enough to transmit parallel data streams using several independent spatial modes. The upgrade of data center bandwidth will boost the growth of demand for fewer-mode optical fibers. Few-mode fiber realizes multiplexing by increasing the mode of the light beam propagating in the single-core fiber, and the demand for energy consumption is not significantly increased under the premise of increasing the capacity.
At the same time, the on-site use of few-mode fiber is basically compatible with the existing on-site use of single-mode fiber, and the complexity of its use has not increased significantly. Experts said that the rise of 100G/400G data centers will promote the increase in the application of few-mode optical fibers, and will occupy a place in optical fiber transmission systems in the future.
The construction of 5G networks and large-scale data centers not only promotes the growth of the demand for optical fibers and cables, but also increases and improves the functions of optical fibers and cables to adapt to different scenarios. As a homogenized product, optical fiber and cable may become a new breakthrough in the industry in the context of highly competitive business.
