4G will provide a guarantee for the global development of optical fiber and cable small and medium-sized enterprises

4G is the abbreviation of the fourth generation of mobile communication and its technology, which is a technical product
that integrates 3G and WLAN and can transmit high-quality video images and image transmission quality comparable to high-definition TV.
Due to its fast speed in the formation of small and medium-sized enterprises in the formation of LAN and network integration has irreplaceable advantages, it is believed that the future development of small and medium-sized enterprises will bring extraordinary experience, which will accelerate the development of enterprises, improve the competitive advantage of enterprises, and provide a strong guarantee
for the global development of optical fiber and cable small and medium-sized enterprises.

LTE investment will also bring more opportunities to the entire communications industry, and the entire industry chain will benefit
.
From the perspective of the industry chain, network planning and design, network coverage testing, network operation and maintenance, etc.
are relatively beneficial.
In terms of the timing of benefits, telecom technology service providers such as network coverage, network planning and network construction will be the first to benefit, and core network access supporting equipment and transmission network equipment manufacturers will also get a piece of the pie
.

The development of 2G and 3G has promoted the rapid development of optical communications, and the data rate of 4G exceeding 100M puts forward higher bandwidth requirements
for optical networks.
The fragmentation of 4G has further promoted the development of
packet transmission technology.
The various network construction caused by 4G has corresponding optical transmission technology to adapt
to it.
In different application scenarios, there are different types of optical cables to adapt
to it.
For example, 4G base station dense distribution points may require optical fiber composite low (medium) voltage cables, while 4G access network integrated base station cabinets, environmentally friendly optical cables for indoor wiring, and new optical cables with good bending resistance may be used to meet the needs
of 4G construction miniaturization.
Eventually, 4G will lead to great advances
in optical transmission networks and equipment, as well as in the standards of optical cables.

There is a misconception that "mobile communication is wireless, and has nothing to do with cables", in fact, wireless is only in the final access part from the base station to the terminal, and other links are achieved
by wire.
Including the connection between RF and base stations, and the transmission between base stations, communication cable products
are required.
The access frequency band used in 4G is higher than that of 2G and 3G, and the coverage radius of the base station is reduced, which inevitably requires more base stations
.
At present, China Mobile's base station backhaul is all realized through the optical fiber network, so as to effectively ensure the transmission quality
of the wireless network.
Subsequently, with the large-scale deployment of TD-LTE, the demand for optical fiber and cable will inevitably further increase
.
From the perspective of the past ten years, the demand of China's optical fiber and cable industry has always changed positively with the capital expenditure of the industry
.
Broadband and wireless construction can drive the demand for optical fiber and cable, and wireless construction has a greater
drive for demand increase.

The arrival of 4G has promoted the demand for optical fiber and cable, but the entire optical fiber and cable market price may not fluctuate
greatly.
In fact, since 2009, due to the rapid advancement of broadband construction and the strengthening of China Unicom and China Telecom in urban infrastructure transmission, the demand for optical fiber market after 2009 has continued to grow rapidly and has not fallen significantly
.
Although optical fiber and cable manufacturers have expanded production, the overall capacity expansion is basically at the same speed as the expansion of market demand, and the pace of expansion of optical fiber and cable manufacturers is basically within
the rational range.
In 2013, most manufacturers will continue to expand their production plans, which will ensure
the balance of supply and demand after 2014.
However, optical fiber and cable companies cannot blindly expand production, otherwise the problem of overcapacity will follow
.

In short, optical fiber and cable enterprises in the 4G era should treat calmly, be aware of the opportunities in the industry, and at the same time treat rationally in the face of opportunities, rationally expand production, and promote the company's profitability level in a stable and orderly manner
.
This is both an opportunity and a challenge
for Hunan Fnetlink.
