The advantages of optical cable are necessary for the realization and development of optical cable transmission. Compared with the copper wire rate of 1.54MHZ per second, the operating speed of optical cable networks has reached 2.5GB per second.

Bandwidth

From the perspective of bandwidth, the biggest advantage is that optical fiber has a large information capacity, which means that small-sized electronic cables can be used without having to update or enhance the signals in optical fiber cable transmission. Optical fiber cables have a large impedance to electromagnetic noise, such as radio, motors, or other adjacent cables, making them unaffected by electrical noise. From the perspective of long-term maintenance, the maintenance cost of optical cables will be very low.

Transmission Medium

Optical fiber transmission has the advantages of small attenuation, wide bandwidth, strong anti-interference, high safety performance, small size, and light weight. So it has incomparable advantages in long-distance transmission and special environments. The transmission medium is an important factor in determining transmission loss. It determines the distance required for relaying signals. As a transmission medium for optical signals, optical fiber has the characteristics of low loss. The frequency band of optical fiber can reach more than 1.0GHz. The bandwidth of general images is only 8MHz. The image of one channel is sufficient to be transmitted with a core optical fiber. And it is more advantageous in transmitting voice, control signals or contact signals.

The copyright wave in optical fiber transmission is a light wave. Which is an extremely high frequency electromagnetic wave, much higher than the frequency used in radio wave communication. So it is not subject to interference. Moreover, the glass material used in optical fiber is non-conductive and will not produce sparks due to disconnection, lightning strike, etc. So it has strong safety and is particularly suitable for flammable and explosive occasions.

Multimode Optical Cable

Whether domestic or international, the server port rate evolution of users of hyperscale data centers based on cloud computing services is significantly faster than that of traditional enterprise data centers. Traditional enterprises will stably use OM4 multimode optical cables. And more than 90% of the system link lengths are less than 100m.

Hyperscale data center users choose more single-mode optical cables. And 70% of the system link lengths exceed 100m. The development of hyperscale data centers has increased the utilization rate of single-mode optical cables. But multimode optical cables still have their unique advantages. These advantages are the use of lower-cost optical transceiver modules. Lower power consumption and transmission distances that can cover most links in data centers. Therefore, multimode optical cables and multimode optical modules are still very attractive to customers.
