Fiber Pigtail is approximately the size of four Category

When 450 Category 5e cables are bundled together, they are roughly 5.3 inches in diameter. As noted earlier in this chapter, the 144 optical Fiber Pigtail is approximately the size of four Category 5e cables bundled together. The Category 5e bundle thus has a volume roughly 112.5 times greater than the 144 optical fiber ribbon cable. In other words, Category 5e bundles need 112.5 times more space in the conduit than the 144 optical fiber ribbon cable.

This comparison we just made is very conservative. This distance we used was kept very short and the transmission rate for the optical fiber was kept low. We can get even a better appreciation for the cable size reduction fiber optic cable offers if we increase the transmission distance and the data rate.

In this comparison, let’s increase the transmission distance to 1,000m and the data transmission rate to 10Gbps. The bandwidth of a copper cable decreases as distance increases, just as with fiber-optic cables. Because we have increased the transmission distance by a factor of 10, it’s fair to say that the Category 5e cable bandwidth will decrease by a factor of 10 over 1000m.

Don't twist and exceed bend radius of cable: Twisting the fiber can limit its efficiency by stress on fibers and it should not be practiced during lightning application. Fiber optics cable can be broken if bend radius is exceeded. Bend radius must be twenty times smaller than cable diameter and final installation bend must be ten times smaller than its diameter.

Special attention for pool lightning: Fiber optics is waterproof and can be arranged in different patterns for pools and other underwater application. However, safety must be considered before installation. Be cautious about electric current and always dry the pool for installing fiber lightning. Also, test the light box before installation and place them carefully inside the light fixture. Use of proper tools, accessories and splicing method will help you to achieve desired and hassle free installation.

With a reduction in bandwidth by a factor of 10, we will need ten times more Category 5e cables to equal the old 2.5Gbps performance. In other words, we need 4,500 Category 5e cables bundled together. In this comparison, however, the bandwidth has been increased from 2.5Gbp to 10Gbps. This means we have to quadruple the number of Category 5e cables to meet the ban width requirement. We now need 18,000 Category 5e cables bundled together. Imagine how many Fiber Distribution Hub we would need if the transmission distance increased to 80,000m. We would need whopping 1,440,000 Category 5e cables bundled together.
