OFC Fiber Optical cable is mainly using long distance purpose Ex: Plant Interface Building to Control Room.
• SPEED: Fiber optic networks operate at high speeds - up into the gigabits
• BANDWIDTH: large carrying capacity
• DISTANCE: Signals can be transmitted further without needing to be "refreshed" or strengthened.
• RESISTANCE: Greater resistance to electromagnetic noise such as radios, motors or other nearby cables.
• MAINTENANCE: Fiber optic cables costs much less to maintain.
OPTICAL CABLE TWO TYPE:
1.Single Mode cable:
It is a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width. Synonyms mono-mode optical fiber, single-mode fiber, single-mode optical waveguide, uni-mode fiber.
Single Modem fiber is used in many applications where data is sent at multi-frequency (WDM Wave-Division-Multiplexing) so only one cable is needed - (single-mode on one single fiber)
Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core than multimode. The small core and single light-wave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.
2.Multi-Mode cable:
It has a little bit bigger diameter, with a common diameters in the 50-to-100 micron range for the light carry component (in the US the most common size is 62.5um). Most applications in which Multi-mode fiber is used, 2 fibers are used (WDM is not normally used on multi-mode fiber). POF is a newer plastic-based cable which promises performance similar to glass cable on very short runs, but at a lower cost.
Ethernet cables:: are the standard cables commonly used to connect a modem to a router, and, likewise, to connect a router to a computer’s network interface card (NIC).
This is mainly using short distance application.
Ethernet Types: category(CAT) 3,5,5c,6,6a,7.

FOC - Fibre Optic Cable is used for Long Distance Communication. (Example- Communication Between DCS controller and any third party device. DCS Controller in Control room and the WTP PLC Panel) so here it is used.
ETHERNET - is used inside the control room, in between the controller and Ethernet switches.
