C Form-factor Pluggable

October 2, 2011

The C form-factor pluggable (CFP) is a multi-source agreement to produce a common form-factor for the transmission high-speed digital signals. The c stands for the Latin letter C used to express the number 100 (centum), as the standard was primarily developed for 100Gb Ethernet systems.

An optical communications repeater

October 2, 2011

An optical communications repeater is used in a fiber-optic communications system to regenerate an optical signal by converting it to an electrical signal, processing that electrical signal and then retransmitting an optical signal. Such repeaters are used to extend the reach of optical communications links by overcoming loss due to attenuation of the optical fibre and distortion of the optical signal. Such repeaters are known as 'optical-electrical-optical' (OEO) due to the conversion of the signal. Repeaters are also called regenerators for the same reason.

All-Optical regenerator

October 2, 2011

An alternative method of regeneration is through all-optical without requirement to convert back and forth. Using Non-linear optical fiber allow designers to use nonlinear effects of frequency shifting and frequency generation effects for regeneration. The key advantage of all-optical regeneration is power efficiency provided by the device, and simple integration into an optical network.

Electronic and Optical regeneration

October 2, 2011

Due to the high data rates that can be achieved with optical systems, OEO repeaters are expensive to implement as electronics to handle those high data rates are expensive and difficult to construct. Also, since one repeater is required for each wavelength, and many tens of wavelengths may be transmitted down a single fibre, a lot of equipment is required for each fibre.

What is the Fiber-to-the-Home (FTTH)

October 2, 2011

As a medium for telecommunications, fiber optics is much faster than conventional wire, because it uses light instead of electricity to send information.

What is the fiber optic?

October 2, 2011

The invention of the laser in the early 1960s spawned a field of engineering known as optoelectronics, which grew steadily in the 1980s and 1990s. Many engineers believed that the laser would be useful for transmitting information through the air, but they soon learned that clouds, rain, and other atmospheric conditions sometimes blocked the beam. An alternative was to send laser light along glass fibers (similar to the way electric signals are sent along copper wires).
