Fiber Optics Communication

For hundreds of companies in dozens of industries, Linx Networks has provided Fiber Optic Cabling installation services for PONs and other solutions that have met the communication needs of today while preparing businesses for the opportunities of tomorrow. Our team undergoes consistent training to ensure we are constantly up to speed on both the latest fiber optic technologies and the latest communication needs for specific industries and/or applications. Consider the performance, efficiency and TCO advantages of a passive optical network, or PON, a point-to-multipoint, fiber-to-the-user network architecture that employs unpowered optical splitters that enable a single strand of singlemode optical fiber to serve multiple users, reducing the amount of physical cable and active equipment in an installation. Where copper cabling uses electrity to transmitsignal from one end to another, fiber optics use light pulses to accomplish the same purpose. Fiber optic is made of transparent glass core surrounded by a mirror like covering called cladding. Light passes through the cable bouncing off the cladding untill it reaches the other end of the fiber channel- this is called total internal In todays high speed Grade index Muiltimode fiber or step index Single mode fiber is used to improve light trasmission over long distances. Muiltimode fiber has a larger core and is typically used in short run within building. Single mode fiber has a smaller core and is ised in long distance runs typically out side between building

Fiber To the Antenna

FTTA is a broadband network architecture in which optical fiber is used to connect the remote radio head (RRH) to the base station in new antennas, or retrofitted in existing ones, to replace all or part of the coax local loop. One advantage of fiber-optic cable is that it is easier to install because it is lighter than coax cable. Signal integrity and increased energy efficiency are also driving FTTA deployment . Coaxial cables add noise and degrade signal quality, thus requiring tower amplifiers. By placing the RRH at the top of the antenna and generating signals from there, short coaxial jumpers can be used, thus eliminating tower amplifiers. As for power consumption, unlike traditional base stations where power amplifiers must be cooled using air conditioning, RRHs located at the top of a tower can simply take advantage of ambient cooling. Another advantage of optical fiber is that baseband units (BBU) no longer have to be stuck to the RRH. The BBUs can be moved to wherever it is most convenient. Most importantly, FTTA is required to support low-latency, high-speed backhaul and increase traffic bandwidth.

Remote Radio Head

The RRH houses RF component circuitry including analog-to-digital/digital-to-analog and up/down converters. It connects to the base station via an optical interface, provides operation and management processing capabilities and supports multiple inputs and multiple outputs (MIMO).
