Cordless Telephones

With the advent of fiber optics communications LightWave, the focus on technology for long-distance telecommunications service applications. And this is why single-mode glass optical fiber channels most preferred for such programs is not.

Following the increasing demand for higher bandwidth data communications market had risen to the forefront of fiber-optic communications. After several rounds of competition with other technologies, Ethernet is clearlywinner of the LAN.

Silica-based multi-fiber has been approved for a connection at low cost with a combination of optical transceivers based on Vertical Cavity Woon-Emitting Laser (VCSEL).

But this is not the best solution is to broadcast such silica based optical fibers even in environments and home networks or connections.

Why? Plastic optical fiber (POF), with its big heart, which should be in the office and media network at home. Plastic opticallarge core fiber allows the use of economic-injection molded plastic connectors significantly the total cost is lower link.

But the RAF has its own problems. The biggest obstacle is a fiber plastic high signal loss (attenuation). PMMA is used as a basis the guiding light for moving the commercially available index PMMA POF and mitigation is about 100 dB / km. This high damping significantly reduces the programs of the RAF in data communications applications100m.

Here's the good news, though. Developers have found that PF-based amorphous polymer gradient-index plastic optical fiber with attenuation problem of PMMA-based plastic fibers off. Developed PF polymer-based Gradient-Index (GI) POF with attenuation of only 10 dB / km. Based on theoretical calculations, the PF polymer-based GI POF achieve a similar level of attenuation than silica-based 0.3dB/km fiberglass.

With an optimized index of refraction-inPF polymer based GI POF is more than 10Gb / s data transfer rate can be greater than 1 km can be achieved. These are the statistics of loss of polymer PF intrinsic low and low leakage.

Combined with the theoretically possible with high speed and low total cost link, PF Polymer Science-based gradient index plastic optical fiber has a huge potential in fiber optic data communications.
