Fiber optic circuits

Fiber optic is high-bandwidth transmission medium for data transfer by light modulation in glass or plastic fiber.

Optic cables are used in local computer network infrastructures and have several important advantages against metal cables (twisted pair or coaxial cable). Besides this optic cables are used also for large computer network connections (WAN). The advantages of optic cables in accordance to metal cables are particularly:

• higher transfer capacity
• smaller sizes and less weight
• lower transfer inhibition
• more resistent to electromagnetic interference
• ability to transfer signal for extremely long distances without the need of signal recovery

The most often are optic cables used in large network (WAN) cables and in local networks (LAN) in backbone segments. When we are talking about multi mode fiber optic, they can be used for shorter segments. For longer segments - in tens of km - there is the need to use single mode fiber.

Wireless data communication

Wireless networks are very popular in mobile voice and data communication. They can be in concept optic, infrared or radio.

We don't have to talk about the advantages of wireless local area network (WLAN) for nowadays company intranets enhancement and full scope replacement very long. Not as large distribution in recent past bear on slow standardization, lower bandwidth and more expensive equipment. But normalization and the market looks different now and mainly this year is witness of massive attack of wireless connection in business, at home and on public places.

Latest data wireless networks are developed in many different variants according to range (local, home, personal) and bandwidth (hundreds of Kbps to tens of Mbps). Wireless local area networks (WLAN, according to 802.11b (WiFi)) are quickly going to lead in local communication in companies or at homes.

We offer wireless lines in band 2,4 Ghz and 3,5 Ghz.
