Description

Ethernet - Fiber converters enable connections of Un-shielded Twisted Pair (UTP) copper-based ethernet equipment over a fiber optic link to take advantage of the benefits of fiber which include.

Highlights

Extending links over greater distances using fiber optic cable

Protecting data from hacking, noise and interference upgrade your network with additional bandwidth capacity

Provides you with the flexibility to add fiber on a port-by-port basis

Fast ethernet or gigabit ethernet to multi-mode or single mode

Ethernet to fiber and fiber back to ethernet links

Fiber to fiber links

About The Product

The copper transceiver used in an ethernet-fiber converter transforms the signal from a UTP/RJ45 ethernet link to one that can be used by a fiber optic transceiver. Media converters can connect to various optical fiber cable such as multimode, single mode or single strand fiber cable.

The ethernet-fiber converter is a standalone device with its own power adapter. They convert fixed speed fast ethernet rate converting 10/100 UTP links to fiber connections.

Advantages

Copper-based ethernet connections are limited to a data transmission distance of up to 100 meters when using unshielded twisted pair (UTP) cable. By using an ethernet to fiber conversion solution, fiber optic cabling can now be used to extend this link over distances up to several kilometers.

An ethernet to fiber converter is very useful in environments where high level of electromagnetic interference (both man-made and natural lightning) is present – like in Industries, railway stations, power stations, remote installations etc. The EMI interference can cause temporary or permanent corruption of data over copper-based ethernet links. Data transmitted over fiber optic cable is completely immune to these types of interferences.

Targeted Market Segments

Wind mills – Linking various installations that are kilometers apart

Industrial automation – Connecting machines/equipment in a heavy emi/noise/vibration/pollution/hazardous environment

Larger offices – Connecting servers and client systems that are spread over a larger area where running UTP cables is not feasible/viable/unsafe

Secure data transmission is of prime concern – this product will offer some degree of protection in the Layer - 1 level

Mobile communication/telecommunication/network service providers
