This article helps you to get all information regarding fiber modems with all its key features, advantages & applications. Fiber modems usually convert E1, Ethernet, V.35 electrical signal to an optical signal. Generally these modems are used so as to extend V.35, Ethernet or E1 connectivity up to 100km distance. They work in a fractional or transparent mode so as to support Ethernet and V.35 connectivity. These modems offer cost effectual solution when they are used in extending the access network ahead of SDH networks. They are also used in FTTH/FTTP networks. To supply a range of end user data interfaces, these fiber modems are interoperated among each other. These modems are quite reliable and simple. Fiber modems lines are usually installed successfully in thousands of enterprises, government, military facilities and carriers worldwide. There are several advantages and some of the key features related to these modems are: Key features •Fiber modem usually supports V.35/E1/fiber optic interface and Ethernet interface •They support DC or AC power supply options •These modems can interoperate with each other •Can extend V.35/Ethernet/E1 service ranging to 100km •Remote and local loop back is supported •These can operate over multi and single mode fiber •For the loop backs activation, Dip switches are usually available •They also support RS232 interface Advantages •These modems are of smaller size and have lighter weight for quicker deployment •Higher bandwidth intended for better throughput •Less expensive •Better quality usually safe from the electromagnetic interference •Fiber modems are more secure as there is no electromagnetic signature •These have lower loss till 16km repeaterless long distance communication •It increases reliability of link with power supply and redundant uplink •They reduce footprint at central location •Solutions in favor of both copper and fiber for needs of mixed infrastructure at remote location Fiber modems – E1/T1 fiber modem, V.35 fiber modem, Ethernet fiber modem. 1.E1/T1 fiber modem – It is usually a digital transmission linkage which runs at 1.54 Mbps. It provides “twenty four” data channels. This term T1 is interchangeably used with “DSI”. This modem may be configured to either support single or multi mode fiber. 2.V.35 fiber modem – These modems work in fractional or transparent mode so as to support V.35 connectivity. They are quite cost effective which might be used in FTTH/FTTP networks. 3.Ethernet fiber modem – So as to offer various data interfaces of end user, these modems can be incorporated among each other. They are used for LAN bridging. Applications 1.LAN bridging 2.Public switch to PABX/ISDN switch 3.Network to client 4.2.048 Mb/s unstructured and structured 5.P2MP and P2P applications This article helps you to get all information regarding fiber modems with all its key features, advantages & applications.
