MetroWAVE-TAP - Optical Fibre TAP

What is a TAP? A TAP (Traffic Analysis Point or Traffic Access Port) is a hardware device that provides access to traffic flowing on a physical connection between two or more points within a network. The TAP usually is located in the link between network devices, so the connection from point A connects to the TAP and then from the TAP to point B. The TAP provides a mirrored output of the data flowing between to network ports. Three important features of a TAP: * The TAP provides a mirrored output of the data passing through the device * The data passing through the TAP cannot be modified or degraded by the monitor * The TAP doesn't affect the passing data, so monitoring is done without disruption, requires no power and no electrical components. When installed correctly a TAP can provide access to data flowing across the network, does not allow data to be modified or corrupted and do not represent a point of failure. Metrodata offer two Optical Fibre TAPs: MetroWAVE: TAP-MM - a multimode inline Optical TAP MetroWAVE: TAP-SM - a singlemode inline Optical TAP Our Optical Fibre TAPs are unpowered passive devices for highest possible reliability that support full line rate throughput supporting network speeds from 10Mb to 10Gb and provide monitoring per port. The MetroWAVE-Tap operates by performing a 2-way passive optical split of each input fiber port at the front panel, with one path being returned to the front panel pass-through output port and the other path being directed to the rear panel monitor port. A 50/50 optical power split is normally provided between pass-through and monitor ports, optimised for short-haul fiber applications, however other split ratios are available on request.
