Need to see what happens on your fibre connections?

The solution is called Lambdatap ISMM - the optical TAP in Swiss quality!

Test Access Points

Where data has to be transported reliably, observation of the route is an important element in quality management. And in fibre networks it is very important not to disrupt running services.
For such requirement Lambdatap ISMM has been developed. It is built in permanent in working fibre connections and splits a certain amount of light out of the working path. That part of the light is available to be monitored and analysed actively by external equipment.

Key features are:

Networks interconnect cities, provide people with information and link computers with mass storage systems. Networks are vital today, and they are growing more and more complex. Since they are vital and complex they need to be continuously monitored. In case of a fault, at the latest, technicians need to have access to the full range of information, without any loss, in real time. In fiber links, optical splitters are used to split light and thus data into a working and a monitor part. The monitor light is branched from the signal light. Two splitters are therefore required for bidirectional monitoring (upstream/downstream). High port density and robust handling are essential features as well, particularly in data center applications.

Lambdatap – ISMM

In-Service Monitoring Modules enable a passive test approach to optical networks like LAN, MAN, WAN or SAN.

By splitting the light from a fiber link, the entire data stream can be monitored and analyzed down to the very last bit – in both directions!
The passive component design eliminates the risk of the data stream being affected by analyzers or probes placed at the output of a duplex coupler. Even in case of a test unit failure, this does not impair data transmission. The utilization of In-Service Monitoring Modules, however, supports a wide range of tests.
As measuring tools, they are part of the TAP product group (Test Access Points), which act as a physical optical test interface for use in conjunction with analyzers and probes or topologies. The In-Service Monitoring Module operates independently from the transfer protocols and topologies used.

In-Service Monitoring Modules should be installed in every optical link – they are indispensable, however, for storage links in Storage Area Networks (SAN), for mission critical optical links, e. g. Inter-Switch Links (ISL), uplinks, etc.

For in-depth fault analysis, In-Service Monitoring Modules enable a direct access to the data link – bidirectionally, in real time and uncorrupted.

In combination with intrusion detection systems (IDS), the split data streams can be analyzed and tested for viruses, Trojan Horses and intruders.

Up to three cassettes can be mounted into a 19 inch rack, each fitted with 8 bidirectional ports (optionally SM or MM).
