Through the use of TDM modules, transmission capacity of optical channels will<br />
be better utilized. This approach also applies to services with lower bandwidth<br />
than 10G. MICROSENS provides for the 10G Platform a 2-fold Gigabit TDM, with<br />
this two Gigabit Ethernet or Gigabit Fiber channel services can be aggregated<br />
to one optical OC-48/STM-16 channel.<br />
With the TDM method, the two Gigabit channels remain isolated from each other,<br />
so that there is no access between the two services. For xWDM applications the<br />
line interface can be fitted directly with a „coloured“ SFP transceiver. Optionally,<br />
the module is available with line protection functions and RMON.<br />
This Gigabit TDM is also available as a double card with two Gigabit TDMs,<br />
which can achieve higher port densities. One module can generate two OC-<br />
48/STM-16 channels with 4 Gigabit services (Gigabit Ethernet or Gigabit Fiber<br />
Channel) in total.<br />
In an optional mode of operation of this dual module, a line protection function<br />
for one aggregated OC-48/STM-16 channel (two Gigabit services in, and 2x OC-<br />
48/STM-16 protected outgoing) can be realised. The dual card also includes an<br />
integrated 10 Mbps communications channel (DCC) for network management.<br />

In another TDM module a 1 Gigabit Ethernet service can be generated from<br />
4x Fast Ethernet, 4x OC-3/STM-1 or 1 x OC-12/STM-4. This signal at 1.25 Gbps<br />
corresponds to the characteristics of Gigabit Ethernet and can therefore again<br />
be combined with other modules of the 10G platform<br />
