I did a project where I connected a pair of 3550's via SMF and 1530nm CWDM
gigabit adapters between buildings across a campus. For a basic point to
point link between two switches you can use these adapters with out any
other gear. It is when you want to aggregate several adapters/switches over
one pair of fiber between the aggregate set of switches is when you would
need the optical multiplexer.
For lab testing I also had a single set of switches connected via CWDM
gigabit adapters but use Variable Optical Attenuators to reduce the laser's
dbm level since my fiber link was only 12' between the switches. This is
required to prevent burning out the lasers in the gbics.
HTH.

Hi,
As far as I know you can use a switch card with gigabit (such as the
WS-X6516A-GBIC) and depending on the Giga modules you use you are able to
use CWDM or DWDM.
Now, the questions is...how? Someone suggested using the Cisco WDM Series of
CWDM Passive Devices (see
http://www.cisco.com/en/US/products/hw/modules/ps5455/products_data_sheet090
0aecd8029d01b.html
) but I dont really see how. Is there any further configuration to do? Do I
just plug the giga-modules in the passive devices and lay fiber as will??
Please, help much appreciated...this issue is a bit urgent...
Regards,
Fernando
