Kylia offers DWDM multiplexers for high-bit-rate metro networks

JUNE 18, 2008 -- The manufacturer provides devices for the bandwidth range from 6 to 100 GHz with up to 48 channels.

JUNE 18, 2008 -- Kylia (search for Kylia), a designer and manufacturer of fiber-optic devices based on free space optics (search for free space optics) technology, offers a range of DWDM multiplexers/demultiplexers to support bit-rate increases in metro networks.

The manufacturer provides devices for the bandwidth range from 6 to 100 GHz with up to 48 channels. Since bit rate is directly linked to bandwidth, various options for reaching the desired bit rate are available: 20x2.5 Gbits/sec; 16x10 Gbits/sec, and more. Any of these solutions are athermal and are currently implemented in the field.

For metro networks where flexibility is as important as bit rate, says the company, free space technology affords all the flexibility features needed to meet this "ultra DWDM" approach. In order to keep transmissions from drifting, Kylia recently delivered a DWDM mux/demux with frequency tunability features. "We have several options to get rid of some laser drifts. We can either make our mics response flat top or we can even widen our natural Gaussian shape. In this particular case, we implemented motors to allow the customer to shift in frequency its nominal DWDM comb of eight times its nominal spacing (8x12.5 GHz). The module was a PM module with a PER better than 19 dB," says Ludovic Fulop, Kylia's production manager.
