1 – Description
Thanks to its flexible bulk grating technology, KYLIA is able to propose the most complete DWDM
mux/demux product range :•up to 48 channel•

any spacing from 6.25 GHz till 400 GHz•

S+C+L+U band (1460nm to 1675nm) or around 1310nm•Flat Top shape or specific shape option•PM option

All KYLIA mux/demux products are passively athermal.
Since 1998, KYLIA MICS product is deployed on the field by system vendors, for metro, long haul andsubmarine networks.
MICS is qualified to TELCORDIA 1209 and TELCORDIA 1221.

2 – Technology
KYLIA’s MICS are made using our proprietary Bulk Grating Technology (BGT). This method uses acombination of individual micro-optical elements arranged in a free-space architecture. The grating itself is adiffractive element that enables angular separations of the wavelengths, while lenses and prisms allow
component designers to couple ligt into and out of fibers.
BGT lends itself to the manufacture of naturally athermal devices. Since the light propagation is throughinert gas, the thermal drifts are very low and can reach a drift level of less than 1 pm/°C.
Thanks to the versatility of our technology, we are able to propose to most complete range of DWDM
Mux/Demux, with spacing from 6.25GHz till 400GHz.

DWDM MUX/DEMUX

6 – Flat Top shape and specific shape options
KYLIA provides Flat Top shape MUX/DEMUX. On our Flat Top MICS, the BW @-1dB and BW @-3dB are wider
than for a Gaussian shape MUX/DEMUX but the IL are higher.
We also propose customized shape according to customer requirement, for instance :•••shape “between” Flat Top and Gaussian in order to provide the best compromise between BW andIL
high crosstalk (40dB guaranteed)
Gaussian shape with wider BW (then lower crosstalk)

Mux/Demux 37.5GHz spacing with BW @-1dB > 19GHz

Mux/Demux 50GHz spacing with XT > 38dB

7 – PM option / mini-size PM MICS
7.1 – Bulk grating technology PM mux/demux
PM option is available for each product of KYLIA mux/demux range. PM mics exhibits the highest PER on themarket (19dB).
Customers can choose between two configurations :19dB PER configuration
Using a polarization filter, KYLIA guarantees a PER >19dB.
In the configuration, the mux/demux can only be
used with input beam polarization oriented along
the slow axis.

15dB PER configuration
Without polarization filter, KYLIA guaranteed a PER> 15dB.
In the configuration, the mux/demux can be usedwith input beam polarization oriented along bothaxis, or evan as a SM mux/demux.

7.2 – Thin Film Filters PM mux/demux
KYLIA also propose a DWDM PM mux/demux based on 100GHz or 200GHz TFF (Thin Film Filters) integrated
into a mini-size packaging.

9 – Tunable Mux/Demux
Tunable Mux/Demux (TMICS) is the solution for emulating any DWDM Mux/Demux by tuning the spacing
and the freqency range.
TMICS is available in manual version (micrometer heads)and motorized version (piloted actuators).
With the motorized option, spacing and frequencies are controlled using a user friendly software for active
setup and fast tunability.
