Applications Include Test, R&D, and Communications
1-Cavity, 2-Cavity, and 3-Cavity Designs
Depending on your transmission type
Very Stable Over Time and Temperature
Advanced YAG welding techniques lead to very good alignment characteristics over time
Low Insertion Loss
Losses are from 1-1.5 dB for fixed filters and 1.5-2 dB for tunable filters (depending on the specific filter)
Good Return Loss
>45 dB for both fixed and adjustable filter series

Ordering Information for In-Line Fixed Filters
Note that two parts are necessary to make a useable exchangeable filter. Specifications are needed for both the collimator bed (TFM) and the filter cartridge.
In-Line Fixed Filter Ordering Protocol
Use the following definitions to specify the in-line fixed filter (ILF). ILF-nnnnB-c-w-x-y-z (Example: ILF-1560B-1-3-S-F-A)
ILF =
In-line fixed filter designator
nnnn =
Center wavelength
c =
Number of cavities
w =
FWHM
x =
Fiber type
S =
Single mode fiber 9/125 for 1310 nm
P =
Polarization maintaining fiber 9.5/125 for 1310/1550 nm
