Exchangeable Tunable Filters

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

  • Both Fixed and Adjustable are Available

    • Adjustability range >20 nm

  • Low Insertion Loss

    • Depending on the specific filter, losses are from 0.7 dB to 2 dB

  • Good Return Loss

    • >45 dB

Ordering Information for Exchangeable Tunable Filters

Note that two parts are necessary to make a useable exchangeable filter.  Specifications are needed for both the collimator bed (TFM or WTFM) and the filter cartridge.

  1. Collimator Bed (TFM or WTFM) Ordering Protocol

    Use the following definitions to specify the TFM or WTFM (collimator bed).
    TFM-ppp-cc/ccc-bb/a (Example: TFM-SMF-FC/APC-15)
TFM =    Single filter fiber collimator bed
WTFM =    Dual filter fiber collimator bed
ppp =    Fiber type  
  SMF =  Single mode fiber 9/125 for 1310 nm
  PMF =  Polarization maintaining fiber 9.5/125 for 1310/1550 nm
  MMM =  Multimode fiber 50/125
cc/ccc =    Connectors  
  FC/SPC =  FC with SPC (super physical contact) fiber face
  FC/APC =  FC with APC (angled physical contact) fiber face
  SC/SPC =  SC with SPC (super physical contact) fiber face
  SC/APC =  SC with APC (angled physical contact) fiber face
bb =    Wavelength band  
  15 =  1550 nm
  13 =  1320 nm
  1. Filter Cartridge Ordering Protocol

    Use the following definitions to specify the filter cartridge (FC).
    FC-ff-a-b-wwww (Example: FC-PB-1-3-1560)
FC =    Exchangeable filter cartridge designator
ff =    Filter type  
  PB =  Band pass
  SP =  Short pass
  LP =  Long pass
a =    Number of cavities
b =    Fill width half max (fwhm) bandwidth
wwww =    Specify longest wavelength
