Tunable Optical Filters

100 and 50 GHz tunable filters feature a low insertion loss and a high adjacent channel isolation to minimize the attenuation of the signal transmitted and prevent multi-channel crosstalk respectively. The tunable filter modules are controlled by a digital interface to simplify operational control and system integration.

Features

  • Wide tuning range
  • Low insertion loss
  • High adjacent channel isolation

Applications

  • Channel filtering on 100 GHz ITU spacing
  • Channel filtering on 50 GHz ITU spacing
  • Edge ROADM
ETOF

A Tunable Optical Filter is an optical device whose passband can be moved along the spectrum, allowing the transmission of a selected wavelength band.

II-VI ETOF is a compact and low power consumption device based on a dual ethalon cavity, exploiting the Vernier effect and tunable over 5 THz band.

Features:

  • Wideband
  • No moving part
  • Small size
  • C-Band and L-Band options available
  • Low cost

 

Applications:

  • Side ASE suppression
  • Single channel ASE clean-up
  • Post-TX ASE filtering and spectral shaping
  • Pre-RX ASE filtering
  • Channel tracking
  • Ideal for subsystem/transceiver integration
Mini-MTOF

frequency  to be transmitted over a wide 5THz tuning range. Its footprint  is so small that it can fit into a CFP2/CFP4 form factor package. VOA function is also integrated for fine power regulation.

Features:

  • Continuously tunable
  • Simple control
  • Compact
  • Integrated VOA for fine power adjustment

 

Applications:

  • Side ASE suppression
  • Single channel ASE clean-up
  • Post-TX ASE filtering and spectral shaping
  • GFF & VOA substitution in amplified Tx
  • Pre-RX ASE filtering
  • Channel tracking
  • Optimized to be integrated inside High Bit Rate transceiver form factor
MTOF

The MTOF is a Tunable Optical Filter whose passband can be moved along the spectrum through the combination of a MEMS and a grating in order to select the wavelength range to be transmitted. II-VI MTOF is a continuously tunable filter operating over 5THz in C-Band; the L-Band variant is also available.

Features:

  • Continuously tunable
  • Simple and fast control
  • Compact

 

Applications:

  • Side ASE suppression
  • Single channel ASE clean-up
  • Post-TX ASE filtering and spectral shaping
  • GFF substitution in amplified Tx
  • Pre-RX ASE filtering
  • Channel tracking
  • Ideal for subsystem/transceiver integration
