COMMUNICATIONS COMPONENTS
Miniature Variable Attenuator
MV50 Series
Key Features
• C+L or 1310 nm band operation
• Excellent wavelength dependence and ripple
• Low PDL
• Improved thermal stability
• Compact size
• Single-channel or multichannel applications
Applications
• Power equalization in multichannel,
optically amplified networks
• Power control into narrowband
wavelength division multiplexers
(WDMs) and configurable networks
• Power control into receivers
For the increasing bandwidth demands of today’s networks, JDSU has now
improved on the existing MV50 by allowing for 1310 nm operation, in addition
to the C or L bands. As a next generation-version of the MV47, the MV50 offers
excellent wavelength dependence and ripple, low polarization dependent loss
(PDL), and improved thermal stability. The MV50 series of attenuators provides
an economical solution to managing optical power.
Identical in footprint (the MV50 can be substituted for the MV47) and similar in
design concept to the MV47, the MV50 uses an advanced graded neutral density
filter as its attenuating element. Reflective optics permit same-side jumper exit
and enable easy panel mounting. Attenuation is controlled by turning an
adjustment screw.
Excellent wavelength dependence and ripple facilitate single-channel or
multichannel power equalization, making the MV50 ideal for dense wavelength
division multiplexing (DWDM) systems.
