Frequency Translation Products
FX-200
Description:
The FX-200 is a dual output frequency translator which is used to translate
one of two different input frequencies greater than 1 MHz to one of two dif-
ferent output frequencies between 77.76 MHz and 777.6 MHz. All the major
FEC rates are supported such as 15/14ths and 255/237. This unit can also
support switching from 10.0 G to 10.3125 G, or even OC-n to 10 GigE.
Applications:
• SONET/SDH
• DWDM
• FEC (Forward Error Correction)
