Note 1:
The Transmitter Center Wavelength “x” is as specified by the customer. The current available
wavelengths are: 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm. Please see the “Product
Selection” section on page 2.
Note 2:
Parameters are specified over temperature and at end of life unless otherwise noted.
Note 3:
All parameters are measured on a Finisar GBIC Evaluation Card unless otherwise noted.
Note 4:
Dispersion penalty measured in loop back. Data rate and pattern used same as specified for
Optical Input Power. Measured at BER= 10
-10
. Fiber used is SMF-28. Exact dispersion (ps/nm) will
vary depending on wavelength of device under test.
