Notes:

1.These are unfiltered 20%~80% values.

2.SMF-28 fiber used. 80 km represents 1600ps/nm at 1610nm. Measured at 2.488 Gb/s with a PRBS 223-1 pattern at a BER<10-10.

3.The sensitivity is provided at a BER of 1×10-10or better with an input signal consisting of 2677Mb/s/OC-48/2X FC/GbE/1X FC/ OC-12/OC-3, 223-1 PRBS and ER=9dB.

4.2.488 Gb/s BER<10-10with PRBS 223-1. Does not include dispersion penalty.
