a. Fiber loss = 0.25 dB/km. Some spans with span loss more than the maximum value may be
accommodated. Lucent provides network engineering support to optimize WaveStar OLS 40G
systems for actual network. Please contact your Lucent sales representative for more
information.
b. This distance is limited by the dispersion characteristics of standard single-mode fiber (SSMF) 640
X 17 ps/nm-km = 10880 ps/nm).
c. See Table 10-3 on page 10-9, “Engineering Rules for Single-OA System With LEA105.”
