FT-2000 OC-48 Lightwave System and the
FT-Lightwave Booster Amplifier 10
Table 10-11 shows the transmission distances of the FT-2000 OC-48 Lightwave System with
the FT-Lightwave Booster Amplifier.
Notes :
1. This dispersion limit applies only to 1.5 µm STD and LBA performance transmitters used with standard fiber.
2. Standard fiber assumes a dispersion limit of 18 psec/nm per km. It also assumes a fiber lo
(including splice loss) of 0.25 dBm/km at 1.5 µm.
3. Dispersion-shifted fiber assumes a 0.25 dB/km loss at 1.5 µm. On dispersion-shifted fiber, both versions
of the 1.5 µm transmitters support the same distance.
4. The 1.5 µm LBA transmitter is screened for dispersion.
