10-14 Issue 8.0 July 2002
Transmission Distances 10
FT-2000 OC-48 Lightwave System without
Optical Amplifiers 10
Table 10-10 shows the transmission distances of the FT-2000 OC-48 Lightwave System
without optical amplifiers (for example, the FT-Lightwave Booster Amplifier).
Notes :
1. Standard fiber assumes the following fiber loss (including splice loss) with a dispersion limit of 18 psec/nm
per kilometer:
1.3 µm — 0.45 dB/km
1.5 µm — 0.25 dB/km.
2. Low loss fiber assumes the following fiber loss (including splice loss) with a dispersion limit of 18 psec/nm
per kilometer:
1.3 µm — 0.375 dB/km
1.5 µm — 0.22 dB/km.
3. Dispersion-shifted fiber assumes a 0.25 dB/km loss at 1.5 µm.
4. Only 1.5 µm transmitters will work with dispersion-shifted fiber.
* The dispersion limit applies only to the OC48 TRMTR (A/D 1.5 STD) circuit pack using standard fiber.
The limit is 1800 psec/nm or 100 km.
