Technical Specifications
10-12 Issue 8.0 July 2002
FT-2000 OC-48 Lightwave System and
Wavelength Division Multiplexing Systems 10
The FT-2000 OC-48 Lightwave System is also designed to meet the OC-48 loss budget
specifications shown in Table 10-8 when operating with wavelength division multiplexing
(WDM) systems.
*Transmit and receive powers are referenced to points S and R as shown in Figure 10-1.
†These values include transmitter/receiver connectors @ 0.7 dB each (worst case) and the system margins.
‡ The receiver sensitivity and maximum received power values are measured at a BER of 1x10
-10
.
§ The 1.5 µm Standard Performance optics is dispersion limited to 92 kilometers.
¶ These values assume that the maximum received power limitations are not exceeded.
