SONET Distance Information for RPR/SRP, DPT, and POS/DPT Uplink Cards

The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. Good quality single-mode, short-reach fiber with very few splices can carry an uplink card signal two kilometers.

If your environment requires the signal to travel close to the typical maximum distance (see Chapter 1, “Overview and Specifications”), use an optical time domain reflectometer (OTDR) to measure the power loss.

For SONET/SDH single-mode fiber-optic connections, use one duplex LC small form-factor pluggable(SFP) optical cable (see Figure 3-14) or two simplex optical cables (See Figure 3-13.)

Caution Splicing can degrade cable performance.

Note Single-mode fiber-optic cables are available from various vendors. These cables are not available from Cisco Systems.
