Calculation of S-type optical cable length
The distance in fiber optics is calculated using the following formula: [ text {Distance (km)} = frac {text {Speed of Light in Fiber (km/s)} times text {Round-Trip Time (s)}} {2} ] Where: Speed of Light in Fiber ≈ 200,000 km/s (depends on the refractive index of the. Reel count is ceil (Total ÷ ReelSize), and the rounded order length equals Reels × ReelSize. There are a number of ways to tackle the problem of determining the power requirements for a particular fiber optic link. 957 specifies the characteristics of optical systems operating at 1 300 nm and suitable for transmitting the bit rates of the synchronous digital hierarchy (SDH) up to STM-16. GIS Length + Slack Loop Length — This method takes the length of the cable as drawn in the GIS and adds any length stored in slack loops, risers, or other point features that represent additional cable.
