How can I make fiber optic cables?

Question

Hi,I want to design a background looking just like this, but with red colored cables and a black background. I downloaded this image and used replace color to change the cables to be red, however that leaves an ugly blur around the cables and I want to have a straight black background with no gray/blue hue, so I think I need to recreate the image myself. I've tried the pen tool a lot and I can't seem to get it just right. Are there any tricks or tips to getting this look with an image?Thanks!

If you want to make it from scratch1. Draw some curves with then pen tool (I've only drawn 3 for this demo)2. Set a soft round brush with shape dynamics and flow set to Fade3. Stroke the path with the brush4. Use the ellipse tool to add white circles5. If you want a glow you could paint it on a new layer or use layer styles as belowDave

Like this:That image has a blue haze and there is banding in there changing the blue to red with any adjustment will have banding in the haze area.
