What are the maximum distances using different fiber grades?

This post is meant as an easy reference for when you plan to switch to higher FC or Ethernet speeds or when you’re connecting distant locations and need to order new fiber cables for your rack to rack cabling.

The graphs show the direction where OM-specs are going compared to distances.

The importance of keeping fibers clean

Fiber patch cables seem to be very forgiving, when light shines through everything is great and everybody’s happy, right? Wrong!!!
You shouldn’t underestimate the importance of keeping the ends of patch cables and the SFPs clean, since the actual diameter of a fiber is either 9 or 50 (or even 62.5) mu (micron).

Discussing the challenges of Long Distance Links

Posted by on November 20, 2012 No comments

On ECN (EMC Community Network) together with Jon Klaus, a colleague of mine, I started a new “Ask the Expert” discussion about long distance links and the challenges you might be facing there. I would like to invite you to join the discussion there:

https://community.emc.com/message/690945

If you’d like to discuss anything here, you’re welcome to do so on ECN, but if you also like Twitter there’s a treat for you as we will be having a LIVE “TweetChat” on Monday November the 26th from 19:00-21:00 CET (1PM-3PM EST, 10AM-12AM PST). The URL you can use to filter out the discussion will be http://tweetchat.com/room/EMCATE.
An earlier anouncements about the TweetChat on Thursday the 22nd proved to be badly chosen because of Thanksgiving, a national holiday in the USA. We didn’t see this coming. Our appologies. I will be online on Thursday the 22nd anyway to welcome anyone who didn’t see the new anouncement.

Let’s join the discussion!
