Is Tapping Low Optical Budget Links Making you Pull Your Hair (or the TAPs) Out?

By: Gina Fallon, VSS Product Management

If you have ever had to do split ratio calculations for passively tapping network links, you have a tendency to want to pull your hair out over the mathematical Olympics required. When you have to deal with low optical budgets, it takes the challenge even a step closer to the tipping point where there is no budget left to establish link with the network device and/or probe attached to the passive tap. The most common offenders are 10G & 40G Multimode where Cisco’s 40G Multimode BiDi (40GbaseSR2) budget is so tight it is not even recommended for passive tapping at all.

The solution is to go to active optical tapping. These taps don’t employ optical splitters (which have inherent insertion loss) and actually regenerate the optical signal on both the network and monitor transmit sides. VSS Monitoring offers vBroker Series products with PowerSafe chassis modules which also offer layer 1 Fail Open/Close state configurability if there is power loss or as a manual force Fail Open option during power on and a full range of optic technology support (10G MM, 40G MM, 40G MM BiDi, 40G SM, etc.).

One of the really good things about the new NTMC or Network Time Machine 'Carrier' is that it truly is a carrier grade or enterprise acceptable solution with an OS that is now more hardened via Windows Server 2008R2. Gone are the Windows 7 days....

What not to do with an OptiView and some gotchas!

We get asked many times about “doing” things to an OptiView XG because it uses a Windows 7 Professional Operating System.

Firstly, don’t! If you try to apply common corporate practices of hardening Windows PCs to the OptiView XG, you will break it, full stop!

OptiView IS NOT a Windows desktop machine, the security guys do not and in many cases must not get involved with the unit trying to harden it up as per an organisations' security policy. OptiView must primarily been seen as a tablet based tool for the network engineer, not just another Windows PC.
