Short Answer is “It depends, but usually yes.” Long answer follows with a discussion of launch power, receiver sensitivity, and cable losses.
Can Fibre Optic Ethernet Cables Be Longer Than the Standard ?
Webinar on SDN & OpenFlow – Sponsored by Big Switch – Open Attendance

I’m pleased to announce that Big Switch have agreed to sponsor SDN & OpenFlow Webinar on February 7th, 2012 and that the event will be free and open to anyone to attend.
Are you a Network Architect or Designer ? Are you responsible for strategy, long term vision, or simply keeping track of upcoming technologies ? If so, you will need to know more about OpenFlow and Software Defined Networking and how it impacts the future of Networking in software and hardware.
And now, thanks to sponsorship from BigSwitch Networks, anyone can attend.

Ethernet Jumbo Frames, Full Duplex and Why Jumbo Frames Are 9000 Bytes)
I’ve been doing some research into Ethernet and the use of Jumbo frames for some content I’ve been writing and come across something interesting. The documents state that Jumbo frames can only be used on Full Duplex Ethernet connections.
Modular Data Centre – On the Highway
Saw this modular data centre rolling down the highway today.
Problems With Cat6A Cables in Data Center
I was reading a white paper by Panduit that claims that 10GBaseT is suitable for use. I’ve been critical of Cat6A cable and believe that it’s not suitable for data centre use.
Cisco Nexus 5000 / 2000 Pricing Bundles and Fabric Extension Transceivers (FETs) vs 10GbaseSR SFPs.
Recently I noticed that Cisco is selling “Fabric Ethernet Transceivers” for the Nexus switch family. Some research shows that these are replacements for 10GBaseSX SFP modules. Importantly, it’s cheaper to install new cabling than to buy 10BaseSR SFP+ modules.
Requirements Terminology – Defining MUST, SHOULD and MAY
One of the problems of working with the PRINCE2 practitioners is that the people tend to get highly focussed on definitions in the Scope of Works. A Scope of Works defines what the deliverables the customer is to received.
The problem with a Scope of Works is that it is usually prepared before the work is started and/or fully understood. maybe you have a Gap Analysis, or a Consulting Reports or a Requirements Document to setup the initial engagement (every company has their own name of the same thing).

Soft Switching Fails at Scale
There is a significant camp of software developers who are developing software switching solutions for hypervisors. Which is nice, I guess. The use of software switching in the hypervisor has some good points but, in my view they are heavily outweighed by the bad. I present the use case, and show that software
