Last week I was working through the verification process for one of our certification courses, delivered under license, by our partners in the USA, and I was delighted by this feedback on a course...
Some days make you think about capacity and performance more than others. The case for lighting up dark fibre with your own communications equipment can be very compelling: virtually unlimited capacity flexibility greater control...
In this blog I’ll adopt a slightly different approach and introduce you to some of the characters that we use in the case studies on our training courses such as the Certified Optical Network...
Most of us are familiar with the OMn labels that we use to talk about the different performance grades of multimode fibre. But things are changing! It’s time to finally say goodbye to some old faithfuls and time to introduce the new kid on the block, because it looks as though he might be staying around a while…
The new style of 100G CFP pluggable optics module builds on the 2nd Generation 100G Ethernet standard that was published in 2015 and uses four pairs of singlemode fibres each transmitting 25Gb/s of data using tuneable lasers in the C-band. This is an interesting halfway house between 10G wavelengths and the very expensive coherent 100G solutions using DP-QPSK. Because the module has no electronic dispersion compensation then it is necessary to do the dispersion compensation optically.
The last eighteen months have certainly been long and challenging, but my recent hospital trips “100 days” after my stem cell transplant have now had positive outcomes. At St. James I learned that the stem cell...
Health update The main event in the treatment of my Myeloma is now completed, with high dose chemotherapy followed by my stem cell transplant carried out at St. James Hospital in Leeds at the...
It is now been more than a year since my diagnosis with myeloma. I am scheduled to be admitted to Saint James’s Hospital in Leeds on Tuesday 24th March for a stem cell transplant.
If you’ve been following this blog, then you might be expecting an update on how the stem cell treatment is going. Unfortunately, the test results from the last cycle of induction chemo and the...
It’s now been nearly since six months since one of my vertebrae collapsed and the subsequent diagnosis of Myeloma as the cause of my weakened bone structure. The next stage in my treatment gets a bit more intensive. This is the stem cell treatment.
On Thursday 27th Feb, whilst running a training course in Ipswich, what I thought had been a niggling, muscular-type back pain took a dramatic turn for the worse. My back pain was so bad...
Welcome to my blog!
I’m generally pretty well known for having an opinion on all things to do with fibre optics, optical networking, training and standards.
I’ve been involved with fibre optics for more than 30 years and I'm passionate about promoting, and contributing to, professionalism in our industry.
