"IBM says around 80 per cent of the fibre links used in data centres and supercomputer installations are less than 50 metres long"
Yes, but it's also cheap and easy to pull or blow new fiber.
While there are politicians in Australia willing to argue that you can't predict the future capacity of fibre, IBM is doing just that, publishing an experiment that suggests the low-cost multimode fibres used for short-haul data centre links will support years of speed improvements. What's interesting in this announcement isn' …
I agree with one of the comments, what OM fibre did they use for the test? The real cost will be the VCSEL's and will the equipment/interfaces on each end support them. I would venture to say that the VCSEL used will be IBM exclusive and not work with any other brand.
Extending the life of the infrastructure is something all IT Infrastructure groups are looking for, but at some point you have to bite the bullet and upgrade the infrastructure anyway.
