We run the SR4 optics for in-rack cabling, because they are about 4X 
cheaper than all the single-mode options.

We have been heavy on the LR4 optics, but are now starting to test (and 
if happy, switch to) the FR units, as they are even cheaper than the LR4 
option.

The DR options don't make much sense for us, because we prefer the SR4 
for in-rack cabling, and given how large data centres are nowadays, 500m 
might not enough to interconnect with customers.

But for un-amplified Metro-E deployments, we are looking forward to 
testing Adva's 100G-ZR, which is also a single lane optic.

Mark.
