Dear all,
We're an FSO vendor - as well as our other radio and micrwoave products.
Actually I feel we should pitch in on the LEDs vs lasers - a topic we know
very well:
- LEDs are limited in power and bandwidth (more than 50Mbps at reasonable
power is a real problem for the raw LED devices)
-
It does make you wonder why the ISP in question wasn't multi-homed.
