In a different building? A different
campus? Or would you just like to
make a connection at T1, E1, T3,
or E3 speeds without handing
your entire budget to a telco for
a subscription to digital service?
Drivers can pass data to each
other at full speed across multi-
mode or single-mode fibre optic
cables. Not only does this solve
device-placement problems, it
does so with optical links that
aren’t susceptible to tapping,
noise, and other hazards of
electrical communication.
MT653 product code prefixes
transmit and receive data on the
1300-nm wavelength into as much
as 23.6 miles (38 km) of single-
mode cable. MT651 models
transmit and receive at 850 nm
into as much as 1.5 miles (2.4 km)
of multimode cable.
