MT-612A-ST BLACK BOX, MT-612A-ST Datasheet - Page 2

• Manufacturer Part Number: MT-612A-ST
• Description: T1 F/O LINE DRIVER ST 1.2 MI.
• Manufacturer: BLACK BOX

If you need to move data
at T1 or E1 speeds, but
you don’t want to (or
can’t) use a T1/E1 line to
do it, a pair of line drivers
and a spool of fibre cable
will—with no worries
about data-line tapping,
surges, or interference.
