RS-232/485/422 to Fiber Converter
(SS：single mode single fiber)
Introduction:
Model277 is one kind can offer RS-232/485/422 serial port carry
transparent optic fiber modem of transmission to get end to user, no
need patch cords set up, switch over automatically, and can detect
and examine the signal speed automatically, zero delays time to
transmit automatically.
Model277 adopt optic fiber transmit, have
isolate protection, data privacy is fine, working steady, data, such
threats to communication equipment as the wave is welled up and
interfered with electromagnetically that the effective one has
prevented the abominable environment from being struck by
lightning, can work in the abominable and dangerous environment
reliably.
Can be used in occasions such as various industrial control, course
controlling, traffic controlling and intellectual district , especially
suit the bank, electricity and
interfering with environment
department
and
system
with
the
special
requirement
electromagnetically.
