Intra-Office Telecom
WDM Applications
(Wavelength Division Multiplex),
Datacom, Video Links, or Intra-
Office Telecom Applications. It
emits optical power at 820nm
and detects incoming optical
power at 1320nm, allowing full
Duplex Communication over
one single fiber.
The MF799 uses dichroic
(wavelength-selective)
beamsplitters for maximum
power budget and minimum
crosstalk. Minimum internal
crosstalk is achieved by the
use of wavelength-selective
Detectors. The long wavelength
path meets requirements for
FDDI (ANSI X3T9.5 and ATM
155Mbps.
The MF799 is designed for
multi-mode fiber and optimized
for 62.5/125µm fiber.
