Description
Used in combination with the
MF799, the MF699 Duplex
Device is designed for WDM
(Wavelength Division Multiplex),
Datacom, Video Links, or Intra-
Office Telecom Applications. It
emits optical power at 1320nm
and detects incoming optical
power at 820nm, allowing full
Duplex Communication over
one single fiber.
The MF699 uses dichroic
(wavelength-selective)
beamsplitters for maximum
power budget and minimum
crosstalk. Minimum internal
crosstalk is achieved with
wavelength-selective detectors.
The long wavelength path meets
requirements for FDDI (ANSI
X3T9.5) and ATM 155Mbps.
The MF699 is designed for
multi-mode fiber and optimized
for 62.5/125m fiber.
