MF699
Ordering Information 13330.11, duplex package
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 820nm and detects incoming optical power at 1320nm, 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 by the use of 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.
