MF799 Datacom, Video Link, Intra-Office Telecom, WDM Duplex Device Applications MF799 ST • • • • • • • (Wavelength Division Multiplex), Datacom, Video Links, or IntraOffice Telecom Applications. It emits optical power at 820nm and detects incoming optical power at 1320nm, allowing full Duplex Communication over one single fiber. Ethernet 10 or 100Mbps Token Ring Fibre Channel 266Mbps FDDI ATM-SDH/SONET 155Mbps Intra-Office Telecom WDM Applications 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. Features • Full Duplex Communication Over One Fiber • Dual Wavelengths 820/1300nm • Very Small Size • Very Low Internal Crosstalk • Packaged in IndustryStandard ST® Receptacle • Designed for 62.5/125µm Fiber ST Assembly Ordering Information PART # RECEPTACLE MF799 ST -40°C to +85°C The MF799 is designed for multi-mode fiber and optimized for 62.5/125µm fiber.
