| MF799 Datacom, Video Link, Intra-Office Telecom, WDM Duplex Device MF799 ST Applications * * * * * * * Ethernet 10 or 100Mbps Token Ring Fibre Channel 266Mbps FDDI ATM-SDH/SONET 155Mbps Intra-Office Telecom WDM Applications (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. 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 62.5/125m fiber. Features ST Assembly * Full Duplex Communication Over One Fiber * Dual Wavelengths 820/1300nm * Very Small Size * Very Low Internal Crosstalk * Packaged in IndustryStandard ST(R) Receptacle * Designed for 62.5/125m Fiber Ordering Information PART # RECEPTACLE MF799 ST -40C to +85C Description Used in combination with the MF699, the MF-799 Duplex Device is designed for WDM MF799 Functional Diagram BOTTOM VIEW BOTTOM VIEW ANODE CATHODE ANODE PIN 1320nm 820nm PIN MF799 ANODE CASE FIBER MF699 1320nm CASE CATHODE LED 820nm LED ANODE CATHODE BOTTOM VIEW DICHROIC BEAMSPLITTER BOTTOM VIEW 13329.11 1997-04-01 28 Datacom, Video Link, Intra-Office Telecom, WDM Duplex Device Absolute Maximum Ratings* Parameter Storage Temperature Operating Temperature (Fig 2) LED Power Dissipation (Fig 2) LED Continuous Forward Current (f10kHz) LED Peak Forward Current (Duty cycle 50%, f1MHz) LED Reverse Voltage PIN Reverse Voltage Solder Temperature (Note 1) Symbol Tstg Top Ptot IF IFRM VRL VRP Tsld Min.
