| Fiber Optic LAN Components Connectorized PIN Plus Preamplifier FEATURES * Prealigned SC Connector sleeve * Data rates from 622 Mbps to 2.5 Gbps * PIN detector and preamplifier in a TO-46 heremtic package * 3.3V operation * GaAs PIN detector and BiCMOS preamplifier * Differential Output for low noise * 2.4 GHz typical Bandwidth HFD3381-102 The HFD3381-102 is a high-performance 850nm GaAs detector and preamplifier packaged for high-speed data communications. The product is designed for ease of use by the module designer or manufacturer for data rates from 622 Mbps to 2.5 Gbps. The HFD3381-102 converts optical power into an electrical signal that is used in fiber optic communications and other applications. As the light increases, the output voltage increases, limiting at input powers above -10dBm. The differential output is designed to be AC coupled into a data amplifier. The pre-aligned and lensed package with an industry standard SC style connector sleeve, allows for "drop in" assembly to reduce manufacturing cost. The Honeywell HFD3381-102 is designed to interface with 50/125 and 62.5/125mm multimode fiber.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operations section for extended periods of time may affect reliability. ELECTRO-OPTICAL CHARACTERISTICS (Vcc=3.3V, AC coupled to 50, 0C 6 7 8 760 850 Notes: 1. 2. 3. Pin refers to the total optical power at the face of the fiber optic cable input to the HFD3381-102. Responsivity measured with source wavelength of 850nm, 125MHz square wave, Pin=20W peak, Rload=50. The output voltage increases as received light power increases, up to approximately -15dBm. The preamplifier is designed to limit the electrical output signal above this optical input level, and does not introduce signal distortion until the average input power exceeds 0dBm. Bandwidth is measured with a small signal sinusoidal light source with 50 W average power, Rload=50. RMS input referred optical noise is obtained by measuring the RMS output referred noise, then dividing by the responsivity. PSRR is measured from 300KHz to 1GHz by injecting a - 20dB electrical signal on the Vcc pin. The nominal value at 100MHz is recorded. No external bypass components are assumed. An external Vcc filter network will greatly increase the PSRR. Measured at the 50% level of output pulses using 0.5 GHz square wave with <200 ps rise time. Rise and fall times are measured with source wavelength of 850nm, 125MHz square wave, with optical rise and fall times < 200ps, Pin=20W peak, Rload=50. 4. 5. NOTICE The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD). To prevent ESDinduced damage and/or degradation to equipment, take normal ESD precautions when handling this product 6. 2 Honeywell * For application help: call 1-800-537-6945 Fiber Optic LAN Components Connectorized PIN Plus Preamplifier FIGURE 1: INTERNAL SCHEMATIC DIAGRAM OF THE HFD3381-102 Vcc HFD3381-102 Inverted Output Non-Inverted Preamplifier PIN Internal Limiting Amplifier Ground FIGURE 2: RECOMMENDED INTERFACE CIRCUIT FOR THE HFD3381-102 HFD3381 R Vcc C1 Ground Inverted Output 50 ohm transmission line Non-Inverted Output 50 ohm transmission line C2 C2 Limiting Amplifier or Test Equipment Input Input R=10= C1 = 10 nF C2 = Data rate dependant (22nF for rates > 1Gbps For application help: call 1-800-537-6945 Honeywell * 3 Fiber Optic LAN Components Connectorized PIN Plus Preamplifier ORDER GUIDE Catalog Listing HFD3381-102 Description Connectorized PIN Plus Preamplifier HFD3381-102 SALES AND SERVICE Honeywell Sensing and Control serves its customers through a worldwide network of sales offices and distributors.
