1300 nm E-LED Transmitter and PIN/Preamp Receiver for Single-Mode Fiber Technical Data HFBR-0305 Series Features Transmitter • Distances up to 14 km at Signal Rates of 20 MBd • Performance Specified with Single-Mode Fiber Cables • Wave Solder and Aqueous Wash Process Compatible • Panel Mount ST Connectors • Pinout Compatible with HFBR-0400 Series Parts The HFBR-1315TM/1315M single-mode fiber-optic transmitter contains a 1300 nm edgeemitting LED (E-LED) capable of efficiently launching optical power into single-mode fiber. Because it is an LED, and not a laser, the drive circuit is simple and compatible with drive circuits for multimode LED transmitters. Applications Receiver • Single-Mode Extensions to Ethernet (10Base-F) Links • Proprietary Links Using Single-Mode Fiber The HFBR-2315T/2315M receiver contains an InGaAs PIN photodiode and a low-noise transimpedance preamplifier operating in the 1300 nm wavelength region. The HFBR2315T/2315M receives an optical signal and converts it to an analog voltage. The buffered output is an emitter-follower, with a frequency response from dc to typically 125 MHz. Description The HFBR-0305 Series is designed to provide the most cost-effective single-mode solution, and is pin-compatible with HFBR-0400 and HFBR-0300 families of 820 and 1300 nm fiber optic links for multi-mode fiber. This allows designers to use a single circuit and board layout for 820 nm multimode fiber links, 1300 nm multimode fiber links, and 1300 nm single-mode fiber links. Upgrading a multimode solution to single-mode fiber is as simple as switching components on a board. Package HFBR-0305 Series transmitters and receivers are housed in a dual-in-line package made of high strength, heat resistant, chemical resistant, and UL V-0 flame retardant plastic. The HFBR1315TM/1315M is a stainless steel, threaded ST port (panel mountable); the HFBR-1315M is a stainless steel, unthreaded ST port. The HFBR-2315T is a black, non-conductive plastic threaded ST port (panel mountable); the HFBR-2315M is a stainless steel, unthreaded ST port.

Normal static precautions should be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by electrostatic discharge (ESD) Solder Processing The HFBR-0305 Series products are compatible with either hand or wave solder processes. When soldering, it is advisable to leave the protective cap on the port to keep the optics clean. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. Clean compressed air is often sufficient to remove particles of dirt; methanol on a cotton swab also works well. Panel Mounting of Threaded ST Package Style Any standard 3/8 - 32 UNEF-2B threaded nut and washer can be used to secure the threaded ST receptacle to the chassis wall, provided the overall thickness of the chassis wall, washer and nut are less than 5.1 mm (0.2 inch). Agilent supplies the HFBR-4411 kit which consists of 100 each, nuts and washers per the figure below. 3/8 - 32 UNEF 2B THREAD 9.53 DIA. (0.375) The HFBR-0305 Series package is compatible with the following chemicals for cleaning and degreasing: - Aqueous Wash - Naptha - Alcohol (methyl, isopropyl, isobutyl) - Aliphatics (hexane, heptane) The following chemicals are not recommended as they will damage the package: Partially halogenated hydrocarbons such as 1,1,1 Trichloroethane, Ketones such as MEK, Acetone, Chloroform, Ethyl Acetate, Methylene Dichloride and N-methylpyroldone.

When preparing the chassis wall for panel mounting, use the mounting template in the figure below. When tightening the nut, torque should not exceed 0.8 N-m (8.0 in-lb). Note that the maximum nut dimension exceeds the width of the port package, so approximately 2 mm of space between device packages is required to allow nuts to be mounted on adjacent ports. 9.80 (0.386) DIA. 8.0 (0.315) Powered by ICminer.com Electronic-Library Service CopyRight 2003 The HFBR-0305 Series package is made with UL V-0 flame retardant plastic material. Electrostatic Discharge (ESD) Static discharges can occur to the exterior of the equipment chassis containing the HFBR-0305 Series parts. To the extent that their connector receptacles are exposed to the outside of the equipment chassis, they may be subject to whatever ESD system level test criteria that the equipment is intended to meet. Radiated Susceptibility 12.70 DIA. (0.50) INTERNAL TOOTH LOCK WASHER Wash Processing Chemical Resistance Flame Resistance Equipment utilizing these products will be subject to EMI fields in some environments. These HFBR-0305 Series products are expected to withstand fields of up to 10 volts per meter, when tested on a circuit card in free space without an equipment chassis, with no measurable effect on their performance.

The signal output is an emitter follower, which does not reject noise from VCC. Consequently, the power supply must be filtered. The recommended supply is +5 V on VCC for typical usage with +5 V ECL logic. A -5 V supply on VEE is used for test purposes to minimize supply noise. 3. Typical specifications are for operation at TA = 25°C, VCC = +5 VDC, VEE = 0 V. 4. The test circuit layout should be in accordance with good high frequency circuit design techniques. 5. Measured with a Mini-Circuits 9-pole “brick wall” low-pass filter, BLP-100, with -3 dB bandwidth of 100 MHz. 6. -14 dBm is the maximum peak input optical power from single-mode fiber for which pulse-width distortion is less than 1 ns. 7. Electrical bandwidth is the frequency where the responsivity is -3 dB (electrical) below the responsivity measured at 50 MHz. 8. The bandwidth * risetime product is typically 0.41 because the HFBR2315T/2315M has a second-order bandwidth limiting characteristic. 9. The specified rise and fall times are referenced to a fast square wave optical source. Rise and fall times measured using an LED optical source with a 2.0 ns rise and fall time (such as the HFBR-1315TM/1315M) will be approximately 0.6 ns longer than the specified rise and fall times. E.g.: measured tr,f ≅ [(specified t r,f) 2 + (test source optical tr,f )2]1/2 10. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform. 11. Percent overshoot is defined as: ((VPK - V100%)/V100%) x 100%. The overshoot is typically 2% with an input optical rise time < 1.5 ns.
