HFBR-1312TZ Transmitter HFBR-2316TZ Receiver 1300 nm Fiber Optic Transmitter and Receiver Data Sheet Description Features The HFBR-1312TZ Transmitter and HFBR-2316TZ Receiver are designed to provide the most cost-effective 1300 nm fiber optic links for a wide variety of data communication applications from low-speed distance extenders up to SONET OC-3 signal rates. Pinouts identical to Avago HFBR0400Z Series allow designers to easily upgrade their 820 nm links for farther distance. The transmitter and receiver are compatible with two popular optical fiber sizes: 50/125 µm and 62.5/125 µm diameter. This allows flexibility in choosing a fiber size. The 1300 nm wavelength is in the lower dispersion and attenuation region of fiber, and provides longer distance capabilities than 820 nm LED technology. Typical distance capabilities are 2 km at 125 MBd and 5 km at 32 MBd. • RoHS-compliant Transmitter Applications The HFBR-1312TZ fiber optic transmitter contains a 1300 nm InGaAsP light emitting diode capable of efficiently launching optical power into 50/125 µm and 62.5/125 µm diameter fiber. Converting the interface circuit from a HFBR-14XXZ 820 nm transmitter to the HFBR-1312TZ requires only the removal of a few passive components. • Desktop links for high speed LANs *ST is a registered trademark of AT&T Lightguide Cable Connectors • Low cost fiber optic link • Signal rates over 155 megabaud • 1300 nm wavelength • Link distances over 5 km • Dual-in-line package panel-mountable ST* and SC connector receptacles • Auto-insertable and wave-solderable • Specified with 62.5/125 µm and 50/125 µm fiber • Compatible with HFBR-0400Z Series • Receiver also specified for SM cable spec (9/125 µm) • Distance extension links • Telecom switch systems • TAXlchip compatible HFBR-2316TZ Receiver 6 2, 6 ANODE 2 3 CATHODE BOTTOM VIEW Mechanical Dimensions 3, 7 4 5 4 5 3 6 3 6 2 7 2 7 1 8 1 8 PIN NO. 1 INDICATOR PIN 1 2 3 4 5 6 7* 8 BOTTOM VIEW FUNCTION N.C.

The HFBR2316TZ receives an optical signal and converts it to an analog voltage. The buffered output is an emitter-follower, with frequency response from DC to typically 125 MHz. Low-cost external components can be used to convert the analog output to logic compatible signal levels for a variety of data formats and data rates. The HFBR-2316TZ is pin compatible with HFBR-24X6Z receivers and can be used to extend the distance of an existing application by substi-tuting the HFBR-2316TZ for the HFBR-2416Z. The transmitter and receiver are housed in a dual-in-line package made of high strength, heat resistant, chem ically resistant, and UL V‑0 flame retardant plastic. The package is auto-insertable and wave solderable for high volume production applications. 2 Note: The “T” in the product numbers indicates a Threaded ST connector (panel mountable), for both transmitter and receiver. Handling and Design Information When soldering, it is advisable to leave the protective cap on the unit 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. DIA. Panel Mounting Hardware Recommended Chemicals for Cleaning/Degreasing The HFBR-4411Z kit consists of 100 nuts and 100 washers with dimensions as shown in Figure 1. These kits are available from Avago or any authorized distributor. Any standard size nut and washer will work, provided the total thickness of the wall, nut, and washer does not exceed 0.2 inch (5.1 mm). Alcohols (methyl, isopropyl, isobutyl) Aliphatics (hexane, heptane) Other (soap solution, naphtha) When preparing the chassis wall for panel mounting, use the mounting template in Figure 2. When tightening the nut, torque should not exceed 0.8 N-m (8.0 in-lb). Do not use partially halogenated hydrocarbons (such as 1.1.1 trichloroethane), ketones (such as MEK), acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or N-methylpyrolldone. Also, Avago does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. 3/8 - 32 UNEF 2B THREAD 9.53 DIA. (0.375) 12.70 DIA.

Typical data are at TA = 25°C. 2. Thermal resistance is measured with the transmitter coupled to a connector assembly and mounted on a printed circuit board; ΘJC < ΘJA. 3. Optical power is measured with a large area detector at the end of 1 meter of mode stripped cable, with an ST* precision ceramic ferrule (MIL-STD-83522/13), which approximates a standard test connector. Average power measurements are made at 12.5 MHz with a 50% duty cycle drive current of 0 to IF,peak; IF,average = IF,peak/2. Peak optical power is 3 dB higher than average optical power. 4. When changing from µW to dBm, the optical power is referenced to 1 mW (1000 µW). Optical power P(dBm) = 10*log[P(µW)/1000µW]. 5. Fiber NA is measured at the end of 2 meters of mode stripped fiber using the far-field pattern. NA is defined as the sine of the half angle, determined at 5% of the peak intensity point. When using other manufacturer’s fiber cable, results will vary due to differing NA values and test methods. 6. Overshoot is measured as a percentage of the peak amplitude of the optical waveform to the 100% amplitude level. The 100% amplitude level is determined at the end of a 40 ns pulse, 50% duty cycle. This will ensure that ringing and other noise sources have been eliminated. 7. Optical rise and fall times are measured from 10% to 90% with 62.5/125 µm fiber.

The signal output is referred to VCC, and does not reject noise from the VCC power supply. Consequently, the VCC power supply must be filtered. The recommended power supply is +5 V on VCC for typical usage with +5 V ECL logic. A -5 V power supply on VEE is used for test purposes to minimize power supply noise. 3. Typical specifications are for operation at TA = 25°C and VCC = +5 VDC. 4. The test circuit layout should be in accordance with good high frequency circuit design techniques. 5. Measured with a 9-pole “brick wall” low-pass filter [Mini-CircuitsTM, BLP-100*] with -3 dB bandwidth of 100 MHz. 6. -11.0 dBm is the maximum peak input optical power 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 specifled 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-1312TZ) will be approximately 0.6 ns longer than the specifled rise and fall times. E.g.: measured tr,f ~ [(specifled tr,f )2 + (test source optical tr,f )2]1/2. 9. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform. 10. Percent overshoot is defined as: ((VPK - V100%)/V100%) x 100% . The overshoot is typically 2% with an input optical rise time ≤1.5 ns. 11. The bandwidth*risetime product is typically 0.41 because the HFBR-2316TZ has a second-order bandwidth limiting characteristic.
