HFBR-11T Transmitter HFBR-1T Receiver 100 nm Fiber Optic Transmitter and Receiver Data Sheet Description The HFBR-000 Series is designed to provide the most cost-effective 100 nm fiber optic links for a wide variety of data communication applica tions from low-speed distance extenders up to SONET OC- signal rates. Pinouts identical to Avago HFBR-0400 Series allow designers to easily upgrade their 80 nm links for farther distance. The transmit ter and receiver are compatible with two popular optical fiber sizes: 50/15 m and.5/15 m diameter. This allows flexibility in choosing a fiber size. The 100 nm wave length is in the lower dispersion and attenua tion region of fiber, and provides longer distance capabilities than 80 nm LED technology. Typi cal distance capabilities are km at 15 MBd and 5 km at MBd. Transmitter The HFBR-11T fiber optic transmitter contains a 100 nm InGaAsP light emitting diode capable of efficiently launching optical power into 50/15 μm and.5/15 m diameter fiber. Converting the interface circuit from a HFBR-14XX 80 nm transmitter to the HFBR-11T requires only the removal of a few passive components. Features Low cost fiber optic link Signal rates over 155 megabaud 100 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.5/15 m and 50/15 m fiber Compatible with HFBR-0400Z Series Receiver also specified for SM cable spec (9/15 m) Applications Desktop links for high speed LANs Distance extension links Telecom switch systems TAXlchip compatible Receiver The HFBR-1T receiver con tains an InGaAs PIN photodiode and a low-noise transimpedance preamplifier that operate in the 100 nm wavelength region. The HFBR- 1T 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 15 MHz. Low-cost external compo nents can be used to convert the analog output to logic compatible signal levels for a variety of data formats and data rates. The HFBR-1T is pin compatible with HFBR-4X receivers and can be used to extend the distance of an existing application by substituting the HFBR-1T for the HFBR-41. *ST is a registered trademark of AT&T Lightguide Cable Connectors

Package Information HFBR-000 Series transmitters and receivers are housed is a dual-in-line package made of high strength, heat resistant, chem ically resistant, and UL V-0 flame retardant plastic. Transmitters are identified by the brown port color; receivers have black ports. The package is autoinsertable and wave solderable for high volume production applications. 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 com pressed air is often sufficient to remove particles of dirt; methanol on a cotton swab also works well..81 (0.150).54 (0.100) /8- UNEF-A.

Typical data are at T A = 5 C.. Thermal resistance is measured with the transmitter coupled to a connector assembly and mounted on a printed circuit board; JC < JA.. 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 (MILSTD-85/1), which approximates a standard test connector. Average power measurements are made at 1.5 MHz with a 50% duty cycle drive current of 0 to I F,peak ; I F,average = I F,peak /. Peak optical power is db higher than average optical power. 4. When changing from W to dbm, the optical power is referenced to 1 mw (1000 W). Optical power P(dBm) = 10*log[P( W)/1000 W]. 5. Fiber NA is measured at the end of 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.. 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.. Optical rise and fall times are measured from 10% to 90% with.5/15 m fiber.

Notes: 1..0 mm from where leads enter case.. The signal output is referred to V CC, and does not reject noise from the V CC power supply. Consequently, the V CC power supply must be filtered. The recommended power supply is +5 V on V CC for typical usage with +5 V ECL logic. A -5 V power supply on V EE is used for test purposes to minimize power supply noise.. Typical specifications are for operation at T A = 5 C and V CC = +5 V DC. 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-Circuits TM, BLP-100*] with - db bandwidth of 100 MHz.. -11.0 dbm is the maximum peak input optical power for which pulse-width distortion is less than 1 ns.. Electrical bandwidth is the frequency where the responsivity is - 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.0 ns rise and fall time (such as the HFBR-11T) will be approximately 0. ns longer than the specifled rise and fall times. E.g.: measured t r,f [(specifled t r,f ) + (test source optical t r,f ) ] 1/. 9. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform. 10. Percent overshoot is defined as: ((V PK - V 100% )/V 100% ) x 100%. The overshoot is typically % with an input optical rise time 1.5 ns. 11. The bandwidth*risetime product is typically 0.41 because the HFBR-1TZ has a second-order bandwidth limiting characteristic.
