AFBR-59F1Z 125MBd Compact 650 nm Transceiver for Data Communication over Polymer Optical Fiber (POF) cables with a bare fiber locking system Data Sheet Description Features The Avago Technologies AFBR-59F1Z transceiver provides Easy bare fiber termination solution for 2.2mm jacket system designers with the ability to implement Fast POF Ethernet (100Mbps) communication over 2.2 mm jacketed EMI/ EMC robust standard Polymer Optical Fiber (POF). Link lengths: The innovative bare fiber locking mechanism of the up to 40 m POF (NA = 0.5) or 60 m POF (NA = 0.3). transceiver allows connection of POF cable with a simple Compatible with IEEE 802.3u Fast Ethernet data insert and lock system eliminating the need for connectors. communications standard This facilitates fast installation and maintenance. LVPECL interface compatible The AFBR-59F1Z is Laser Class 1, lead-free and compliant Operating temp. range -40 C to 85 C with RoHS. The very compact design is similar to that of the well known RJ-45 connector. 3.3 V power supply operation Integrated optics to efficiently focus light for fiber Transmitter coupling The transmitter consists of a 650nm LED which is Electrically compatible with 100BaseFX PHY ICs controlled by a fully integrated driver IC. The LED driver operates at 3.3V. It receives Low Voltage Positive Emitter Applications Coupled Logic (LVPECL) or Low Voltage Differential Factory automation Signaling (LVDS) differential electrical input and converts Power generation and distribution system it into a modulated current driving the LED. The LED and driver IC are packaged in an optical subassembly. Industrial vision system The optimized lens system of the optical subassembly Solar panel tracking system couples the emitted optical power very efficiently into Home/Office Networking 1mm core POF cable. Receiver Package The receiver utilizes a fully integrated single chip solution which provides excellent immunity to EMI and fast The transceiver package contains the two optical transient dV/dt rejection. The receiver directly converts subassemblies, which are mounted in the housing for light to a differential LVPECL output signal and operates bare fiber connection. at 3.3V. The integrated receiver is packaged in an optical The metal shield on the bare fiber clamp transceiver subassembly which couples optical power efficiently from provides excellent immunity to EMI/EMC POF to the receiving PIN. The receiver features a signal detect (SD) output. The SD output voltage level is LVPECL.0.8 (10 ) 1.3 (2 ) Pin description and recommended PCB footprint AFBR-597F1Z has ten active signal pins (including supply voltage and ground pins), two EMI shield solder posts, two additional ground pins, and two mounting posts. The EMI shield solder posts and additional ground pins are isolated from the transceiver internal circuit and should be connected to the equipment chassis ground or signal ground. Connecting the two additional ground pins to ground provides EMI shielding to the front of the device. Grounding these pins will also provide a ground connection of the POF jacket in order to ground small leakage currents in high voltage applications such as in HVDC installations. The mounting posts provide additional mechanical strength to hold the transceiver module on the application board. Figure 1 shows the top view of the PCB footprint and pin-out diagram.
