AFBR-S10TR001Z block diagram Transmitter Package The transmitter contains a 650nm LED which can be directly driven by a current. The LED is packaged in an optical subassembly, part of the transmitter section. The optical subassembly couples the output optical power efficiently into POF fiber. The transceiver package consists of the opto-electrical subassembly and the housing as illustrated in the block diagrams in Figure 1. The package outline drawing and pin-outs are shown in Figures 2 and 3. The opto-electrical subassembly utilizes a high volume assembly process together with low cost lens elements which result in a cost effective building block. It consists of the active LED and the receiver IC with integrated photodiode. Receiver The receiver utilizes an ASIC with integrated photodiode and a linear transimpedance amplifier (TIA). It is packaged in an optical sub-assembly, part of the receiver section. This optical subassembly couples the optical power efficiently from POF fiber to the receiving photodiode. The output voltage is proportional to the coupled input optical power. There are 8 signal pins, 4 EMI shield solder posts and 2 mounting posts, which exit the bottom of the housing. The solder posts are isolated from the internal circuit of the transceiver and are to be connected to chassis ground. The mounting posts are to provide mechanical strength to hold the transceiver to the application board. 2.54 (6×) 2.54 3.23 4.23 0 21.45 R0 15.9 .5( 4× ) 6.35 5.75 7.65 3.68 2.68 0 0.63 1.5 1.9 3.4 TX (0.3) 6.65 12.6 11.9 Optical Axes 2.67 3 RX 7.35 [2] Figure 2.

Limits apply to each parameter in isolation, all other parameters having values within the recommended operation conditions. It should not be assumed that limiting values of more than one parameter can be applied to the products at the same time. Exposure to the absolute maximum ratings for extended periods can adversely affect device reliability. Parameter Symbol Min. Max.
