The laser OSA is driven by a LD driver IC which converts differential input LVPECL logic signals into an analog laser driving current. Receiver Section The receiver utilizes an InGaAs PIN photodiode mounted together with a trans-impedance preamplifier IC in an OSA. This OSA is connected to a circuit providing post-amplification quantization, and optical signal detection. Receiver Signal Detect Signal Detect is a basic fiber failure indicator. This is a single-ended LVPECL output. As the input optical power is decreased, Signal Detect will switch from high to low (deassert point) somewhere between sensitivity and the no light input level. As the input optical power is increased from very low levels, Signal Detect will switch back from low to high (assert point). The assert level will be at least 1.0 dB higher than the deassert level. http:// www.ritekom.com Version 3.3 Headquarters : No. 669, Sec. 4 Chung Hsing Road Chudung, HsinChu, Taiwan 310, ROC Tel: +886-3-582-8270 Fax: +886-3-582-8416 4/10 Date: 2003/02/17 1310 nm Single-mode Transceiver (S1.1) 1x9, SC Duplex Connector, 3.3 V 155 Mbps ATM/SONET OC-3/SDH STM-1 Typical BER Performance of Receiver versus Input Optical Power Level 1.E-04 1.E-05 1.E-06 BER 1.E-07 1.E-08 1.E-09 1.E-10 1.E-11 1.E-12 -2.5 -2 -1.5 -1 -0.5 0 0.5 Relative Input Optical Power (dB) The figure shows the relationship between typical trade-off of BER and Relative Input Optical Power.

When designing the circuit interface, there are a few fundamental guidelines to follow. (1) The differential data lines should be treated as 50 Ω Micro strip or strip line transmission lines. This will help to minimize the parasitic inductance and capacitance effects. Locate termination at the received signal end of the transmission line. The length of these lines should be kept short and of equal length. (2) For the high speed signal lines, differential signals should be used, not single-ended signals, and these differential signals need to be loaded symmetrically to prevent unbalanced currents which will cause distortion in the signal. (3) Multi layer plane PCB is best for distribution of VCC, returning ground currents, forming transmission lines and shielding, Also, it is important to suppress noise from influencing the fiber-optic transceiver performance, especially the receiver circuit. (4) A separate proper power supply filter circuits shown in Figure for the transmitter and receiver sections. These filter circuits suppress Vcc noise over a broad frequency range, this prevents receiver sensitivity degradation due to VCC noise. (5) Surface-mount components are recommended. Use ceramic bypass capacitors for the 0.1 µF capacitors and a surface-mount coil inductor for 1 µH inductor. Ferrite beads can be used to replace the coil inductors when using quieter VCC supplies, but a coil inductor is recommended over a ferrite bead. All power supply components need to be placed physically next to the VCC pins of the receiver and transmitter. (6) Use a good, uniform ground plane with a minimum number of holes to provide a low-inductance ground current return for the power supply currents. http:// www.ritekom.com Version 3.3 Headquarters : No. 669, Sec. 4 Chung Hsing Road Chudung, HsinChu, Taiwan 310, ROC Tel: +886-3-582-8270 Fax: +886-3-582-8416 7/10 Date: 2003/02/17 1310 nm Single-mode Transceiver (S1.1) 1x9, SC Duplex Connector, 3.3 V 155 Mbps ATM/SONET OC-3/SDH STM-1 Recommended Board Layout Hole Pattern Unit : mm(inches) This transceiver is compatible with industry standard wave or hand solder processes.
