The power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module Rx Vcc and Tx Vcc. A GND plane under the module is required for good EMI and sensitivity performance.

NO METAL TRACES OR GROUND CONNECTION IIN KEEP-OUT AREAS. 3.HOLES FOR HOUSING LEADS MUST BE TIED TO SIGNAL GROUND. Printed Circuit Board Layout Considerations A fiber-optic receiver employs a very high gain, wide bandwidth transimpedance amplifier. This amplifier detects and amplifies signals that are only tens of nA in amplitude when the receiver is operating near its limit. Any unwanted signal currents that couple into the receiver circuitry causes a decrease in the receiver’s sensitivity and can also degrades the of the receiver’s signal detect (SD) circuit. To minimize the coupling of unwanted noise into the receiver, careful attention must be given to the printed circuit board. UNIVERSE PHOTONICS CO., LTD.

In applications that include many other high speed devices, a multi-layer PCB is highly recommended. This permits the placement of power and ground on separate layers, which all them to be isolated from the signal lines. Multilayer construction also permits the routing of signal traces away from high level, high speed signal lines. To minimize the possibility of coupling noise into the receiver section, high level, high speed signals such as transmitter inputs and clock lines should be routed as far away as possible from the receiver pins. Noise that couples into the receiver through the power supply pins can also degrade performance. It is recommended that a pi filter is designed in both the transmitter and receiver power supplies. EMI and ESD Considerations Transceivers offer a metal case and shielded design to minimize the EMI challenge facing the host equipment designer. These transceivers provided superior EMI performance. This greatly assists the designer in the management of the overall system EMI performance. LASER Safety This single mode transceiver is a Class1 laser product. It complies with IEC 825 and FDA 21 CFR1040.10 and 1040.11.The transceiver must be operated within the specified temperature and voltage limits. The optical ports of the module shall be terminated with an optical connector or with a dust plug. UNIVERSE PHOTONICS CO., LTD.
