Drawing:
10G TOSA DWDM:
The 1550nm band is the primary band for DWDM (Dense Wavelength Division Multiplexing), and multiple TOSAs can be used to build multi-channel, high-capacity transmission systems.
TOSA is a laser transmission component that converts electrical signals into optical signals. Optical power and threshold are the key to performance judgment. It is mainly composed of semiconductor laser diodes, adapters and mold sleeves.
The TOSA is designed to meet the specified fiber launch conditions for both multimode and single mode fiber options. Excellent optical performance is achieved by matching the electrical characteristics of the TOSA and laser with the external circuitry. Independent differential laser bias and modulation pins significantly reduce the electrical power required at the module level and help reduce overall electromagnetic emissions.The TOSA is designed to meet the specified fiber launch conditions for both multimode and single mode fiber options.
