Optoelectronic Transceiver Modules Alumina Ceramic Substrate
The aluminum oxide ceramic substrate for optoelectronic transceiver modules is a really important part. It plays a very important role in making modern optical-electrical communication systems work efficiently. It acts as a dependable base for putting together different optoelectronic components. This allows signals to be transmitted and received smoothly.
1. Material Properties
(1) High - Purity Alumina Content
Typically, these substrates are composed of high - purity aluminum oxide (Al₂O₃), often with a purity level of 96% or higher. The high - purity alumina provides excellent electrical insulation properties. With a volume resistivity usually exceeding 10¹⁴ Ω·cm, it effectively prevents electrical leakage and crosstalk between different electrical paths on the substrate. This is of utmost importance in optoelectronic transceiver modules where multiple high - speed electric…
