WDM Optical Module
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over a single strand of fiber (also called wavelength-division duplexing) as well as multiplication of capacity. The.

Extinction ratio of optical communication module
ER (Extinction Ratio) is the ratio of the average optical power when the optical module transmits a logic "1" to the average optical power when it transmits a logic "0". Generally expressed in logarithms, ER is a constant for a linear attenuation system. For a graphical description, the eye-diagram is commonly. The Extinction Ratio defines how distinct the “on” (logic 1) and “off” (logic 0) states of an optical transmitter are, making it a direct indicator of signal quality in optical transceivers. As design/test margins get tighter, the challenges of making accurate and repeatable extinction ratio measurements become more apparent.
