Optical Transmission
WDM Optical Multiplexer

Each of the 4 / 8 optical channels are physically multiplexed into a single FIBER on the transmit side. Similarly, each of the 4 / 8 receive channels are multiplexed into a single FIBER on the receive side. 4 / 8 distinctly separate optical channels are transmitted / received on a single optical fiber pair. It is equivalent to using 4 / 8 separate optical fiber pairs instead of a single optical fiber pair to transmit / receive the 4 / 8 x optical channels. This is made possible by using WDM technology that use specific wavelengths in the WDM band to physically transmit and receive 4 / 8 channels on a single fiber pair instead of using white lasers that would only have the capability to transmit one single optical channel of each fiber.

The VCL-9025 WDM Optical Multiplexer ensures complete security and reliability through physical separation, because each of the 4 / 8 optical channels are transmitted completely independently of each other – even though they are being transmitted on a single optical fiber pair.

VCL-9025 WDM Optical Multiplexer using WDM technology in optical fiber communication systems significantly increases the capacity of the network. This helps in increased bandwidth capacity of the fiber, allowing for the transmission of more data and supporting higher data rates.
