We have achieved bidirectional communication using a single-core optical fiber.
In the ROF system, the transmission and reception of light in a one-to-one configuration uses two separate optical fibers for upstream and downstream, respectively, in a dual-core multiplexing method. However, in systems that use dark fiber, the impact of management costs on operational expenses cannot be ignored, making it difficult to easily increase the number of fibers. By preparing and combining laser diodes of different optical wavelengths, it is possible to multiplex multiple optical signals onto a single optical fiber. The ROF-Link WDM Module has achieved bidirectional communication using a single optical fiber by combining ROF-Links of different wavelengths with WDM filters. We also have a track record of providing necessary peripheral devices tailored to your system requirements, so please consult with our sales team. 【Features】 ○ Wireless transmission bandwidth of 60MHz to 1GHz (ROF201) and 60MHz to 3GHz (ROF202) ○ Transmission of two wavelengths over a single optical fiber using two E/O devices of different wavelengths ○ Wireless signal input to each E/O can be transmitted at the same frequency ○ When using existing optical cables, bidirectional transmission via optical multiplexing is possible without increasing the number of fibers For more details, please contact us or download the catalog.
