  DWDM   and   OTN   are two different technologies in the field of optical communication. DWDM   is an optical transmission technology used to simultaneously transmit multiple wavelengths of optical signals in optical fibers, thereby expanding the transmission capacity of optical fibers, increasing network bandwidth, and supporting long-distance transmission. OTN is a network transmission technology based on DWDM. In addition to optical transmission, it also provides higher-level switching, management, and monitoring functions to achieve reliable, flexible, and efficient optical network transmission.   Function extension: DWDM mainly focuses on the multiplexing and transmission of optical signals, and does not involve signal exchange, management, and monitoring. OTN introduces higher-level functions on the basis of DWDM. OTN technology provides multi-level exchange, management, and monitoring functions by packaging data in a fixed format. It can handle da...

  FIBERWDM   is the original manufacturer of DWDM equipment with over 10 years of experience and a mature team, providing free DWDM transmission solutions to customers.   DWDM network is an optical transmission technology used to simultaneously transmit multiple optical signals of different wavelengths in optical fibers. It achieves high-capacity optical communication by associating each signal with a unique wavelength and merging them into the same optical fiber. DWDM is widely used in industries such as broadcasting, IDC, finance, cloud computing, and massive data where fiber optic resources are scarce. The working process of DWDM is as follows: Transmitting end:  The laser modulates laser photons of different wavelengths into optical signals with signals through a modulator, and then combines multiple optical signals of different wavelengths into one signal stream through a splitter, which is transmitted to the receiving end through an optical fiber. Fiber optic t...

  In today's digital society, high-speed broadband connection has become an indispensable part of people's daily life and work. The broadband PON network transmits the broadband signal to the end user through the optical fiber to realize the high-speed and stable network connection. Traditional PON networks usually use a single- line   single-access structure, that is, a single fiber to connect only one end-user. However, with the wide spread of digital applications, single-line single access has been unable to meet the needs of users. FIBERWDM's   broadband PON single-line dual-access device  can open two broadband services at the same time using a single-core fiber-optic cable, the product pair loss < 1.6 dB , low failure rate, small size, easy installation and strong concealment. Broadband PON single-line dual-access devices usually consist of two main components: optical multiplexer (MUX) and optical splitter (DEMUX) . The optical multiplexer is used to c...
