In long-distance transmission, optical fiber resources are very tight. Every additional optical fiber represents an increase in cost. Saving optical fiber resources is very important in long-distance transmission. If there are many services, wavelength division multiplexing will be used. However, if there are few services, wavelength division multiplexing is not suitable and the cost is very high. In order to solve the problem of long-distance transmission of a small number of services, YXFiber has launched a 100G BIDI 80KM optical module, which can meet the 100G transmission link of up to 80KM. Let's take a closer look at it in this article.
YXFiber's 100G BIDI 80KM optical module is designed for 80KM long-distance transmission. It is packaged in QSFP28 and has a simplex LC interface. During transmission, the built-in WDM MUX of the module separates the transmitted optical signal and the received optical signal without interfering with each other. It can realize the simultaneous sending and receiving of data on one optical fiber. Only one optical fiber is needed to establish a 100G rate link, saving the use of long-distance optical fiber and reducing the laying cost of long-distance optical fiber.
The 100G BIDI 80KM optical module has 4 electrical channels, each with a rate of 25.78Gb/s, supporting a total rate of 103.125Gb/s. With the support of FEC, it can achieve a transmission distance of up to 80km, which can meet the needs of various long-distance high-speed transmission scenarios such as data center interconnection and metropolitan area network transmission.
The receiver uses SOA PIN, SOA is a semiconductor optical amplifier, which can amplify the optical signal at the receivi
ng end and improve the receiving sensitivity of the signal, thereby extending the transmission distance and ensuring the quality of the signal after long-distance transmission. The laser uses LWDM EML, LWDM is a local wavelength division multiplexing technology, and EML is an electro-absorption modulated laser. The combination of the two can achieve efficient and stable optical signal transmission, and the central wavelength range is 1280nm to 1304nm, ensuring the accuracy and stability of signal transmission.
The maximum power consumption is only 6.5W, which can effectively reduce energy consumption, reduce the power supply pressure and heat dissipation pressure of the equipment room. At the same time, the mature hardware solution brings strong reliability, providing a strong guarantee for the long-term reliable operation of the network.
At the transmitting end, the 25G data of four electrical channels are transmitted to four laser drivers, which control four LAN-WDM lasers with central wavelengths of 1273.54nm, 1277.89nm, 1282.26nm, and 1286.66nm (the other end is 1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm), and then the four 25G optical signals are multiplexed into one 100G optical signal through the built-in WDM MUX, and transmitted to a single-mode optical fiber through the simplex LC interface to complete the conversion of electrical signals to optical signals.
At the receiving end, the weak optical signal received by the optical module is amplified by the SOA and amplified to an intensity that can be recognized by the PIN receiver. Then, after demultiplexing by the built-in WDM MUX of the module, the received 100G optical signal is decomposed into four 25G optical signals, which are restored by the PIN receiver and the transimpedance amplifier, retimed and transmitted to the output driver, thereby completing the conversion of optical signals to electrical signals.
