What are the main applications of SFP+ CWDM and SFP+ DWDM in 10G optical modules?

The 10GSFP+CWDM optical module is a coarse wavelength division multiplexed optical module that is usually used with single mode fiber.
This optical module saves fiber resources by using CWDM technology, which can significantly improve the flexibility, economy, and reliability of the networking. The power consumption of this optical module is very small, which is 12.5% of the 10GSFP+DWDM optical module.

SFP+ is smaller than the previous XFP optical module and looks the same as an SFP optical module.SFP+ only retains the basic electro-optic and photoelectric conversion functions, which reduces the signal control functions of SerDes, CDR, EDC, MAC, etc. in the original XFP design, which simplifies the design of 10G optical modules and reduces power consumption.
It has significant advantages such as high density, low power consumption, and lower system construction cost.

Product application: 10 Gigabit Ethernet, SDH optical transmission network, WDM system engineering; 10G single-fiber bidirectional system engineering, widely used 10 Gigabit Ethernet fiber data and other communication fields, is the mainstream product of 10 Gigabit modules.

10G DWDM SFP+ optical module
The 10GSFP+DWDM optical module is a relatively rare high-speed, high-capacity dense wavelength division multiplexing optical module. Usually used with single-mode fiber, the transmission distance can be up to 80km, suitable for long-distance data transmission.The optical module can meet the requirements of ultra-large capacity and ultra-long-distance transmission to the greatest extent, providing stable protection for multi-service operation and future network upgrade and expansion. It also supports multiple networking modes, and wavelengths can also be used between nodes. Scheduling.It has a capacity of scalable, flexible access service, a variety of advantages of high reliability and high bandwidth utilization.

It is mainly used in the following four aspects:

The first is a ring network topology that can be used for amplifying DWDM networks, Fibre Channel, fixed and reconfigurable OADM, Fast Ethernet, Gigabit Ethernet, and other optical transmission systems.

Secondly, it is in compliance with the 10GBASE-ZR/ZW standard and can be used for 10G fiber optic cable.

Third, DWDM XFP optical modules, DWDM X2 optical modules, and DWDMXENPAK optical modules are commonly used in applications such as 10G Ethernet, 10G Fibre Channel, SONET (Synchronous Optical Network), and SDH (Optical Transmission Equipment).

Finally, DWDM optical modules can also be used for switch-to-switch interfaces, switch backplane applications, and router/server interfaces.

    With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

    1. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

    AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.

    Dense Wavelength Division Multiplexing (DWDM) technology is capable of transmitting data in an optical fiber using bit wavelength parallel transmission or string line transmission using the wavelength of the laser.It is widely used in different fields of communication networks, including long-distance backbone networks, metropolitan area networks (MANs), residential access networks, and local area networks (LANs).The DWDM optical module is the optical module that uses this technology, so the DWDM optical module has high bandwidth and long-distance transmission characteristics.
