2019-09-11
With the development of data center with broadband upgrade, optical module plays more and more important role. We know that light modules have evolved over the years,The speed was increased from 10G to 200G, and the packaging was improved from 1X9 packaging optical module to the current mainstream QSFO28 optical module packaging, each time the development. The SFP28 optical module is one of the family of optical modules. The appearance of 25G optical module makes up for the high price of high speed optical module and the high speed of 10G optical module cannot meet the needs of users to some extent, so it is a low speed optical module in the optical module market. The 25G SFP28 optical module is an optical module with a transmission rate of 25Gbps. It is a new Ethernet standard with many advantages, mainly used for the interconnection of data center servers and switches. The biggest advantage of 25G Ethernet technology is its ability to maximize bandwidth and port density. It can deliver 100 Gb of data using 25Gb/s single channel physical layer technology, providing the most energy efficient way to meet the growing demands of next-generation data center networks.
The 25G SFP28 LR 1310nm 10km optical module is a hot-swabbed, single-channel, high-performance module for short-range data. It has a transmission distance of up to 10 kilometers and supports communication and interconnection applications. The optical interface of this module adopts double LC socket, which is mainly used for the operation of single-mode optical fiber system with nominal wavelength of 1310nm. Because the best I/O performance and fiber capacity of the 25G SFP28 optical module is 2.5 times that of 10G Ethernet and has higher port density, it can also save operating costs by reducing the number of To R switches and cables. The 25G SFP28 optical module also has less loss than the 100G optical module. In addition, the 25G SFP28 optical module can achieve a transmission rate of 50G using 2 optical channels, making it a better choice than the 40G optical module using 4 10G optical channels. The introduction of optical fiber to households greatly meets the needs of users on the network. Optical module is an optical communication network to realize photoelectric conversion. The sending end converts electrical signals into optical signals. When choosing optical modules, it's not as if the more expensive or the bigger the capacity is the best. The 25G SFP28 LR is popular because it doesn't cost as much or consume as a 40G/100G optical module, and the 10G optical module can't meet the network needs of current users. 25G is an optical module with a transmission rate of 25Gbps, hot-swabbed SFP28 package, central wavelength of 1310nm, and the transmission distance of single-mode fiber can reach 10Km when used. Support DDM digital diagnosis function, which can monitor the working temperature, working voltage, working current, emitting light power and receiving light power of the module in real time. Optical interface adopts double LC socket, high port density; The 25G SFP28 LR optical module adopts DFB laser and PIN photo detector, LC duplex interface, CDR is built in transmitter and receiver, which is mainly used in 25G Ethernet. Different center wavelengths and lasers result in different fiber hops and transmission distances.25G multi-mode optical module is mainly used with OM3OM4 multi-mode optical fiber, the maximum transmission distance is 100m, which is suitable for short distance data transmission; The 25G single-mode optical module is mainly used with single-mode optical fiber, and the maximum transmission distance can reach 10km, which is suitable for long-distance data transmission. The data transmission technology of 25G optical module can not only improve the network performance of the data center, but also effectively reduce the number of overhead switches deployed in the data center, which can fully meet the high rate and high density requirements of the data center for network deployment. Moreover, in the case that 10G optical module cannot meet the rate requirements of most data centers, the price and power consumption of 40G optical module and 100G optical module are too high, while 25G optical module can exactly meet the requirements of low power consumption and low cost of data center.
Like the 25G optical module, the 25G high-speed cable can be directly connected with the 25G Ethernet switch to realize the network deployment of 25G Ethernet. Compared with the 25G optical module, the 25G high-speed cable is more suitable for the short distance direct connection between the data center racks, and the length is generally 1~7 meters. The 25G DAC high-speed cable consists of a passive copper core cable and two sfp28-sfp28 optical fiber transceiver modules, which look like optical modules but have no laser installed inside.25G DAC high-speed cable can replace 25G optical module to realize short distance data transmission, which is an effective cost-effective solution for the short distance application of 25G switch in data center. Moreover, the price of 25G DAC high-speed cable has advantages over that of 25G optical module, mainly because the DAC high-speed cable has no laser installed, so the price is cheaper than that of optical module.

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.
