25G SFP28

25G SFP28 optical module is the transmission rate is 25Gbps module, the appearance of 25G optical module to a certain extent to make up for the high rate of light module price is too high, excessive power consumption, and 10G optical module rate cannot meet the user’s needs defects. The 25G SFP28 optical module, primarily used for the interconnection of data center servers and switches, is a new Ethernet standard with multiple advantages, introduced by the IEEE 802.3 Working Group in July 2014 and completed its revision in June 2016. The greatest advantage of 25G Ethernet technology for data centers is the ability to maximize bandwidth and port density, and its ability to achieve 100Gb of data transfer using 25Gb/s single-channel physical layer technology, and it provides the most energy-efficient way to meet the growing needs of next-generation data center networks.

25G SFP28 Benefit

The SFP28 optical module has 2.5 times its optimum input/output performance and fiber capacity compared to the 10G optical module, with a higher port density, saving operational costs by reducing the number of ToR switches and cables. Compared to the 40G optical module, the SFP28 optical module is less expensive because the SFP28 optical module can use two optical fiber channels to achieve a 50G transmission rate, while the 40G optical module needs to achieve a 40G transmission rate through four 10G optical fiber channels. The SFP28 optical module has less loss than the 100G optical module.SFP28 series optical module products are to meet the data center, LTE/5G wireless access and other needs. it meet the transmission distance of 100m to 40km, operate temperature range: 0 to 70C or -40 to 85C, of which 25G SFP28 BIDI is specially tailored for 5G.

25G SFP28 Types

The SFP-25G-SR optical module conforms to multiple standards and specifications such as IEEE 802.3, SFF-8472, SFF-8402, SFF-8432 and SFF-8431, and is a SFP28 optical module with a central wavelength of 850nm, supporting DOM function.  The SFP-25G-SR optical module is suitable for short-range data transmission (up to 100m) and can be applied to short-distance data transfer in 25G Ethernet switches, routers, network interface cards (NICs) and storage network devices. SFP-25G-LR optical module also conforms to IEEE 802.3, SFF-8472, SFF-8402, SFF-8432 and SFF-8431 and other multiple standards and specifications, it is a central wavelength of 1310nm SFP28 optical module, With single-mode fiber when using the transmission distance of up to 10km, so the SFP-25G-LR optical module is mainly used for long-distance data transmission.

The further development of mobile Internet will bring about a thousand-fold growth of mobile traffic in the future and promote a new round of changes in mobile communication technology and industry. Mobile healthcare, car networking, smart home, industrial control, environmental monitoring, etc. will promote the explosive growth of Internet of Things applications, hundreds of billions of devices will be connected to the network, to achieve a true “Internet of Everything”, and create an unprecedented scale of emerging industries, for mobile communications to bring unlimited vitality.

At the same time, many devices and diversified Internet of Things business will bring new technical challenges to mobile communications. From 4G to 5G, the increase of network demand has brought about revolutionary changes in network technology, and the industrial structure has also changed significantly. In the 4G network mainly uses 10G optical module, because the 4G single RRU bandwidth only 1.25G, so in the 4G network ingress direction of the forward transmission using many chain-based networks structure to save fiber resources, reduce deployment difficulty. And 5G, because the forward bandwidth minimum needs 25G optical module, 100G optical module price relative to the price of 25G optical module slightly higher, so many people will choose 25G optical module and direct connection cable (AOC-DAC cable) as the solution, while limited by the impact of 25G optical module, Can no longer choose the previous chain network, must adopt the star network method.
