The entry of optical fiber greatly meets the needs of users for the network, the optical module is the optical communication network to achieve photoelectric conversion, the transmitter converts the electrical signal into an optical signal, and after it is transmitted through the optical fiber, the receiver converts the optical signal into electrical signal. When choosing the optical module, it is not that the more expensive or the larger the capacity is the best, the one that suits you is the best. Yi Tianguang Communication ETU-LINK recommends a cost-effective optical module product-25G SFP28 LR. This product will not be like 40G/100G optical module high cost, power consumption is too high, and 10G optical module can not meet the current user needs of the network, so 25G SFP28 LR has been favored by most people.

What is a 25g SFP28 LR optical module

25g SFP28 LR is an optical module with a transmission rate of 25Gbps, a hot-swappable SFP28 package, a central wavelength of 1310nm, and a transmission distance of up to 10Km when used with single-mode fiber.

It supports DDM (Digital Diagnostic Monitoring) digital diagnosis function, which can monitor the working temperature, working voltage, working current, transmitting power and receiving power of the module in real time.

The optical interface adopts double LC sockets with high port density, and the 25G SFP28 LR optical module adopts DFB laser and PIN photodetector, LC duplex interface, transmitter and receiver with built-in CDR, which is mainly used in 25G Ethernet.

25g SFP28 LR product parameters

Energy saving and cost are two important factors to consider when deploying a network in a data center.
