How to Choose the Right LSOLINK SFP28 Product

Selecting the right LSOLINK SFP28 product requires starting from the actual application scenario and comprehensively considering factors such as transmission distance, bandwidth requirements, cost budget, and device compatibility.

Transmission distance is the primary factor. For short-distance connections between devices within data center racks, the 25G-SFP-SR multimode optical transceiver or the 25G-SFP-CU passive copper cable can be the preferred choice, meeting high-speed transmission requirements while maintaining cost advantages. When the transmission distance is within 10km, such as inter-room connections within data centers or inter-building links in enterprise campuses, the 25G-SFP-LR single-mode optical transceiver with single-mode fiber is an ideal option. For long-distance transmission up to 40km, the 25G-SFP-ER ensures stable data delivery, suitable for metropolitan area network (MAN) applications.

Bandwidth demand and network upgrade planning are also crucial. For enterprises currently requiring only 10Gbps but planning to upgrade to 25Gbps in the future, the 10/25G-SFP-SR and 10/25G-SFP-LR dual-rate optical transceivers provide a smooth migration path, avoiding repeated investments. If bandwidth requirements are extremely high and fiber resources are limited, CWDM or DWDM optical transceivers can significantly increase transmission capacity by carrying multiple wavelength signals over a single fiber through wavelength-division multiplexing technology.

Cost and fiber resource availability also impact selection decisions. If fiber resources are abundant, conventional optical modules are sufficient. If fiber resources are limited, BiDi single-fiber bidirectional transceivers such as 25G-SFP-U23-20 and 25G-SFP-D32-40 can save half the fiber resources and reduce cabling costs. In addition, passive copper cables are more cost-effective than active optical cables (AOC) for short-distance transmission. For medium and long-distance transmission, although AOCs have a higher initial cost, their advantages in anti-interference capability and lighter weight make them more cost-effective in the long run.

Device compatibility is another key consideration. All LSOLINK SFP28 products undergo rigorous testing with mainstream networking equipment vendors such as Cisco, HPE, and Huawei. However, before procurement, it is still necessary to provide specific device models to ensure compatibility and avoid potential issues.
