What Factors Should Be Considered When Purchasing Fiber Optic Transceivers?

With the rapid development of the communication industry and data centers, the demand for fiber optic transceivers has increased sharply. In addition to original equipment manufacturer (OEM) fiber optic transceivers, there are also third-party fiber optic transceiver manufacturers. So, how should we choose fiber optic transceivers?

Types of fiber optic transceivers

Firstly, we need to choose the type of fiber optic transceivers based on the type of equipment ports, transmission distances, and compatibility. If it is a gigabit SFP port, a gigabit SFP fiber optic transceiver is required. Then, we can determine the transmission distance based on the distance between the two devices. Multi-mode fiber optic transceivers can be used for short distance transmission, while single-mode fiber optic transceivers should be used for long distance transmission. The maximum transmission distance of a single-mode fiber optic transceiver can usually reach dozens of kilometers.

If there is already a wiring system, we need to choose the interface type of the fiber optic transceiver based on the interface type on the fiber optic distribution frame, such as SC connectors for gigabit fiber optic transceivers. Finally, we need to consider the compatibility of the fiber optic transceiver. Different brands of switches have their own encryption methods during transmission, so a fiber optic transceiver that is compatible with the switch brand is needed for optical transmission.

Cost-effectiveness of fiber optic transceivers

  • Check the warranty period. The warranty period of OEM fiber optic transceivers is usually one year, while the warranty period of compatible fiber optic transceivers is more than three years.

  • Regarding the compatibility issue of fiber optic transceiver modules, many fiber optic transceiver module manufacturers do not have many models of brand switches, which may result in the inability to conduct compatibility tests on the fiber optic transceiver module. Professional fiber optic transceiver manufacturers will conduct 100% compatibility tests on fiber optic transceivers for different brands of switches before they are shipped.

  • It is difficult to determine the quality of a fiber optic transceiver module based on its appearance alone. We need to run the fiber optic transceiver module on a system for a period of time to assess its quality. Therefore, evaluating the quality of fiber optic transceiver module manufacturers is a relatively long process. We can test multiple compatible fiber optic transceiver modules and compare to find the most cost-effective supplier of compatible fiber optic transceiver modules.

  • When purchasing fiber optic transceiver modules, pre-sales and after-sales services are important. We can indirectly reflect the professionalism of a company by its sales staff during the sales process. When selecting fiber optic transceiver modules, we should not just focus on price, but should also understand related product knowledge. Fiber optic transceiver modules are not fast-moving consumer goods, so we need to carefully consider when purchasing them to avoid problems in the future. Therefore, it is necessary to consult with the manufacturer before the sale.
