The 100G QSFP28 transceiver is a pluggable fiber optic module that supports blazing-fast data rates of up to 100 Gbps. This article discusses the critical factors to consider when choosing a 100G QSFP28 transceiver.
The form factor refers to the transceiver’s size, shape, and electrical interface. QSFP28 transceivers come with various form factors, including SR4, CWDM, LR4, PSM4, and CLR4. While the form factor is not an essential consideration, it is crucial to determine the form factor compatibility with your network equipment. Not all network devices support all form factors, so scale carefully to avoid wastage of network investments by overlooking compatibility.
The connectivity of the 100G QSFP28 transceiver determines whether the transceiver can connect to the correct port on your network device. Identify the port on your device and check if your transceiver matches its connectivity type. QSFP28 transceivers come with fiber and copper interfaces; some even support InfiniBand connectivity. Consider the type of cabling that your network uses and choose a transceiver that matches the suitable connector. Some popular connector types include LC, MPO, and copper QSFP.
Wavelength and Duplex:
The wavelength and duplex settings of the transceiver dictate the distances over which it operates. Typically, the 100G QSFP28 transceiver operates over single-mode, multi-mode, or copper cabling. The multiplexing method also affects the wavelength – choose between WDM or CWDM. The WDM method uses wavelengths between 1271-1331 nm, while the CWDM method supports wavelengths over a more extensive range. Be sure to choose the correct wavelength and duplex settings for the distance requirements of your use case.
Multi-source agreement (MSA) compliance ensures interoperability and compatibility between the 100G QSFP28 transceiver and other network devices. MSAs provide a standardized interface between network devices and transceivers, allowing plug-and-play functionality. Ensure that the transceiver complies with the appropriate MSA, such as the QSFP28 MSA, which ensures the transceiver, port, and cable compatibility.
IEEE compliance is another crucial factor when choosing a 100G QSFP28 transceiver. IEEE specifications dictate the electrical and optical performance of the transceiver and ensure that they operate within safety limits. The critical IEEE specifications include IEEE 802.3bj, IEEE 802.3bm, and IEEE 802.3 Ethernet standards. Ensure the 100G QSFP28 transceiver meets all the necessary IEEE safety regulations to avoid network problems and failures.
