The adoption of 100G QSFP28 transceivers in data centers is widespread due to their exceptionally high speed of over 100 Gbps which corresponds to the escalating levels of data communication traffic. As a faster connetivity option, the 100G QSFP28 transceiver is becoming more popular for use in data centers. This article discusses some of the pertinent considerations when selecting a 100G QSFP28 transceiver.
Design parameters such as dimensions, outline, and electrical interface make up the form factor of the transceiver. Variants of QSFP28 transceivers that are available with different form factors include, but are not limited to, SR4, CWDM, LR4, PSM4, and CLR4. With regards to your network devices, such form factors are important to consider, even though not all of them are essential. As not all network devices accept all form factors, one has to be prudent to avoid financial losses due to overlooking form factor compatibility.
The type of interface used by the 100G QSFP28 transceiver determines the specific port it can connect to on your network device. Identify the port on your device and establish if your transceiver corresponds to its connectivity type. InfiniBand whiskers are also available for some transceivers which have copper and fiber interfaces. Select the transceiver which provides the appropriate connector type based on the cabling scheme used in your network. Some prevalent types of connectors are LC, MPO and the copper QSFP connector.
The operational distance of a transceiver is determined by its wavelength and the duplex parameter. The 100G QSFP28 transceiver is mostly used with single-mode, multi-mode, or copper-wired cables. The type of multiplexing applied also has an impact on the wavelength; In this case, WDM and CWDM must be selected. The WDM method uses wavelengths in the range of 1271—1331 nm, while the CWDM method is capable of supporting a wider range of different wavelengths. For the optimum achievable range using a particular use case, ensure that the necessary parameters – duplex and wavelength – are set appropriately corresponding to the distance.
Multi-source agreement compliance guarantees interoperability of the 100G QSFP28 transceiver with other network equipment. An MSA establishes a standard interface between network equipment and transceivers for greater functionality. Verify that the corresponding MSA is transceiver compliant, specifically the QSFP28 MSA, where the port, transceiver, and cable are guaranteed to work together.
Choosing a 100G QSFP28 transceiver also necessitates paying attention to IEEE compliance. The specifications regulate how interconnections are made to the transceiver, its electrical and optical performance, and the safety boundaries within which the system is allowed to operate. Some of the most important IEEE specifications are often IEEE 802.3bj, 802.3bm, and the 802.3 Ethernet standards. Make certain that the 100G QSFP28 transceiver completely complies with the prescribed IEEE safety standards, so network complications and breakdowns are circumvented.
In conclusion, any data center will optimize performance by selecting the correct 100G QSFP28 transceiver. MSA compliance, IEEE compliance as well as form factor, connectivity, wavelength and duplex type are the most important features to look at when selecting your 100G QSFP28 transceiver. Evaluate these aspects to eliminate compatibility problems that would limit network efficiency.
