Make your high data rate interconnections with our compatible Huawei 25G SFP28 and 400G QSFP-DD transceivers for superior performance and cost-efficiency.

Huawei 25G & 400G Transceivers

This section covers compatible Huawei 400G QSFP-DD transceivers widely used in the Huawei CloudEngine series, as well as 25G SFP28 transceivers used in CloudEngine and S Series Switches. In recent years, the Huawei SFP28 transceiver portfolio has grown in popularity. The reason for this increase is that the speed of the 25G line is the highest that optical equipment can achieve using NRZ modulation, making it the most cost-effective and port-density-efficient transmission standard. The Huawei 25G portfolio includes SR and LR transceivers, as well as BiDirectional 25G SFPs with a distance of up to 10km. Huawei 400G should not be overlooked, it use QSFP-DD (Quad Small Form Factor Pluggable Double Density) form factor and support a new generation of 400G data rate. The Huawei compatible QSFP-DD form factor includes an additional row of contacts for an eight-lane electrical interface capable of 50G PAM4 modulation, resulting in 8x50G (400G) transmission capacity. Our Huawei 400G portfolio includes a short-range and a long-range transceiver that operate in a standard 0°-70°C temperature range.

25G SFP28 Transceivers

Our Huawei 25G SFP28 Compatibles enable you to create connections in two different manners. Firstly, by using the standard duplex with MMF for short distances or SMF for longer ones — typically for connecting remote sites. Or secondly, preserve SMF optical resources and build the same 25G connections utilizing BIDI WDM technology, which separates transmission directions using two distinct wavelengths—1270nm and 1330nm. Our Huawei 25G SFP28 transceiver alternatives support the IEEE 802.3by 25G standard but are also backwards compatible with SFP + ports meaning that our Huawei 25G SFP28 Compatibles will operate at 10G speeds when plugged into SFP+ ports. Besides the standard and BIDI 25G SFP28 transceivers, we are also able to provide other 25G solutions for applications such as CWDM, DWDM, Tunable and more. Employing our expertise, we are able to provide custom-tailored firmware and solutions for Huawei 25G to most Huawei platforms as CloudEngine, NetEngine, S series and more!


Huawei 400G QSFP-DD Compatibles have one of the highest Ethernet data rates, providing enhanced capabilities for major aggregation and high bandwidth connectivity applications. These applications include hyperscale data centers, internet exchanges, colocation services, wireless infrastructure core, service provider and operator core networks, and video distribution infrastructure. Our Huawei 400G QSFP-DD Compatibles portfolio consists of transceivers which can operate over Single-Mode or Multi-Mode optical Fiber, can be used for connection distances from a couple of meters up to 10 kilometers and can support up to 425 Gbps data rate and 400G Ethernet application. Thanks to the accumulated knowledge, we are also able to offer other types of 400G QSFP-DD which can be used in Huawei equipment for example DR4, ER8 and others, which are not included in this portfolio, but can be achieved with custom firmware!
