The main categories of HUAWEI optical modules are: SFP, SFP+, SFP28, QSFP+, QSFP28, etc, In this blog, ETU-Link will introduce these different packaging forms of optical modules.

HUAWEI SFP optical modules

SFP（SMALL FORM PLUGGABLE）, It has the advantage of miniaturization, it only has the thumb size, because it does not contain SerDes part, only provides a serial data interface, put CDR and electric dispersion compensation outside the module, so that small size and small power consumption are possible.

2G/4G/8G/16G SFP optical modules

HUAWEI SFP+ optical modules

As a small hot pluggable optical module, SFP+ has the advantages of high density, low power consumption and lower system construction cost. Its products are widely used in the field of 10 Gigabit Ethernet optical fiber data communication and are the mainstream products of 10 Gigabit module.

HUAWEI SFP28 optical modules

The optical module of SFP-25G-SR adopts the form of SFP28 package. The wavelength is 850nm. The transmission distance can reach 70m when using multimode optical fiber OM3 and 100m when using multimode optical fiber OM4. It is suitable for short-distance connection.

HUAWEI QSFP+ optical modules

QSFP+ optical module has 4 channels, and the pluggable interface transmission rate of each channel is 10Gbps. It is a compact hot plug optical module for data communication applications, with four independent optical signal transmission and reception channels, mainly used for high-speed data transmission of switches, routers and data center equipment.

HUAWEI QSFP28 optical modules

QSFP28 optical module is a kind of optical module that can be used to support 100G transmission. Compared with several previous 100G optical modules, QSFP28 has the advantages of miniaturization, which means that QSFP28 optical module has higher port density on the switch, and the power consumption of QSFP28 is much lower than other 100G optical modules, so it has certain advantages in the 100G optical module market.

The above is the main classification of common Huawei optical modules. ETU-Link lists the optical modules of the SFP, SFP+ , SFP28, QSFP+ and the QSFP28 optical module. Thank you for your support!
