32G Fibre Channel network is the sixth-generation channel technology. In the next 10 years, Fibre Channel will still be the preferred storage protocol for data centers. In this article, ETU-LINK will introduce the 32G SFP28 FC multi-mode（MM) optical module and its application in the data center 32G storage network SAN.

32G SFP28 FC MM optical module (ES2853X-3LCD01) adopts hot-swappable SFP28 package, equipped with 850nm VCSEL laser and PIN photodetector. It complies with SFP28 MSA and 32G fiber channel standards. Meanwhile, it is backwardly compatible with 8G/16G fiber channel standard, and the highest rate is up to 28.05Gbps.

The 32G SFP28 FC MM optical module has a dual-fiber LC interface, which can transmit up to 70 meters through MM fiber OM3, and can transmit up to 100 meters through MM fiber OM4. The operating temperature range include industrial (-40℃-85℃). ) and commercial grade (0℃-70℃).

The 32G FC fiber channel optical module is mainly used in the fiber channel switch and HAB fiber network card in the 32G SAN storage network. It can realize the interconnection between the 32G storage network equipment and form a SAN network.

The use of SAN storage technology can improve the storage network management mechanism, and carry out flexible management and online monitoring of all storage devices, such as disk arrays and tape libraries. At the same time, this can realize LANfree, data transmission, replication, migration, backup, etc. at high speed in the SAN storage network without occupying network resources.

SAN technology is oriented to the high-speed processing of large-capacity data and multiple servers, including high-speed access, secure storage, data sharing, data backup, data migration, disaster recovery and other aspects. In addition, SAN technology has important practical value for applications in telecommunications, video, Internet ICP/ISP, petroleum, surveying and mapping, finance, meteorology, library management, military, radio and other industries.
