The previous storage technology only uses the storage device as an auxiliary device of the server. The large-capacity data exchange between servers can only rely on traditional networks, and cannot adapt to the development of IT technology in terms of speed, security, cross-platform sharing, and unlimited expansion. Under such circumstances, SAN technology came into being. fiberChannel SCSI technology is the physical foundation of SAN technology. When building a 32G SAN storage network, in addition to fiberChannel switches, HBA fiber optic network cards and other equipment, 32G SFP28 FC optical modules and fiber jumpers are required as transmission carriers. Next, Walsun will introduce the types and applications of 32G SFP28 FC single-mode optical modules.
1.32G FC SFP28 LR 10km（ES2313X-3LCD10）
It adopts hot-swappable SFP28 package, dual-fiber LC interface, working wavelength of 1310nm, equipped with DML laser and PIN photodetector. Meanwhile,it conforms to SFP28 MSA and 32G fiber channel standards, and is backward compatible with 8G/16G fiber channel standards. The maximum rate is up to 28.05Gbps, and the maximum transmission distance is 10 kilometers through the single-mode optical fiberOS2.
2.32GFC SFP28 ER 40km（ES2313X-3LCD40）
It adopts hot-swappable SFP28 package, dual-fiber LC interface, working wavelength of 1310nm, equipped with EML laser and APD photodetector. Besides,it conforms to SFP28 MSA and 32G fiber channel standards, and is backward compatible with 8G/16G fiber channel standards. The highest rate is up to 28.05Gbps, and the maximum transmission distance is 40 kilometers through single-modeoptical fiber OS2.
3.32GFC CWDM SFP28 10km（ES2Cxx3X-3LCD10）
It adopts hot-swappable SFP28 package, dual-fiber LC interface, optional working wavelength of 1270nm-1610nm (interval 20nm), equipped with CWDM DML laser and APD photodetector. In addition,it meets SFP28 MSA and 32G fiber channel standards.It is backward compatible with 8G/16G fiberChannel standard, the highest rate is up to 28.05Gbps, and it can transmit up to 10 kilometers through single-mode optical fiber OS2.
4.32GFC DWDM SFP28 10km（ES2Dxx3X-3LCD10）
It adopts hot-swappable SFP28 package, dual-fiber LC interface, optional working wavelength C17-C61 (interval is 100Hz), equipped with DWDM EML laser and PIN photodetector. Additionally,it conforms to SFP28 MSA and 32G fiber channel standards.It is backward compatible with 8G/16G fiberchannel standard, the highest rate is up to 28.05Gbps, and it can transmit up to 10 kilometers through single-mode optical fiberOS2.
The 32G SFP28 FC single-mode optical moduleis used for the interconnection of long-distance fiber channel switches and HBA optical network cards, becoming an indispensable transmission carrier for building a SAN storage network.
