Different Applications for 10G SFP+ Cable

Share

10G SFP+ cables are of various kinds, including DACs, AOCs, and other 10G SFP+ optics (10GBASE-SR/LR/ER/ZR and 10GBAE-T copper transceivers) plus patch cables and copper cables, which are widely adopted in data centers to connect servers, storage appliance and switches. Each of them has different application for different distance. Next, we will talk about these cables respectively.

10G SFP+ DAC Cable: Server to Switch Connectivity

10G SFP+ DAC cable (Direct Attach Cable) is a type of sheathed high-speed cable featuring SFP connectors on either termination. The main utility of direct attach cables lies in connecting server to switch within the rack. Top-rack interconnections in data centers are made of 10g direct attach cables these days to provide better alternative to RJ 45 connectors, which are losing their foothold because of the bulkier interface and availability of very few equipment and protocol appearing in their compatibility matrix. For any short range connection measuring as small as 5 m to 10 m, a better performing direct attach cable offers easier and more affordable solution. Servers are typically connected to a switch within the same racks. 10G SFP+ DAC twinax cable supports link length up to 7 m, making it perfect for servers to switch connections.

FS 10G SFP+ DAC cables are available with different lengths with customized services being offered too. And every cable is individually tested on corresponding equipment such as Cisco, Arista, Juniper, Dell, Brocade and other brands, having passed the monitoring of FS intelligent quality control system. Part of the products are shown in the picture below.

10G SFP+ AOC Cable: Switch to Switch Connectivity

10G SFP+ AOC cable (Active Optical Cable) assemblies are high performance, cost effective I/O solutions for 10G Ethernet and 10G Fibre Channel applications, which can also be used as an alternative solution to SFP+ passive and active copper cables while providing improved signal integrity, longer distances, superior electromagnetic immunity and better bit error rate performance. They allow hardware manufactures to achieve high port density, configurability and utilisation at a low cost and a reduced power budget. Unlike 10G SFP+ DAC cable, which is often applied in short distance, 10G SFP+ AOC cables can achieve transmission distance up to 100 m, so they often used in switch to switch connections.

10G SFP+ Cables

FS active optical cable (AOC) assemblies use active circuits to support longer distances than standard passive or active SFP+ Copper Cables. FS offers Cisco compatible AOC which is designed for high speed, short range data link via optical fiber wire.

10G SFP+ Optics: Server/Storage to Switch Connectivity

10G SFP+ transceivers, including 10GBASE-SR/LR/ER/ZR and 10GBASE-T copper transceiver, are designed for CWDM and DWDM applications. The range of transceivers supports 850nm, 1310nm, 18 channel for CWDM applications and 40 channels for DWDM applications. These optical transceivers are available with short haul or long haul receivers. Since server or storage to switch connection requires reliable, scalable and high-speed performance, transceivers plus patch cables are usually adopted to achieve such a connection.

10G SFP Cables

FS 10G transceivers are of various types, including GBIC, SFP+, XFP, X2, XENPAK optics, which can be deployed in diverse networking environments. With an industry-wide compatibility and strict test program, FS 10G SFP+ modules can give customers a wide variety of 10 Gigabit Ethernet connectivity options such as server/storage to switch connectivity.

Conclusion

Different 10G SFP+ cables are selected for different distance and application. Generally speaking, 10G SFP+ DAC cable is perfect for short reach applications within racks, while 10G SFP+ AOCs are suitable for inter-racks connections between ToR and EoR switches. With excellent quality and lifetime warranty, FS 10G optics brings real-time network intelligence to the financial services market at 10 Gbps speeds.
