Connect IBM G8264 Switch to 1G, 10G and 40G Network

Posted on by FS.COM

Flexibility is quite important to switches in the telecommunication network, especially those switches for layer 2 and layer 3 during network transition or upgrading. A switch that can support different data rates and transmission medias can greatly increase the flexibility of the telecommunication network and reduce cost at the same time. IBM G8264 is a good example of this kind of switch, which is considered particularly suited for a variety of applications in data center. How to connect IBM G8264 to the network will be introduced in this article in specific details.

Do You Know IBM G8264 Switch?

IBM G8264 is an ideal solution for applications like Big Data and Cloud. It is suggested to be used in the enterprise class at Layer 2 and Layer 3 delivering non-blocking line-rate, high-bandwidth switching, filtering, and traffic queuing without delaying data. As mentioned, the great flexibility of IBM G8264 is largely shown in the data rates that it can deliver. IBM G8264 switch not only supports the main demanded data rate of 10G and 40G, but also traditional 1G connection. In addition, both fiber optic based connection and copper based connection can be built with IBM G8264 switch, which satisfies the flexible needs in data center. Except flexibility, IBM G8264 is also ideal for latency sensitive applications like high performance computing clusters and financial applications, as it offers low latency during transmission. To further illustrate how to connect IBM G8264 to the network, ports on IBM G8264 switch will be first introduced in details.

The following picture shows IBM G8264 switch ports on its front panel. The main part of the front panel is engaged by 48 SFP/SFP+ ports which can deliver 1 or 10 Gigabit Ethernet. Beside them are four QSFP+ ports for 40 Gigabit Ethernet. There are three ports for other uses: one 10/100/1000 Ethernet RJ45 port for out of band management, one USB port for mass storage device connection and one mini-USE console port for serial access.

IBM G8264 Switch in 1G, 10G and 40G Network

IBM G8264 switch can be used for connections of 1G, 10G and 40G based on both fiber optic or copper according to the cables and connectors that used. To provide customers with solutions taking full advantages of IBM G8264 switch, this part will introduce how to connect IBM G8264 switch to 1G, 10G and 40G network separately.

IBM G8264 Switch 1G Connection

1G connection supported by IBM G8264 switch could be based on fiber optic or copper. For copper connection, the transmission distance up to 100 meters could be achieved by using RJ-45 1000BASE-T SFP transceivers with UTP cables. If you need to connect IBM G8264 switch to target devices that are located at longer distances, fiber optic connection is suggested. Using a 1000BASE-SX transceiver with 62.5μ multimode fiber optic cable, transmission distance up to 220 meters could be reached. If you use a 50μ multimode fiber optic cable with 1000BASE-SX transceiver, the transmission distance will increase to 550 meters. If all the above 1G connection solution cannot satisfy your distance needs, 1000BASE-LX transceivers and single-mode fiber are suggested, which can support distances up to 10 kilometers. Kindly check the following table for the related modules and cables for IBM G8264 switch 1G connection.

Transmission Media Module Cable & Connector Distance
Copper Cable BN-CKM-S-T: SFP 1000BASE-T copper transceiver RJ45, Cat5 cable 100 m
Fiber Optic Cable BN-CKM-S-SX: SFP 1000BASE-SX optical transceiver LC duplex, MMF 220 m(50μ multimode fiber)
550 m(62.5μ multimode fiber)
BN-CKM-S-LX: SFP 1000BASE-LX optical transceiver LC duplex, SMF 10 km

 

IBM G8264 Switch 10G Connection

The flexibility advantage of IBM G8264 switch can satisfy a variety of 10G connections in different situations. By using the proper cables and modules, customers can figure out the most economical and suitable solutions for 10G connection.

For 10G transmission in short distances, there are mainly two methods to connect the switch to the target devices. One is using DAC (direct attach cable) which is attached with a SFP+ module on both ends, eliminating the used of transceivers. However, the transmission distance is limited to 7 meters. If longer distances are required, 10GBASE-SR transceiver used with OM3 multimode fiber can support transmission distance up to 300 meters. If 10GBASE-SR transceive is used with OM4 fiber optic cable, distance up to 400 meters could be reached. Using 10GBASE-LR transceiver with single-mode fiber optic cable, IBM G8264 switch can be connected with target devices that are 40 kilometers away.

Another interesting tip: If you want to increase the 10G port number, the QSFP+ port on the IBM G8264 switch can be split into four 10G ports by using QSFP+ DAC breakout cables for distances up to 5 meters. For distances up to 100 meters, optical MTP-to-LC break-out cables can be used with the 40GBASE-SR4 transceiver. The following table listed the related products that are needed for different solutions of IBM G8264 switch connection.

IBM G8264 Switch 40G Connection

QSFP+ to QSFP+ DAC is a popular solution for IBM G8264 40G connections up to 7 meters, as it is affordable to most data centers. For transmission distances up to 100 m, the 40GBASE-SR4 QSFP+ transceiver can be used with OM3 multimode fiber and MTP connector, or up to 150 m when using OM4 multimode fiber with MTP connectors. For long distance 40G transmission, 40GBSE-LR QSFP+ transceiver and single-mode fiber optic cable with LC connectors are suggested to connect IBM G8264 with the target devices.
