Brocade 40G Switch ICX 7750-26Q Cabling Solution

The Brocade ICX 7750 is a series of switches which can provide high-availability capabilities and flexible stacking architecture for 10/40G applications. Brocade ICX 7750 series switches are usually used for 10/40G aggregation and core distribution. Brocade ICX 7750-26Q is a member of Brocade ICX 7750 series, which is a 1U high performance switch with up to 32 40G QSFP+ ports (six optional). This post will offer optics and cabling solution for Brocade ICX 7750-26Q switches.

Basic of Brocade ICX 7750-26Q Switch

The above picture shows a Brocade ICX 7750-26Q switch from FS.COM testing center. On the front panel of Brocade ICX 7750-26Q switch, there are 26 40G QSFP+ ports, ICX 7750-6Q module with 6 40G QSFP+ ports can be added on the rear panel of this switch. Thus up to 32 40G QSFP+ ports can be supplied by Brocade ICX 7750-26Q switch. It can support transmission applications for both 40G to 40G and 40G to 10G.

Brocade ICX 7750-26Q 40G to 40G Applications

Brocade ICX 7750-26Q can support 40G transmission for both short distances and long distances by using different 40G QSFP+ transceivers and fiber optic cables. The following picture shows the cabling methods for 40G point to point connection. Choosing the proper fiber patch cable for two QSFP+ modules, 40G data transmission between two Brocade ICX 7750 switches can be achieved. In this case, two Brocade 40G-QSFP-LR4 compatible transceivers and a length of LC to LC duplex single-mode fiber patch cable are being used.

Brocade compatible QSFP+ to QSFP+ direct attach cables including (direct attach copper cables and active optical cables) are cost-effective alternatives for Brocade ICX 7750-26Q 40G connections in short distances.


Brocade ICX 7750-26Q 40G to 10G Applications

As mentioned Brocade ICX 7750-26Q switch can also support 40G to 10G applications. A 40G QSFP+ port can be splitted into four 10G SFP+ ports, which can achieve transmission between 10G and 40G. There is a wide selection of Brocade ICX 7750-26Q switch 40G to 10G connections. Fanout assemblies play an important role to support these connections.

The above picture shows the commonly used connection methods for Brocade ICX 7750-26Q 40G to 10G connections. In this case, Brocade QSFP-40G-PLRL4 compatible transceiver is being used one the Brocade ICX 7750-26Q side. A length of MTP to four duplex LC breakout cable is being used to connect Brocade QSFP-40G-PLRL4 with four 10G SFP+ transceivers inserted in several 10G switches on the opposite side. Also, QSFP+ to SFP+ DACs and AOCs can also be used.
