40 GbE QSFP+ CSR4

Hi,

 

I have a site that's going to install two MS425 they will be connected by 40 GbE QSFP+ CSR4, my question is, what cable can I use for this connection.

 

Thanks

@Inderdeep the customer just indicated that they will have the MS425 in two separate wiring closets, the distance between them is about 200m, can the  40GbE QSFP+ CSR4 support this distance?

CSR4 is a multimode connector and no, 400m max.

 

Cisco QSFP-40G-CSR4

Cisco 40GBASE-CSR4 QSFP Modules extend the reach of the IEEE 40GBASE-SR4 interface to 300 and 400 meters on laser-optimized OM3, and OM4/OM5 multimode parallel fiber, respectively. Each 10-gigabit lane of this module is compliant to IEEE 10GBASE-SR specifications. This module can be used for native 40G optical links over 12-fiber parallel cables with MPO/MTP female connectors or in a 4x10G breakout mode with parallel to duplex fiber breakout cables for connectivity to four 10GBASE-SR interfaces. Cisco QSFP-40G-CSR4 is optimized to guarantee interoperability over the complete specification range of 10GBASE-SR.

 

You need the LR4

 

Cisco QSFP-40G-LR4

The Cisco 40GBASE-LR4 QSFP module supports link lengths of up to 10 kilometers over a standard pair of G.652 single-mode fiber with duplex LC connectors. The 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.
