Cisco QSFP-40G-CSR4 Overview

This Cisco QSFP-40G-CSR4 compatible QSFP+ transceiver provides 40GBase-SR4 throughput up to 400m over multi-mode fiber (MMF) at a wavelength of 850nm using a MPO connector. It is guaranteed to be 100% compatible with the equivalent Cisco transceiver. This easy to install, hot swappable transceiver has been programmed, uniquely serialized and data-traffic and application tested to ensure that it will initialize and perform identically. Digital optical monitoring (DOM) support is also present to allow access to real-time operating parameters. All of our transceivers are Trade Agreements Act (TAA) compliant.

Cisco QSFP-40G-CSR4 Compatible 40GBASE-CSR4 QSFP+ Optical Transceiver Module (MMF, 850nm, 400m, MTP/MPO, DOM)

The QSFP+ module is designed for use in 40GBASE Ethernet throughput up to 400m over multimode fiber (MMF) using a wavelength of 850nm via a MTP/MPO-12 connector. This transceiver is compliant with QSFP+ MSA, IEEE 802.3ba 40GBASE-SR4 and IEEE 802.3ae 10GBASE-SR standard. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP+ MSA, to allow access to real-time operating parameters. With these features, this easy to install, hot swappable transceiver is suitable to be used in various applications, such as data centers, high-performance computing networks, enterprise core, distribution layers.

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.
