MA-QSFP-40G-SR4

Ultimate Solution for Faster Data Transmission

The Cisco MA-QSFP-40G-SR4 transceiver is designed to work with Cisco Meraki network equipment. This is a small form-factor transceiver that provides faster communication between switches and other networking components. 

Cisco MA-QSFP-40G-SR4 Compatible QSFP+ Transceiver adopts 12 Fibers MTP/MPO Male connectors, reaching a link up to 150m over OM4 MMF (100m over OM3). It is configured and verified to work with Meraki data center switches, routers, network interface cards (NICs), and other optical transport devices in 40G Ethernet and high-performance computing networks applications. 

It is an excellent substitute for OEM transceivers at a much lower cost. However, QSFP-40G-SR4 transceivers are also Cisco Compatible Transceivers and can be compatible with Cisco Meraki network equipment and has a lot of features and benefits similar to Cisco MA-QSFP-40G-SR4 transceivers.

Let’s understand more about the QSFP-40G-SR4 transceivers in this article.

Cisco QSFP-40G-SR4 Transceivers

The Cisco compatible transceivers of 40GBASE-SR4 QSFP Modules provide connection lengths of 100 and 150 meters on laser-optimized OM3 and OM4/OM5 multimode fibers, respectively. Its primary use is to provide high-bandwidth 40G optical communications via 12-fiber parallel fiber terminated with MPO/MTP multi fiber female connectors. 

It can also be utilized in a 4x10G breakout mode for compatibility with 10GBASE-SR and SFP-10/25G-CSR-S (in 10G mode) interfaces on OM3 and OM4/OM5 fibers up to 100 and 150 meters, respectively. 

The  4x10G mode operation is enabled by optimizing the Cisco QSFP-40G-SR4’s transmit and receive optical characteristics to prevent receiver overload or unnecessary triggering of alarm thresholds on the 10GBASE-SR and SFP-10/25G-CSR-S (in 10G mode) receivers, while remaining fully interoperable with all standard 40GBASE-SR4 interfaces.

An external 12-fiber parallel to 2-fiber duplex breakout cable links the 40GBASE-SR4 module to four 10GBASE-SR optical ports, allowing for 4x10G connection. 

Cisco QSFP-40G-SR4 transceivers are designed to work with any:

  •  IEEE 40GBASE-SR4 and, in 4x10G mode, 
  • 10GBASE-SR and SFP-10/25G-CSR (in 10G mode).

Features and benefits of Cisco Transceivers QSFP modules

  •     Hot-swappable input/output device that plugs into a 40 Gigabit Ethernet Cisco QSFP port

FAQ's

QSFP modules are typically available in a variety of configurations: 4 x 1 Gbps QSFP, 4x10Gbps QSFP+, 4x28Gbps QSFP28. The most recent variants, QSFP+ and QSFP28, offer a wide range of 40 Gbps and 100 Gbps applications. Both the QSFP+ and QSFP28 modules have four transmit and four receiver channels.

Cisco QSFP-40G-SR4 transceivers support multimode fiber connections.

It can transmit data at up to 40 Gigabits per second.

No, it is compatible only with multi-mode fiber optic cables

The typical maximum reach is around 100 meters.

Yes, it complies with various industry standards and protocols

No, Cisco QSFP-40G-SR4 cannot be used in a 10G or 100G network environment as it is designed specifically for 40G network environments.

The Cisco 40GBASE-SR4 QSFP Modules provide connection lengths of 100 and 150 meters on laser-optimized OM3 and OM4/OM5 multimode fibers, respectively. Its primary use is to provide high-bandwidth 40G optical communications via 12-fiber parallel fiber terminated with MPO/MTP multi fiber female connectors. Cisco 40GBASE-CSR4 QSFP Modules increase the IEEE 40GBASE-SR4 interface's reach to 300 and 400 meters, respectively, using laser-optimized OM3 and OM4/OM5 multimode parallel fiber.
