What is 40G QSFP+?

QSFP+ stands for Quad Small Form-Factor Pluggable Plus. A parallel and hot-swappable fiber optical module that provides high-density 40G connectivity options for high-performance computing networks and modern data centers.

What is Cisco QSFP?

The Cisco QSFP 40-Gbps BiDirectional (BiDi) transceiver (Figure 1) is a pluggable optical transceiver with a duplex LC connector interface for short-reach data communication and interconnect applications using MultiMode Fiber (MMF). Like the QSFP BiDi transceiver, it has a duplex MMF LC connector interface.

What is the difference between QSFP and QSFP+?

QSFP28 can do 4x25G breakout connection, 2x50G breakout, or 1x100G depending on the transceiver used. While QSFP+ supports the data rate of 40G, 4 channels for transmitting and 4 channels for receiving, each lane carrying 10G. QSFP+ can break out into 4x10G or 1x40G connection.

What is Qsfp used for?

The Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggable transceiver used for data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA) under the auspices of the Small Form Factor Committee.

What is SR4 and LR4?

The most obvious difference is that 40GBASE-SR4 is with MPO/MTP port while the 40GBASE-LR4 is with the Duplex LC port. The following table summarizes the differences between QSFP+ transceiver optical interfaces and electrical interfaces. The cost of 40GBASE-SR4 QSFP+ is more cheaper than the 40GBASE-LR4 QSFP+.

Is QSFP+ Compatible with SFP+?

When you want to connect a QSFP+ port to a SFP+ port, you can use QSFP+ to SFP+ cable, QSFP+ to SFP+ adapter or QSFP+ breakout cable. FS.COM provides a full range of compatible QSFP+ cable, which can be 100% compatible with your Cisco, Juniper, Arista and Brocade switches and routers.

How do I get rid of QSFP?

Grasp the QSFP transceiver pull tab and gently pull the tab straight out. Note: Grasp the pull tab near the body of the transceiver to reduce the chances of bending the pull tab. Because the QSFP may be hot, avoid touching it.

What is Cisco BiDi?

The Cisco QSFP BiDi transceiver offers the industry’s most cost-effective solution for 40-Gbps connectivity. By transmitting full-duplex 40 Gigabit Ethernet over a duplex multimode fiber (MMF), it helps enable seamless 10 to 40 Gigabit Ethernet migration over your 10 Gigabit Ethernet fiber infrastructure.

What speed is QSFP?

1 Gbps
QSFP data rates get up to 1 Gbps per channel, allowing for 4X1 G cables and stackable networking designs that achieve better throughput. QSFP+ is the modern incarnation of QSFP. In most data centers, it has completely replaced its predecessor. QSFP+ can reach speeds of 10 Gbps per line.

Can SFP28 run at 10gb?

The pinouts of SFP28 and SFP+ connectors are mating compatible. However, SFP+ is designed to operate at speed up to 10 Gb/s whereas SFP28 can handle 25Gbps, 10Gbps and even 1Gbps.

What is LR4 SFP?

What Is QSFP28 LR4? The QSFP28 LR4 is a hot-pluggable, four-channel, and full-duplex optical transceiver module designed for long-distance transmission up to 10km in the 100G Ethernet network with a working bandwidth of 1295nm to 1310nm.

Which is Cisco qsfp-40g-sr-BD compatible optical transceiver?

The Cisco QSFP-40G-SR-BD compatible QSFP+ Optical Transceiver Module is designed for use in 40GBASE Ethernet throughput up to 150m over OM4 multimode fiber (MMF) using a wavelength of 832nm to 918nm via an LC connector.

Is the Cisco qsfp-40g-sr4’s compatible with FCoE?

QSFP-40G-SR4-S does not support FCoE. The Cisco 40GBASE-LR4 QSFP module supports link lengths of up to 10 kilometer over a standard pair of G.652 single-mode fiber with duplex LC connectors. The QSFP-40G-LR4-S module supports 40GBASE Ethernet rate only. The 40 Gigabit Ethernet signal is carried over four wavelengths.

What kind of fiber does the Cisco 40gbase QSFP module use?

The Cisco 40GBASE-ER4 QSFP Module supports link lengths up to 40km over G.652 single-mode fiber with duplex LC connectors. The 40GE or OTU3 signal is carried over four wavelengths in the 1310nm range. Multiplexing and demultiplexing of the four wavelengths are managed within the device.

What kind of optical transceiver is Cisco 40g-csr?

The QSFP-40G-CSR-S is a pluggable optical transceiver with a duplex LC connector interface used for connectivity using MultiMode Fiber (MMF). The Cisco 40GBASE-CSR Modules support link lengths of 300 and 400 meters, respectively, on laser-optimized OM3, and OM4/OM5 multimode fibers.
