The Complete Guide to QSFP-40G-SR4 Transceiver Module

Introduction: What is QSFP-40G-SR4?

QSFP-40G-SR4 is a 40GBASE-SR4 QSFP+ transceiver module. It is designed for use in 40G Ethernet links over multimode fiber optic cables.

The QSFP-40G-SR4 is a high performance, low power consumption, hot pluggable transceiver module that provides four lanes of 10 Gigabit Ethernet data per second (10 Gbps) over multimode fiber optic cables. The QSFP-40G-SR4 supports the IEEE 802.3ae 10GBASE-SR specification and the IEEE 802.3ba 40GBASE-SR specification for data rates up to 40 Gbps per lane on multimode fiber optic cables with a maximum reach of 150 meters.

What are the Advantages of QSFP-40G-SR4?

The QSFP-40G-SR4 is a 40GBASE-SR4 QSFP+ transceiver module. It is designed for use in 40G Ethernet links with a maximum reach of 150m.

The advantages of the QSFP-40G-SR4 are:

1) The module has a low power consumption and can be used in data centers with high power efficiency.

2) The module has excellent performance and can be used in data centers with high performance requirements.

3) The module has excellent reliability and can be used in data centers with high reliability requirements.

4)The module can be connected with 10GBASE-SR in MTP-LC breakout cable.

5)Support hot pluggable and SFF 8436 MSA Compliant

6)Lowest price compared to other 40g modules or 100G-SR4 module.

What are the applications of QSFP-40G-SR4?

It is designed for use in data center applications and provides a cost-effective way to extend the reach of 40G Ethernet links.The QSFP-40G-SR4 is a 40G networking module that provides 4x10G connectivity to the distribution layer. This module is designed for use in 40 Gigabit Ethernet networks and can be used in both copper and fiber optic cable environments.

The QSFP-40G-SR4 allows data to be transmitted at speeds of up to 10 Gbps per channel, which means that it can transmit data at a total of 40 Gbps. It is also backward compatible with older 10 Gbps networks, so it can be used with those as well.

Besides, it also can be used in the data center networks to provide 40 GbE connections to servers, storage and network equipment. The QSFP-40G-SR4 is designed for data centers that need improved bandwidth without increasing their power consumption.

The QSFP-40G-SR4 can be used in various applications such as edge computing, data centers, and cloud computing environments where the need for increased bandwidth is required.

When we choose to use 40G optical modules, we need to choose according to the type of optical cable and the length of the link. If the application scenario is inside a building or rack, the qsfp-40g-sr4 is the most suitable choice. qsfp-40g-lr4 is more suitable for campus network and campus network. Cost is the focus of data center construction, so you should try to choose QSFP-40G-SR4.

The difference between QFSP-40G-SR4 and QSFP-40G-LR4

The difference between qsfp-40g-lr4 and qsfp-40g-sr4 is the distance and power consumption.

The qsfp-40g-lr4 has a longer reach than the qsfp-40g-sr4 (1,0000 meters vs. 150 meters). The power consumption of the qsfp-40g-sr4 is lower than that of the qsfp-40g-lr4 (0.8 watts vs. 1.5 watts). Besides, the qsfp sr4 adopted mtp-12 interface, which is different from the lc duplex interface. The QSFP28 40g SR4 must be used with mmf fiber, instead the qsfp+ 40g lr4 works on smf fiber. The transmitter of 40g lr4 is DFB laser which is more expensive than the vcsel of 40g sr4 and also has better performance. Price of QSFP28-100G-LR4 is much higher than qsfp-40g-lr4. When we choose to use 40G optical modules, we need to choose according to the type of optical cable and the length of the link. If the application scenario is inside a building or rack, the qsfp-40g-sr4 is the most suitable choice. qsfp-40g-lr4 is more suitable for campus network and campus network. Cost is the focus of data center construction, so you should try to choose QSFP-40G-SR4.
