With the advent of the cloud computing and big data era, the network is forced to develop at a high rate and high density, and the utilization rate of the virtualization server is increased. In order to provide sufficient I/O (input/output) bandwidth, many new access switches have evolved into 2- or 4-port 40G Ethernet that can be connected to core switches. The rapid development of interconnected data transmission is inseparable from the 40G QSFP+ optical module, because it can provide enough bandwidth to ensure unimpeded data conversion, so as to meet the network and enterprise campus network needs. In this article, we will give you a detailed introduction to 40G QSFP+ optical modules and 40G QSFP+SR4 optical modules.
40G QSFP+ Optical Module Overview
The 40G QSFP+ optical module is a compact hot-swappable optical module with four transmission channels, each with a data rate of 10Gbps, and this optical module meets multiple standards such as SCSI, 40G Ethernet, and 20G/40G Infiniband. .
And the 40G QSFP+ optical module can transmit data at 10Gbps per channel under the same port volume of the XFP optical module, and simultaneously supports data transmission of four channels, so the density of the 40G QSFP+ optical module can be 4 times that of the XFP optical module. It is 3 times that of SFP+ optical modules.
The two basic interface specifications for QSFP+ optical modules are 40G SR4 and 40G LR4. The 40G QSFP+ SR4 optical module complies with the 802.3ba D3.2 standard and can be used with the MPO/MTP fiber optic connector to achieve 40Gbps optical connection. This optical module is also transmitted through four channels, and the transmission rate is consistent with LR4. In the data center, the 40G SR4 QSFP+ optical module can be used with multimode OM3/OM4 fiber to achieve 100m (OM3) and 150m (OM4) transmission, enabling interconnection between two Ethernet switches.
How does the QSFP+ 40G SR4 optical module work?
The working principle of the 40GBASE-SR4 optical module: When the signal is transmitted at the transmitting end, the electrical signal is first converted into an optical signal by the laser array. When the transmitting end transmits the signal, when the receiving end receives the signal, the photodetector array converts the parallel optical signal. Parallel electrical signals.

40G QSFP+ SR4 optical module 40G to 40G transmission application
40G to 40G transmission in a 40G fiber network environment. Insert two QSFP+ SR4 optical modules on the two 40G switches. Then the two optical modules can be connected by MTP trunk multimode fiber jumpers. This is the easiest way to connect QSFP + SR4 optical modules.
40G QSFP+ SR4 optical module 40G to 10G transmission application
The QSFP+ SR4 is a parallel optical module, which means that it uses four fiber interfaces for simultaneous reception. The 40G fiber optic signal can be divided into four 10G signals to meet the needs of 40G to 10G network transmission. The number of fiber cores increases at the 10G distribution end. It can usually be used to fuse MTP-8LC branch fiber patch cords. For better cable management, we recommend using a 1U 96-port chassis to connect the four 10G LC ports on the front of the MTP box to the HDMTP 40G port. Four 10G-SR SFP+ box enclosures, plugged into 10G switches/ports, can be connected to the corresponding LC ports for duplex network transmission between 40G and 10G.
