The 40G SR4 optical module is an optical module with a transmission rate of 40G, 4-channel short-distance transmission, and is packaged as QSFP+. At present, 40G QSFP+ optical modules are widely used in various optical networks due to their various advantages, such as providing high-speed optical/electrical performance with low power consumption, the port density of QSFP+ modules using bundled fiber optic cables and MPO connectors is Three times the normal SFP+ modules and so on. In this article, we will talk to you about the meaning, installation and maintenance of 40G QSFP+ SR4 optical modules in detail.
First of all, QSFP+ is a 40G optical module package form defined by the IEEE organization, which greatly meets the market’s demand for high density and high speed. 40GQSFP+ optical module is a compact hot-plug optical module, it has four transmission channels, the data rate of each channel is 10Gbps, and this optical module complies with SCSI, 40G Ethernet, 20G/40G Infiniband and other standards. And there are multiple types of 40G QSFP+ optical modules, and SR4 is one of them.
The 40GBASE-SR4 optical module adopts MTP/MPO interface, and the working wavelength is 850nm, which is generally used in multimode applications. When it is used with OM3/OM4 multimode fiber, the transmission distance is 100 m and 150 m respectively, and it is mainly used to realize the connection between network devices in the data center. The 40GBASE-SR4 optical module can not only realize the connection between two 40G network devices by using MTP/MPO fiber jumper, but also can be used together with MTP/MPO to LC fiber jumper to realize the connection between 40G network devices and 10G network devices.
The use of 40G SR4 optical modules is so extensive and important. Then, the installation and maintenance of 40G SR4 optical modules is also a link that cannot be underestimated. How to install 40G SR4 optical module? How to maintain it during installation and use? Continue to explain in detail below.
How to install 40G SR4 optical module?
There are 8 steps to install a 40G QSFP+ SR4 optical module. The 8 steps are as follows:
Step 1: Wear the anti-static wrist strap on the correct grounding point on your hand or rack;
Step 2: Take out the QSFP+ optical module from its protective packaging;
Step 3: Check the label on the appearance of the QSFP+ SR4 optical module to confirm that the model of the optical module is correct.
Step 4: Remove the optical hole dust plug of the QSFP+ SR4 optical module and put it aside.
Step 5: Optical Module Installation with Bail Buckle:
A: Align the QSFP+ SR4 optical module vertically with the slot.
B: Align the QSFP+ SR4 optical module with the slot, and carefully slide the QSFP+ SR4 optical module into the slot until the optical module is in full contact with the slot.
Step 6: QSFP+ SR4 Optical Module Installation with Pull Tab:
A: Hold the optical module with the label facing up.
B: Align the QSFP+ SR4 optical module with the slot, and carefully slide the QSFP+ SR4 optical module into the handle until the optical module is in full contact with the slot.
Step 7: Press the exposed part of the QSFP+ SR4 optical module with your thumb, and fully fix the optical module in the slot.
Step 8: Reinstall the dustproof plug into the optical hole of the QSFP+ SR4 optical module until the optical fiber jumper is connected. Do not remove the dustproof plug until the optical fiber jumper is connected.
