40G SR4 Optical Module Introduction
40G QSFP SR4 optical modules are high-speed, high-density transceiver modules that are commonly used in data center applications. These modules transmit and receive data over very short distances at speeds of up to 40 Gbps. 40G QSFP SR4 optical modules are typically used in short-reach applications.The 40GBASE-SR4 optical module (ie QSFP-40G-SR4 optical module) conforms to the IEEE 802.3ba 40GBASE-SR4 standard and adopts the MPO/MTP interface design. When used with OM3 fiber, the maximum transmission distance can reach 300m, and when used with OM4 fiber The transmission distance can reach 400m.
The 40G SR4 optical module has 4 independent optical signal transmission and reception channels, each channel can support 10Gbps data transmission, often used with 12-core MTP trunk fiber jumper, 4-core for transmission, 4-core for for receiving, while the middle 4 cores are idle. In addition, 4x10G transmission can also be achieved by connecting an 8-core MTP-LC breakout cable.
How to maintain the 40G SR4 optical module?
For the maintenance of 40G QSFP optical modules, you can refer to the following points:
Do the following during use:
1) Handle with care;
2) Positive optical port insertion
3) Avoid long-term exposure and use dust caps;
In the daily maintenance, pay attention to two aspects:
1) Optical port protection
2) ESD protection
Specific precautions for optical port protection:
1) Select a fiber optic connector that meets network access standards;
2) The optical fiber connector must have a sealing cap. When not in use, cover the sealing cap to avoid the pollution of the optical fiber connector and the secondary pollution of the optical port of the optical module; the sealing cap should be stored in a dust-proof and clean place when not in use;
3) The insertion of the optical fiber connector is horizontally aligned with the optical port to avoid scratches on the end face and sleeve;
4) Avoid prolonged exposure of the optical port of the optical module, cover the optical port plug when not in use; store the optical port plug in a dust-proof and clean place when not in use;
5) Keep the end face of the fiber optic connector clean
ESD protection precautions:
1) Keep the humidity of the environment at 30~75%RH;
2) When operating the optical module, do electrostatic protection work (such as: using an electrostatic ring or releasing static electricity by touching the case in advance), touching the optical module housing, and avoiding touching the optical module PIN pins;
3) The related equipment used is grounded at the common grounding point grounded in parallel to ensure the shortest grounding path and the smallest grounding loop, and cannot be grounded in series. The design method of using an external cable to connect the grounding loop should be avoided;
4) When packaging and turnover, use anti-static packaging and anti-static turnover boxes/cars;
5) It is forbidden to perform live plugging and unplugging of non-hot-pluggable equipment;
6) Avoid using a multimeter pen to directly detect static-sensitive pins.
