Industry Dynamic + 2023.11.20

The main purpose of conducting optical module testing is to ensure that the performance of the optical module is reliable, meets the specification requirements, and can work stably in the actual application scenarios, specifically including the following aspects:

Confirming the transmission and reception performance of the optical module: By testing the transmission and reception performance of the optical module, it ensures that it can transmit signals normally and guarantee the quality and reliability of data transmission.

Meet the corresponding standards and specifications: When conducting the procurement and deployment of optical communication system equipment, it is usually necessary to meet the corresponding standards and specifications, and optical modules are no exception. Through testing, optical modules can be examined to see if they meet the relevant standards and specifications to ensure the reliability and stability of optical modules in actual application scenarios.

Troubleshooting problems in the production and manufacturing process: Through testing, problems that may exist in the manufacturing and production process of optical modules can be found, resolved and improved in a timely manner to improve the manufacturing quality and stability of optical modules.

Ensure network operation efficiency and stability: Optical module is one of the key components of optical communication system, and its stability and reliability are crucial to the operation efficiency and stability of the whole network. Through optical module testing, its stability and reliability can be ensured, thus improving network operation efficiency and stability.

Conducting optical module testing is one of the key links to ensure the stable operation of optical communication systems.

For 10G optical modules, the following test programs can generally be used (selected and adjusted according to specific circumstances):

Transmit test: test whether the optical module can normally transmit optical signals, mainly including laser initial operating current, transmit power, center wavelength, spectral width and other parameters test.

Receiving test: test whether the optical module can normally receive optical signals, mainly including receiving sensitivity, BER, threshold current, hardware weakening and other parameter tests.

Overall performance test: Comprehensive test on the transmission and reception performance of the optical module under typical working conditions, mainly including data transmission test and environmental adaptability test.

Compatibility test: test whether the optical module can be compatible with other equipment, including interoperability test of different brands of optical modules, switches, routers, servers and other equipment.

Durability test: Test the stability and reliability of the optical module during long-term use, mainly including temperature cycling test, vibration impact test, hot and humid environment test.

What are the 10G optical module test equipment? The commonly used equipment is as follows:

Light source: such as LD (laser diode), LED (light-emitting diode), etc., which is used to generate optical signals for emission testing.

Optical power meter: used to measure the optical power transmitted and received by the optical module.

Analog Signal Source: Used to generate analog data for data transmission testing and BER testing.

Bit Error Rate Analyzer (BERT): used to test the bit error performance of data transmitted by optical modules.
