In addition to the most common commercial grade, we can also see extended-grade and industrial-grade options when purchasing optical modules, depending on the operating temperature. Why do optical modules need to be divided into so many temperature levels, and what are the differences between them? As one of the most important parameters of an optical module, the operating temperature can affect other parameters. When the ambient temperature of an optical module changes, other parameters such as its operating current will also change, which will affect its normal transmission. Extended-grade and industrial-grade optical modules are designed to solve this problem. The most common optical modules are C-TEMP, and their normal operating temperature ranges from 0 to +70\u2103. E-Temp ranges from -20\u2103 to +85\u2103. The I-Temp works at temperatures ranging from -40\u2103 to +85\u2103, enabling it to work in extremely high or ultra-low temperatures. In addition, industrial optical modules must be designed with scene-hardened components in terms of electrical components and enclosures to ensure the service life of the modules.<\/p>\n

Commercial grade optical modules are 0\u2103\uff5e70\u2103, the extended grade is -20\u2103\uff5e+85\u2103, industrial grade optical modules are -40\u2103\uff5e85\u2103, the same as can support working temperature.<\/p>\n

Different testing methods<\/b><\/strong><\/p>\n

Commercial-grade optical modules only need to be tested for normal temperature aging, while industrial-grade optical modules need to be tested for high and low-temperature aging.<\/p>\n

Price difference<\/b><\/strong><\/p>\n

Due to the physical cooling and temperature compensation of industrial optical modules, the raw material cost and manufacturing cost increase. Therefore, when the transmission rate and wavelength are the same, the price of industrial optical modules is usually higher than that of commercial optical modules, as shown in the following table:<\/p>\n

Different application scenarios<\/b><\/strong><\/p>\n

Commercial optical modules:\u00a0It is the most common and widely used product in the market. It is generally used in network environments such as enterprise networks, data centers, and computer rooms.<\/p>\n

Extended optical modules: It is used in relatively harsh environments with large temperature differences, such as remote mountain areas and tunnels in the wild.<\/p>\n

Industrial optical modules can withstand lower temperatures than extended-grade optical modules. Industrial optical modules are generally used with industrial-grade Ethernet switches and are used in industrial Ethernet applications in factory automation, railway and intelligent transportation systems (ITS), power facility substations, Marine, oil, gas, mining, and other industries. Industrial optical modules can be durable and have the stable transmission in harsh working environments.<\/p>\n

Hardware Compliance<\/b><\/strong><\/p>\n

The chips and lasers used in industrial optical modules must be made of products that meet industrial temperature levels and require high-temperature heating when conducting tests.<\/p>\n

Temperature compensation<\/b><\/strong><\/p>\n

When the industrial optical module<\/span><\/a> operates at a low temperature below zero, in order to ensure the stable transmission power of the optical module, temperature compensation must be carried out to ensure the normal operation of the optical module at a low temperature.<\/p>\n

Physical cooling<\/b><\/strong><\/p>\n

The industrial optical module must have a self-cooling function to meet stable operation at high temperatures. The heat generated by the laser is dispersed as soon as possible by using thermal silica gel for physical cooling.<\/p>\n
