How to choose Industrial grade optical modules？
1、Usually the transmission distance of multimode industrial-grade optical module is shorter than it of single-mode industrial-grade optical module, the price is also cheaper. So when choose or buy the industrial-grade optical module, we should accord to the actual situation and decide. If need to short distance transmission, you can choose the multimode industrial-grade optical module, if need to long distance transmission, you have to choose single-mode industrial-grade optical module.
2、Whether the hardware of the industrial-grade optical module meets the standard, the electrical components and shell of the industrial-grade optical module shall be designed with hardened parts, and the chips and lasers of the industrial-grade optical module shall meet the grade requirements of industrial temperature (-40℃~85℃).

FAQ
1、Question：Is it necessary to clean a transceiver's optical connector?
Answer：Dust and contamination can accumulate on transceiver's connectors and cause problems such as reducing the optic launch power. To ensure better connection, HTF strongly recommends cleaning both connectors each time you disconnect and reconnect them.
2、Question：What kinds of custom choices are offered in HTF?
Answer：As for customized transceivers, HTF offers regular custom choices such as compatibility, transmission distance, operating temperature, label pattern, label colors and etc. What's more, HTF welcomes any inquiry for customized products and solutions for all need and specifications
