Optical transceiver is a small product, it seems simple. In fact, it is assembly completed after more than 10 processes, but still can’t be sold. Because the product need to be strictly testing before shipment, including parameter testing, aging testing, distance testing (fiber testing) and switch testing. We've had a detailed explanation of the tests except switching testing, today we're going to...

Optical transceivers are highly temperature-sensitive photoelectric devices. Ambient and internal operating temperature directly change laser bias current, transmit/receive optical power, receiver sensitivity and signal eye quality. This article explains temperature classification of optical modules, root causes of abnormal temperature, and specific performance damage caused by overheating or ultr...

The PON optical transceiver is a high performance optical module for the PON system, also known as the PON module, conforms to the ITU-T G.984.2 standard and the MSA. It uses different wavelengths to send and receive signals between the OLT (optical line terminal) and the ONT (optical network terminal). Classification of PON optical modules: 1. According to the package type: SFF/SFP/SFP+ and XFP o...

Energy saving and cost are two important factors that need to be considered when deploying data centers. The price of 40G optical module and 100G optical module is too high and the power consumption is too large, and the speed of 10G optical module can not meet the demand of network. Therefore, 25G SFP28 optical module was born in this case, just to make up for the deficiency between the them, gre...
