5G has greatly improved the requirements of key performance indicators, which provides a good market opportunity for the large-scale application of new types of optical devices. But on the other hand, operators have faster and higher requirements for the return cycle of network construction investment. The market environment requires "just right" optical devices, that is, an end-to-end design with moderate redundancy and relatively low...

What is ethernet standard The prototype topology of Ethernet was proposed by Xerox in 1973 and realized in the laboratory, with a speed of only 2.94Mbps. In 1980, Xerox and DEC, Intel jointly published the first version of the 10Mbps Ethernet standard DIX V1, the famous Blue Book. In 1982, DIX V2 was officially announced. On this basis, the Institute of Electrical and Electronics...

The exponential growth of data is one major reason why the global high-performance computing market has thrived. The rapid application and adoption rate for Internet technology, such as intelligent terminals or cloud servers in data centers that store information on behalf of users across different locations requires powerful processing power to efficiently prepare queries against large volumes without losing too much time when comparing...

The traditional single-channel 10 Gb/s or 25 Gb/s rate optical module adopts SFP (Small Form-factor Pluggable, small form factor pluggable) package shell, the size is 56.5 mm × 13.4 mm × 8.5 mm, the electronic chip and TO (Through-hole) packaged light emitting and receiving components are welded to the PCB board to form a photoelectric conversion module with transceiver function. The 100 Gb/s optical...

At present, the optical transmission network generally adopts the non-return-to-zero (NRZ) code transmission method, but when the transmission rate exceeds 28Gbit/s, the system will have strict requirements on the time margin of the transmission link and the transceiver chip, and the high-bandwidth signal will be transmitted in the channel. The losses in the area also significantly increased. This requires us to change the selection...

In recent years, the use of optical transceivers has exploded. This is largely due to the ever-growing demand for bandwidth. Optical transceivers are used to connect different types of optical fiber, and they come in a variety of different forms. In this blog post, we will be discussing bidirectional SFP transceivers. We will start by defining what a bidi transceiver is, and then we...
