The current branch deployment of ports has become one of the popular ways to build networks, and has driven the development of the parallel optical module market. At present, the commonly used parallel modules are 40G QSFP+ SR4 and 100G QSFP28 SR4, which can be converted into four 10G/25G links for link. This parallel optical module is conducive to multi-link applications, such as the constru...

In this article, ETU-LINK will introduce the 100G QSFP28 and 25G SFP28 cost-effective port branch connection solutions. The following will analyze and compare from the two aspects of saving space and cost. First of all, let's talk about why the cost performance is high, we can judge by comparing the cost. We can assume a scenario with an 8-slot chassis, which is fully equipped with 36 QSFP28 ports...

The role of optical modules in optical communication networks is photoelectric conversion. And they are the core components for photoelectric conversion in optical communication systems. Many engineers and buyers ask: what optical devices are mainly composed of optical modules? What are TOSA and ROSA? What roles do they play in optical transceivers? How do TOSA, ROSA and BOSA work together? This a...

10G SFP+ optical switch has been widely used in data centers and enterprises. In this blog, ETU-LINK lists the connection schemes that accessible 10G SFP+ ports? And under what circumstances is it more appropriate to choose which one. Firstly, if the transmission distance is relatively close, we can consider using ETU 10G DAC cables for transmission. The length specifications of DACs on the market...

This blog ETU-LINK will show you how to identify the wavelength of CWDM optical module through the color of the pull ring. We all know that CWDM has a total of 12 wavelengths, with a full band range of 1270-1610nm, with each wavelength interval of 20nm. The industry divides the entire band into front wave and back wave, with the front wave band of 1270-1450nm and the back wave band of 1470-16...

With the continuous surge of traffic, major operators and data centers began to upgrade the network architecture economically, smoothly and reliably. At present, there are two 100G migration paths, namely 10G to 40G to 100G and 25G to 100G. Next, ETU-LINK will introduce the wiring schemes of these two paths.   1. 10G wiring The 10 Gigabit Ethernet technology defi...
