As we all know, Optical transceivers support DDM functions, which enable real-time monitoring of modules' parameters. And the DDM information, we can read via switch equipment, simple network management protocol(SNMP). 1.The Useful DDM Function on Optical Modules DDM is a function available on optical transceivers, including SFP, SFP+, XFP and GBIC, and is also known as digital optical monitoring(...

DWDM (dense wavelength division multiplexing) is the preferred technology in today's optical fiber applications, but the price is relatively expensive. In comparison, CWDM (sparse wavelength division multiplexing) is a low-cost WDM transmission technology for the access layer of man. Now ETU-Link will introduce 10g SFP+ CWDM / DWDM optical module. 10G SFP+ CWDM optical module: 10G SFP+ CWDM optica...

SFP, SFP+, SFP28, QSFP+ and QSFP28 are the packaging types of optical modules. These hot-swappable optical modules can be used to connect network switches and other network devices (such as servers, etc.) for data transmission. Before clarifying the difference between these package types, you need to understand what the SFP, SFP+, SFP28, QSFP and QSFP28 packages are. Next ETU-LINK w...

In this blog, ETU-LINK will talk about 4G base stations and common types of optical modules. The base station can be divided into two modules: the RRU for transmitting signals and the BBU for processing signals. The BBU is small and exquisite, with low power consumption, while the RRU is large and has high power consumption. Because the base station is divided into two parts to work sepa...
