What is HCF hollow core fiber?
Hollow core fiber (HCF) is a special fiber structure whose core area is hollow (usually air or vacuum) instead of the solid glass/plastic medium of traditional optical fiber. The light in hollow core fiber mainly propagates through the air core, rather than relying on the principle of total reflection, so it can reduce the attenuation of […]

MPO/MTP Cable Advantages And Application
With high speed data transmission demand in data centers, traditional fibre patch cords cannot meet the connection requirements, now we should need high density and better store more data in a limited space. However, the normal connector SC FC LC ST can not meet such request, so there were MTRJ, E2000 or MU connectors, and during these 10 years, MPO/MTP […]
How to choose good quality MPO MTP patch cable?
With the increasing demand for high-speed transmission and high-density wiring such as big data, data centers, AI artificial intelligence and computing centers, 5G, etc., the application of MTP cable has been doubling in recent years. The quality of MPO fiber jumpers determines the stability and sustainability of the entire data center network. Therefore, how to choose good […]
What are the types of optical multiplexers?
WDM (Wavelength Division Multiplexing) technology is the preferred solution for 5G fronthaul networks. According to different wavelengths, it can be divided into DWDM, CWDM, FWDM, MWDM and LWDM. Among them, CWDM and DWDM are the most common. First, let’s take a brief look at the main optical wavelengths. The CWDM wavelength range specified by ITU (ITU-T […]
Basic Knowledge Of wavelength Division Multiplexing WDM
What is WDM and how it works? WDM (wavelength division multiplexing) is a technique where two or more optical carrier signals of different wavelengths (carrying various information) are combined at the transmitting end through a combiner (multiplexer) and connected to the same optical fiber for transmission. At the receiving end, the optical signals of various […]
What is the difference between CWDM optical transceiver and ordinary optical transceiver?
With the development of the optical communication industry and the accelerated promotion of 5G, related peripheral industries are also growing rapidly, and the optical transceivers industry is no exception. In addition to our common optical transceivers, there are also WDM optical transceivers. Today, we will talk about the difference between ordinary optical transceivers and CWDM […]
The difference, MPO male connector VS MPO female connector
The optical modules we usually use are generally LC interfaces or MPO interfaces. Optical modules with different interfaces need to be connected with fiber patch cables of corresponding interfaces. LC interfaces are found in optical transcievers of all speeds, while MPO interfaces are usually found in optical modules of high speeds. MPO/MTP connector is one […]
Why 24 fiber MTP MPO patch cord or MTP patch cable don’t use ribbon cable?
During the factory production or use of MTP MPO patch cable, we often find that bundled cables are used instead of ribbon cables. Why is this? Below you will find answer in detail from the force and loss of optical cables during the production, transportation and use of optical cables. Ribbon cable is with ribbon […]
Transmission cable form DAC, AEC, AOC, ACC brief introduction
Today, the communications industry is in high competition, everyone expects to gain a competitive advantage, whether in terms of performance, efficiency or cost. While many data center renovations focus on network adapter and switch configurations, there is an extremely basic, but equally effective way to improve deployed data centers, which is to rethink interconnect cables. There are […]
What are the differences between GBIC, SFP, SFP+, SFP28, QSFP, QSFP+, and QSFP28?
GBIC, SFP, SFP+, SFP28, QSFP, QSFP+, QSFP28 are all packaging methods for optical transceiver, they are different transmission rates and are the main ways to distinguish optical modules. Among them, SFP, SFP+, SFP28 have the same size, and QSFP+, QSFP28 have the same size. These methods are the main types of optical modules for DAC Cable and AOC […]
