For many broadband operators, access network evolution is not defined by a single technology leap but by a series of incremental, carefully measured decisions. Existing DOCSIS infrastructure, established operational processes, and large installed CPE bases continue to influence network planning stra...
As hybrid fiber-coaxial (HFC) networks evolve toward higher bandwidth and faster data rates, components that support extended frequency ranges are becoming increasingly important. The move from 1.2 GHz to 1.8 GHz spectrum marks a significant upgrade in broadband infrastructure, enabling operators to...
Fiber optic technology has become the backbone of today’s video and broadband distribution. When it comes to CATV and satellite TV networks, a CATV+IF optical transmitter and receiver system provides a powerful way to deliver high-quality signals over long distances, while keeping performance...
In many communication systems, RF signals need to travel tens of kilometers. At lower frequencies coaxial cables are still usable, but once you move into the multi-GHz range, loss and interference quickly become unacceptable.
RFoF (Radio over Fiber) addresses this by directly modulating...
Building a clean, reliable video overlay on GPON or XGS-PON starts with choosing the right CATV optical receiver. The goal is simple: preserve picture quality while keeping your fiber resources and power budget in check. A good approach is to map your performance targets (noise, linearity, output le...
Wireless networks are the backbone of modern communication, supporting everything from mobile phones to IoT devices. One crucial component that ensures optimal wireless network performance is the Low Noise Amplifier (LNA). LNAs are designed to amplify weak signals without adding significant noise, w...
In today’s digital era, where viewers expect crystal-clear visuals and uninterrupted connectivity, ensuring the reliability of cable TV (CATV) signal transmission is more critical than ever. One of the key technologies driving this reliability is MMIC – Monolithic Microwave Integrated C...
The 1.8GHz Forward Amplifier Module: Bridging Signals and Connecting the World
In today’s world, where seamless connectivity is expected everywhere, from remote villages to bustling cities, the reliability of communication systems is crucial. Whether it's a satellite transmitting data t...
As the demand for high-quality video and internet services continues to grow, CATV networks are increasingly relying on advanced optical receiver modules to provide superior performance. These optical receiver modules are integral to ensuring that cable television (CATV) systems, fiber-to-the-home (...
Fiber to the Home (FTTH) is a communication technology that involves the transmission of signals directly to users' homes via optical fibers. Compared to traditional copper cable connections, FTTH offers higher bandwidth, faster transmission speeds, and longer transmission distances. In recent years...
At present, an effective method to solve the increasing bandwidth of information transmission is to use CWDM equipment and DWDM equipment, but they are different in many aspects.
1. Channel spacing between CWDM equipment and DWDM equipment
Channel spacing is defined as the difference between...
1. Larger scale and scope
Compared with the basic equipment required by traditional LANs, passive optical LANs relatively reduce the number of cables and devices in network deployment. In the traditional LAN architecture, copper cables such as Cat6 are mainly used for data transmission, while the pa...
