Gigabit Passive Optical Network

 

It is a type of high-speed network standard for Internet access, mainly used for broadband services over optical fiber. Here are the details of GPON and its main features:

1. Network Structure: GPON is based on point-to-multipoint architecture, which means that a single fiber optic cable can serve multiple locations using passive optical splitters. This is in contrast to the point-to-point model, where each location requires its own fiber optic cable.

2. OLT and ONT/ONU: OLT (Optical Line Terminal): This is a device located at the service provider's headquarters. It transmits data to multiple users and also collects data from users. ONT (Optical Network Terminal) or ONU (Optical Network Unit): This is a device located at the customer's premises. It receives data sent from the OLT. The terms ONT and ONU are sometimes used interchangeably, but ONT is usually customer facing and ONU can refer to a larger device that serves multiple customers in some situations.

3. Speed ​​and Efficiency: GPON offers asymmetric bandwidth with downstream rates of up to 2.5 Gbit/s and upstream rates of up to 1.25 Gbit/s. However, there are advancements and new standards that can provide even higher rates. The use of passive splitters in the network eliminates the need for power in the distribution network, reducing maintenance costs and improving reliability.

4. Wavelengths: GPON uses wavelength division multiplexing (WDM), which allows multiple signals with different wavelengths (colors) of light to be transmitted over a single optical fiber. Typically, two wavelengths are used, one for downstream data and one for upstream data.

The best HP laptops with folding screens

 

HP Specter Foldable Computer

Considered as a three-in-one PC of hp Brand, this new laptop is based on a 17-inch OLED display that can be used as a 12-inch laptop, a 17-inch tablet, or a 17-inch all-in-one desktop. And when used as a laptop, you have two ways to set up the Bluetooth keyboard. You can have the keyboard rest completely on the bottom half of the screen, mimicking a 12-inch clamshell laptop, or you can tilt the keyboard slightly to extend the screen across the screen for more screen space.

 

How we test laptops ?

The laptop review process has two parts: Performance testing under controlled conditions in CNET's lab and hands-on experience by our reviewers. This includes evaluating the aesthetics, ergonomics and performance of the device in relation to its cost. The final decision of the investigation is a combination of objective and judgment. We test all the laptops with benchmarks, including Primate Labs Geekbench 5 and 6, Cinebench R23, PCMark 10, various 3DMark benchmarks (depending on what the laptop can run), UL Procyon Photo and Video (where supported), and our own battery life tests. If the laptop is for gaming, we will also run the Guardians of the Galaxy benchmarks, The Rift Breaker (CPU and GPU), and Shadow of the Tomb Raider benchmarks. For practice, the examiner uses it for his work during the examination period, checking how the structure, features (such as the screen, camera and speaker) and the software of the manufacturer work as well. We also value their services due to their value and any promotion or agreement made by the manufacturer for their price. The list of benchmarking software and comparison criteria we use grows over time as the devices we test evolve.
