AQ6370D Spectrum Analyzer: Accurate Measurements with DWDM System

2024.07.22
With the rapid advancement of 5G networks, optical communication technology has ushered in unprecedented changes. Dense wavelength division multiplexing (DWDM) systems have become the core of modern fiber optic communication networks due to their efficient data transmission capability and spectrum utilization. However, the dense channel distribution and high-speed data transmission in DWDM systems place higher requirements on the optical spectrum analyzer (OSA).

What is the difference between SR, LR, LRM, ER and ZR in 10G optical modules?

2024.07.09
SR, LR, LRM, ER and ZR are the more common module types in the 10GIEEE standard, but what is the difference between 10g SR, LR, LRM, ER and ZR? First we need to know what they represent. In fiber optic communication, SR, LR, LRM, ER and ZR are a kind of distance terminology in 10G optical module transmission, SR means short distance, LR means long distance, LRM means length extended multipoint mode, ER means ultra-long distance, and ZR means the longest distance.

N7779C keysight Tunable Laser Source Description

2024.03.06
The new N7779C Base Series tunable laser source, like the other new N777xC models, is ideal for cost-effective testing of broadband optical devices because of its ability to step quickly to discrete wavelengths with resolutions up to 0.1 pm and typical wavelength repeatability of ±3 pm. Short wavelength setup times (e.g., 300 ms) enable fast step scanning. Like other laser sources in the N777xC family, it delivers peak output power in excess of +12 dBm and low spontaneous emission levels. With power stability of ±0.01 dB per hour, it can also be used as a static local oscillator with a wide tuning range for receiver testing or transmission experiments.

Reasons and advantages of switching to PAM-4 signalling instead of NRZ for 400G Ethernet

Currently, 100G Ethernet has become the dominant standard in data centres, but with the emergence of new technologies such as 5G, IoT and AI, 100G Ethernet can no longer meet future demands and 400G Ethernet has become the new target. To achieve higher bit rates at the same baud rate, it is necessary to use higher-order modulation, such as PAM-4 (Pulse Amplitude Modulation, 4th order) signalling, which carries two bits of information in each symbol to achieve twice the bit rate.

10G PON and 25G PON: Next Generation Technologies for Passive Optical Networks

Passive optical network (PON) is a fibre-optic access technology that distributes fibre-optic signals to multiple users through a passive splitter, achieving the goal of fibre-to-the-home (FTTH).PON technology has the advantages of high transmission rate, wide coverage, low cost, energy saving and environmental protection, and it has become one of the mainstream technologies for broadband access. With the increasing demand of users for high-speed broadband access, PON technology is also developing continuously, from the initial GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network), to the later 10G PON (10 Gigabit Passive Optical Network), and then to the latest 25G PON (25 Gigabit Passive Optical Network), the downlink rate of the PON technology has been increased by 25 times, reaching the level of 25Gbps. the level of 25 Gbps. This article will introduce the key technologies of 10G PON and 25G PON, as well as their advantages and application scenarios.
