Why Choose a 40-Channel DWDM Multiplexer/Multiplexer
Mar 04 , 2022
DWDM (Dense Wavelength Division Multiplexing) is an ideal optical multiplexing technology for long-distance data transmission, which can put multiple channel information using a single wavelength on the same fiber and greatly improve the transmission capacity of optical networks. At present, DWDM technology is widely used in telecommunication networks and has become the choice of many telecommunic...

What is Dense Wavelength Division Multiplexing
Mar 08 , 2022
The so-called dense is relative to the interval between two adjacent wavelengths. In the past, the wavelength interval of the wavelength division multiplexing system was several tens of nanometers. Now the wavelength interval is only 02 to 1.2 nm. The spectrum allocation is shown in Figure 2-1. DWDM technology is actually a specific form of wavelength division multiplexing. Generally, the waveleng...

Introduction of 100G DWDM QSFP28 CS Connector PAM4 Transceiver
Jun 09 , 2022
What is PAM4? PAM4 is a technology that uses four different signal levels for signal transmission, and each symbol period represents 2 bits of logical information (0, 1, 2, 3). By transmitting two bits in one symbol slot, PAM4 cuts the signal bandwidth in half. With half the bandwidth, PAM4 can achieve 50Gb/s data transfer in a 25Gb/s electrical tolerance environment. Additionally, PAM4 minimizes ...

The reason why wdm network is so popular
Aug 17 , 2022
With the adjustment and improvement of various traffic routes, the distance between everyone is also farther and farther. Voice, video and data networks are becoming more complex as the demand for more bandwidth and faster transfer rates increases. To meet these demands, network administrators rely more on fiber optics. Many suppliers, corporate companies and government entities are turning to fib...

What is the difference between CWDM technology and DWDM technology?
Sep 16 , 2022
In WDM technology, there are CWDM coarse wavelength division multiplexing technology and DWDM dense wavelength division multiplexing technology. Literally, these two technologies have different degrees of density in a band, but there are still many practical technologies and applications. difference. ①The wavelength interval is different The CWDM carrier channel spacing is wider and each band is 2...

WDM passive wavelength division 5G fronthaul solution
Sep 27 , 2022
The 5G fronthaul passive WDM system is mainly used to solve the problem of long-distance optical fiber between DU-AAU and lack of transmission optical fiber resources in the C-RAN architecture. The optical module replaces the original gray optical module on the wireless device, thereby providing business optical signals of different wavelengths. The passive wavelength division multiplexers on both...

Why 400G QSFP-DD is more popular than 400G OSFP and 400G CFP8
Oct 14 , 2022
At present, the main products of 400G transceivers are QSFP-DD, OSFP and CFP8. This article introduces: Why 400G QSFP-DD is more popular than 400G OSFP and 400G CFP8 1: QSFP-DD provides maximum port density. This makes QSFP-DD more attractive than OSFP form factor modules and larger CFP8 modules. 2: The power consumption (the maximum power that the module can dissipate without damaging the interna...

How to solve when the optical module fails?
Nov 11 , 2022
During the use of the optical transceiver module, various problems will inevitably occur. The following summarizes the main reasons and solutions in the event of failure. Matters needing attention before use 1. Do not connect optical modules with different wavelengths. Due to the different transmission loss and dispersion in the fiber, the transmission distance corresponding to different wavelengt...
