X2 Optical Module Introduction
X2 is a standardized package of the 10G optical transponders. X2 are available for both versions 10G Ethernet and 10G Fibre Channel. X2 optical transponder is only applied to the data communication optical fiber connection (not used in the telecommunications transmission network), and their size is smaller than XENPAK optical transponder. Electrical interface of board is standardized, be known as XAUI (4X3.125Gb / s).

CFP Optical Module Overview
Optical modules are not standardized by any official body, but are in Multi-Source Agreements (MSAs). One agreement that supports 40 and 100GE is the C Form-factor Pluggable (CFP) MSA, which was adopted for distances of 100+ meters. The C stands for the Latin word for 100, centum, since the standard was primarily developed for 100GE.

What does Electrostatic Discharge Mean?
Electrostatic discharge (ESD) is a swift discharge of electric current between two objects with different charges and different numbers of electrons. This exchange of electrons creates a large electromagnetic field buildup, resulting in ESD.

The Develop Trends of Next Generation CFP Transceivers
The current generation of optical modules is large because of heat dissipation issues due to high power consumption. For example, the CFP is rated for up to 24 watts of power dissipation but also needs to have a range of high density electrical connectors to connect to the baseboard. I take this to mean big, hot and heavy.

What is 100G CFP?

With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

What is CWDM SFP? Which areas does it mainly apply to?

1. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

What is AOC and DAC?

AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.

What is DWDM SFP? What areas does it mainly apply to?

Dense Wavelength Division Multiplexing (DWDM) technology is capable of transmitting data in an optical fiber using bit wavelength parallel transmission or string line transmission using the wavelength of the laser.It is widely used in different fields of communication networks, including long-distance backbone networks, metropolitan area networks (MANs), residential access networks, and local area networks (LANs).The DWDM optical module is the optical module that uses this technology, so the DWDM optical module has high bandwidth and long-distance transmission characteristics.
