The Characteristics Of Optical Fiber Card
Fiber-optic network card, refers to the Fiber Channel network in the HBA card. Scientific name. The transport protocol is a Fiber Channel protocol and is typically connected to a Fiber Channel switch through a fiber optic cable. The interface type is divided into optical port and electrical port. Optical interface is generally through the fiber optic cable for data transmission, the interface module is generally SFP (transmission rate 2Gb / s) and GBIC (1Gb / s), the corresponding interface for the SC and LC. The interface type of the electrical interface is generally DB9 pin or HSSDC.

SFP + For Telecommunications Data Communications Applications
SFP + can be easily understood as an upgraded version of GBIC. The SFP module (which is half the size of the GBIC module and can be configured with more than twice the number of ports on the same panel. Since the SFP module is basically the same as the GBIC function, SFP+ it is also known by some switch manufacturers as miniaturized GBIC -GBIC.) The SFP module compresses the size and power consumption by placing CDR and electro-dispersion compensation outside the module for optical communication applications in telecommunications and data communications.SFP connection network equipment such as switches, routers and other devices Motherboards and fiber or UTP cables. SFP + is an industry specification supported by some fiber optic device providers.

Can you really distinguish optical module and fiber media converter？
In the field of optical communications, there are many devices with similar functions. For example, optical modules and fiber media converter are equipment for photoelectric conversion, and sometimes they have different names. Optical module is also known as optoelectronic module while fiber media converter is called photoelectric converter. Can you distinguish the differences between them?

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.
