What is Fiber Optic Transceiver?
Fiber Optic Transceiver also known as Fiber Optical Transceiver,Optical Module,Optics Module etc. It is a single,packaged device that uses fiber optical technology to transmit and receive data. ‘Transceiver’ is a combination of two words,’transmitter’ and ‘receiver’. In other words,the fiber optic transceiver comprising both a transmitter and a receiver which are combined and share common circuitry or a single housing. It is an important part of optical network eqLog Outuipment that has electronic components to condition and encode/decode data into light pulses and then send them to the other end as electrical signals. To send data as light,it makes use of a light source,such as VSCEL,FP and DFB laser,which is controlled by the electronic parts,and to receive light pulses,such as Pin,APD,it makes use of a photodiode semiconductor.

What is Mode Conditioning Patch Cables?
Mode Conditioning Patch Cables (MCP) is a duplex multi mode patch cord that has a small length of single-mode fiber cable at the start of the transmission leg including a single mode to multi-mode offset fiber connection part. Mode Conditioning Patch Cables are assembled with connectors using 62.5/125um or 50/125um fiber. The calibrated offset reduces phenomena called differential mode dispersion, or DMD, which can cause the transmitting laser pulse to spread out and merge into neighboring pulses creating bit errors in the transmission signal.

What is Power-over-Ethernet (PoE)?
Short for Power over Ethernet, PoE is a standard that allows Ethernet cables to simultaneously transmit data and power using a single network cable. This allows system integrators and network installers to deploy powered devices in locations that lack electrical circuitry. PoE eliminates the expense of installing additional electrical wiring which entails hiring professional electrical installers to ensure that strict conduit regulations are followed. Typical PoE users are businesses adding to their network or adding VoIP phones in buildings where new power lines would be expensive or inconvenient.

Optics Digital Diagnostic Monitoring Interface Tutorial
Digital Diagnostic Monitoring or DDM is also known as Digital Optical Monitoring or DOM. According to SFF-8472,It is an extension of the serial ID interface defined in the GBIC specification, as well as the SFP MSA. Both specifications define a 256-byte memory map in EEPROM that is accessible over a two-wire serial interface at the 8-bit address 1010000X (0xA0). The digital diagnostic monitoring interface makes use of the 8-bit address 1010001X (0xA2), so the originally defined serial ID memory map remains unchanged. The interface is backward compatible with both the GBIC specification and the SFP MSA. Digital Diagnostic Monitoring defines a digital interface allowing the user to access real-time operating parameters including transceiver temperature, supply voltage, transmitter bias current, transmitter output power, and received optical power.

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.
