What is the fiber optic transceiver?
It is a device that uses fiber optic technology to transmit and receive data. Transceiver is a combination of transmitter and receiver. It is used to convert the electrical signals and optical signals.
What is the SFP or SFP+?
SFP, Small Form-Factor Pluggable. Classified by package, SFP and SFP+ are two types of fiber optic transceiver. The main difference is that SFP+ is an updated version that supports higher speeds up to 10Gbps.
What are the applications of fiber optic transceiver?
Fiber optic transceiver is widely found in wired networking applications, including Ethernet switches, routers, firewalls, network interface cards and fiber media converters.
What is the meaning of some abbreviations of transceiver?
LC | Lucent Connector, the interface type, divided into simplex and duplex |
SMF | Single Mode Fiber, the wavelength is 1310nm or 1550nm |
MMF | Multimode Fiber, the wavelength is 850nm |
LRM | Long Reach Multimode |
SR | Short Reach, with several hundred meters |
LR | Long Reach, the transmission distance is 10km |
ER | Extended Reach, the transmission distance is 40km |
ZR | the transmission distance is 80km |
LX | 1.25G SFP, the transmission distance is 10km |
DDM | Digital Diagnostic Monitoring, a technology to make users monitor the real-time parameters of the optical module |
DOM | Digital Optical Monitoring, a function to monitor all aspects of the data of the optical module in real time |
CDR | Clock and Data Recovery, to Keep the signal at the receiving end consistent with the signal at the transmitting end |
What are main parameters of fiber optic transceiver?
Data rate | The number of bits transmitted per second, such as 1.25Gb/s, 10Gb/s |
Transmission distance | The maximum distance over which optical signals can transmit, such as 300m, 10km, 20km |
Wavelength | Represents the wave band used for optical signal transmission, main three wavelengths: 850nm, 1310nm and 1550nm |
