The SFP light module is the hot plug -in small bag module of the SFP packaging. At this stage, the larger rate can reach 10.3G, and the power socket is LC. The key of the SFP light module is composed of laser generator. SFP classification can be divided into rate classification, wavelength classification and pattern classification of light. The SFP optical module consists of a laser generator (including data signal signal transmitter TOSA and receiver ROSA) and PCB line board IC and external components. The external components consist of cases, base positions, PCBA, bottle plugs, locks, open components and rubber The composition of plug. In order to better and more convenient and convenient, in general, the basic parameters of the module are based on the color of the bottle plug.
The XFP light module and the SFP light module are detailed.
At different rates, the SFP light module is divided into 155m/622m/1.25g/2.125g/4.25g/8g/10g, 155m and 1.25G market sales of the wavelength of the market sales of 850nm/1310nm/1550nm/1530nm/1530nm /1610Nm, 850nm is SFP single -mode fiber, below 500nm, 1310/1550nm is multi -mode fiber, and more than 2km is a multi -mode fiber. Relatively speaking, the price of the wavelength of these three lights is cheaper than the other three.
The plug of the SFP single -mode optical fiber control module is black and gray bottle, the wavelength of light is 850nm, the single -mode specification model is 50/125um or 62.5/125um, and the server bandwidth (optical fiber line information transmission volume) is generally 200MHz to 2GHz. According to the single -mode, the single -mode optical fiber terminal equipment can carry out a transmission of nearly 5 kilometers. The light source is generated by the emitting diode or laser.
The SFP multi-mode optical fiber light module is a dark blue bottle, the wavelength of the light is 1310nm, and the multi-mode specification model is 9-10/125mm. Compared with the single mode, it has the characteristics of endless server bandwidth and no consumption. Multi -mode optical fiber -end machines are mostly used for remote control and transmission, sometimes it can reach 150 to 200 kilometers. Choose LD and spectrals with small LEDs as light sources.
XFP light module.
The XFP light module and the SFP light module are detailed.
The XFP optical module is a standardized packaging of serial communication 10G light collection and sending modules. Following the XFPMSA protocol, it can be used in Sonetoc-192, 10Gbps Gigabit Ethernet, 10Gbps optical fiber lines and G709 connections, and choose LC power sockets. Combined with the following specific standards: 10G optical fiber line line safety exit, 10G Gigabit Ethernet, SONET/OC-192, SDH/STM-64. The key to data communication and telecommunications network data transmission of optical fiber transmission laser welding laser welding.
The XFP module is a hot-plug, occupying PCB line board, occupying a small area, serial communication-serial communication light transceiver. The XFP multi -source protocol (MSA) immediately selects the XFI socket specification model definition of the power installation engineering power socket to complete the SDH light transmission Internet limit. Compared with the 1x9 and SFP modules, XFP has a higher transmission rate and transmission working ability, and also promotes the scope of the use of Gigabit Ethernet to expand to the transmission Internet and wireless LAN.
The XFP optical module is commonly used, including 10Gbps SONET/SDH, optical fiber line safety export, 10G Gigabit Ethernet, SONET/OC-192, SDH/STM-64HE, and other applications, including DWDM connections.
