The meaning of each field is as follows:
XXXX indicates the speed of the optical module, such as 100 and 1000.
YY means transmission distance:
SX stands for short distance
LX stands for long distance
LH stands for extra long distance.
T stands for electrical module.
Zzzz stands for interface fiber type.
MMF stands for multi-mode.
SMF stands for single mode
The transceiver type indicates the type of optical fiber connector, such as SC and LC.
The wavelength (nm) indicates the central wavelength of the laser beam transmitted by the optical module, with the unit of nm, and generally has the following values: 850 nm, 1300 nm, 13 10 nm, 1550 nm.
Transmission distance (xx) indicates transmission distance and transmission medium, as well as transmission distance. For a single-mode module, xx is displayed as km, while for other modules, xx is displayed as m. When the module supports multiple transmission media, the transmission distance values are separated by commas. The parentheses after the distance value contain the corresponding "transmission medium".
Transmission media are divided into the following categories:
9um: means 9/ 125um single-mode fiber (the PVC sheath of single-mode fiber is yellow, and the wavelength is generally 13 10nm or 1550nm).
50um: 50/ 125um multimode fiber (the PVC sheath of multimode fiber is orange, and the wavelength is generally 850nm or 1300nm).
62.5um: refers to 62.5/ 125um multimode fiber (the PVC sheath of multimode fiber is orange, and the wavelength is generally 850nm or 1300nm).
TP: Indicates whether the twisted-pair digital diagnosis monitoring supports the digital diagnosis function. The digital diagnosis function can display the temperature, voltage, received optical power and emitted optical power of the optical module. The supplier name indicates the manufacturer name of the module or the customized manufacturer name. The order name indicates the external model of the module.
At present, the famous enterprises are as follows:
F-tone Networks (the main foundries of BeiYitong, Huasan, Huawei and Cisco, with excellent compatibility and good cost performance), Finisar (the largest, with acceptable shipments), JDSU O Claro (merged with Opnext 12), Avago (formerly Agilent Optical Devices Division), Neophotonic (Xinfeitong) and Source. Mitsuibish Sumimoto (Sumitomo), Truelight (Halo), Luxnet (Hua Xingguang), Elaser (Lianjun), PCL (Zhong Da), Accelink (WTD), Hisense ... China enterprises pay more and more attention to the resource accumulation of the upstream chip industry, and in the near future, China enterprises will also become aircraft carriers such as JDSU. Generally, most of the goods are taken from Yi Bei Fiber Union, and their home is very compatible and cost-effective. Unfortunately, it's not as large as Finisar.
