What's the difference between SFP-10G-SR and SFP-10G-LR?
2019-08-31
If we want to understand the main differences between SFP-10G-SR and SFP-10G-LR, we need to know what SFP-10G-SR and SFP-10G-LR are.
SFP-10G-SR in "SR" "meaning (short range),
Wavelength of 850, belonging to the short wavelength, is a multi-die module
Transmission distance of 2 ~ 300m,
The advantages of this product is: the lowest cost, lowest power consumption and smallest fiber optic modules, etc.
SFP-0G-LR in the "LR" refers to the Long Range
The wavelength is 1310nm, which belongs to long wave and is a single mode module.
The transmission distance is 2m to 10km and the maximum distance is 25km.
Features of SFP-10G-LR: miniaturization, low power consumption and long transmission distance
Combined with the above product description, Fiberland Co., Ltd. will compare the differences between the two to facilitate the choice of customers.
1. Different transmission distances
The SFP-10G-SR is used for short-distance transmission. Its wavelength is 850, the distance is 2~300m, and the farthest transmission is 300m.
The SFP-10G-LR optical module is used for long-distance transmission, the wavelength is: 1310nm, the transmission distance is 2~10km, and the maximum transmission limit is 25km.
But they have a common characteristic is not able to support the FCOE link path. We need to choose the right product according to the different transmission requirements
2. The SFP-10G-SR and SFP-10G-LR lasers are different.
The most common is laser optical communications lasers FP and DFB lasers.
* SFP-10G-SR uses VCSEL, 850 wavelength laser, emitting optical power between -6~-1dBm, sensitivity <-11.1dBm
* The SFP-10G-LR uses a laser that is DFB with a wavelength of 1310 nm. The transmitted optical power is -8.2~0.5dBm and the sensitivity is <-14.4dBm.
3. The cost budgets of SFP-10G-SR and SFP-10G-LR are different.
SFP-10G-SR price lower than the SFP-10G-LR price. Because the SFP-10G-LR optical module has a higher cost than the VCSEL laser due to the built-in DFB laser, the performance of the DFB is better.
In summary, we should purchase the optical module in combination with the transmission distance and performance. If you have any demand for the product, please feel free to consult Fiberland company。

012019-10With 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.

012019-101. 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.

012019-10AOC 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.
