- An increase in temperature will cause the wavelength to shift red, and a decrease in temperature will cause the wavelength to shift blue.
The effect of optical fiber on wavelength:
Fiber dispersion:
- Light of different wavelengths will produce different dispersion effects when propagating in optical fibers.
- This will broaden the light pulse and affect the stability of the wavelength.
Microbending loss:

Wavelength selection of J9150D in different applications
Let me combine the actual needs of optical fiber communication systems and analyze the wavelength selection strategies of J9150D optical modules in different application scenarios.
Wavelength requirements for optical fiber communication systems:
Single-mode optical fiber transmission:
- The most commonly used transmission wavelengths of single-mode fiber are 1310nm and 1550nm.
- These two wavelength bands have lower fiber loss and dispersion.
Wavelength division multiplexing technology:
- Wavelength-division multiplexing (WDM) technology can multiplex multiple signals of different wavelengths on a single optical fiber.
- This requires that the light sources of each channel have different and stable center wavelengths.
Application scenario requirements:
- Different application environments may have specific requirements for light wavelengths.
- Such as metro networks, long-distance trunk networks, etc. usually require a wavelength of 1550nm.
Wavelength selection strategies for J9150D in different scenarios:
Single-mode optical fiber transmission scenario:
- J9150D uses 1310nm wavelength, which matches the optimal transmission wavelength of single-mode fiber.
- This provides low-loss, low-dispersion, high-speed 10GbE fiber transmission performance.
WDM system application:
- The 1310nm wavelength of J9150D can be multiplexed with other wavelength channels such as 1550nm.
- Coupled with DWDM/CWDM technology to expand the transmission capacity of optical fiber.
metro/trunk network application:
- If the application scenario requires a wavelength of 1550nm, J9150D may not be able to directly meet the requirement.
- At this time, you need to use the 1550nm version of the SFP+ optical module or use wavelength conversion equipment.
In short, the J9150D optical module uses 1310nm single-mode wavelength, which is very suitable for standard single-mode fiber transmission applications. However, in some special WDM or metro network scenarios, it may be necessary to select an appropriate wavelength version optical module according to actual needs, or to adapt using wavelength conversion technology.
