Working Wavelength:Single mode SFP modules operate at 1310nm and 1550nm wavelengths.
These wavelengths allow for efficient transmission over single mode fiber.
Color Coding:Single mode SFP modules are typically color-coded with bale clasps and arrows in blue, yellow, or purple.
Blue indicates the 1310nm module, yellow represents the 1550nm module, and purple corresponds to the 1490nm module.
Transmitter Types:Single mode SFPs use edge-emitting lasers (such as Fabry–Pérot, DFB, and DBR lasers) for different reach distances.
These lasers require a hermetic package for stable single mode operation and higher emission power.
Edge-emitting lasers are more costly than VCSELs (used in multimode SFPs).
SINGLE MODE SINGLE FIBER SFP TYPE WITHOUT SFP
The Single Mode Single Fiber SFP Type refers to a specific type of small form-factor pluggable (SFP) transceiver module.
It is designed for use with single mode fiber (SMF), which has a narrower core diameter (typically 9 µm) compared to multimode fiber.
These SFP modules are commonly used in long-distance communication applications due to their ability to transmit data over significant distances with minimal signal loss.
