Technical FAQ: PL190A-1 Passive Optical Receiver
Q1: How can a passive optical receiver work without any electricity?
A： The PL190A-1 uses the energy contained in the 1550nm light. Our high-efficiency PIN photodiode converts the optical power directly into RF voltage, allowing it to drive the TV signal without any external power source.
Q2: What is the ideal optical input range for this passive node?
A： While it supports +6 to -9dBm, we recommend a -1 to -4dBm input. This ensures a clean 60dBµV+ output level, which is the field-proven standard for a direct connection to a Set-Top Box.
Q3: Can I customize the logo for my FTTH project?
A： 是的。我们提供 全面的OEM定制, including temporary logos, custom labels, and specialized packaging with an MOQ of just 1 piece for sampling.
Expert Selection Tip for Weak Signal Links
If your fiber link budget is tight (optical power below -9dBm), a passive receiver may not provide enough RF output. We recommend our
Active FTTH Optical Receiver with AGC
for stabilized 76dBµV+ output in low-power environments.
