PL190A-3D: Zero-Power WDM Passive Node with Dual RF Outputs
The high-efficiency, maintenance-free passive optical receiver designed for dual-TV distribution in GPON FTTH networks.
- Maintenance-Free Passive Design: 这个 wdm passive node operates entirely without an external power supply, converting optical power directly into RF signals—ideal for locations without nearby power outlets.
- Dual RF Output Ports: Unique “D-style” configuration with two RF outputs, allowing a single node to provide high-quality CATV signals to two TV sets or Set-Top Boxes (STBs) simultaneously.
- GPON Integration: Features a high-isolation built-in FWDM filter that passes 1310/1490nm data signals to the ONU while extracting 1550nm for broadcasting services.
- Exceptional Signal Quality: Despite being passive, it delivers a robust output level of ≥56dBµV per port (at 0dBm input), supporting clear Digital TV and HDTV reception.
- Environmental Adaptation: Encased in a durable PVC housing with an operating temperature range of -40 至 +85℃, ensuring long-term reliability in diverse indoor environments.
Technical FAQ: PL190A-3D WDM Passive Node
Q1: Does the wdm passive node really require no electricity?
A： Exactly. The PL190A-3D wdm passive node utilizes a high-sensitivity PIN diode that harvests energy directly from the 1550nm optical carrier. This “Green” technology makes it an excellent choice for reducing the carbon footprint of your FTTH network while simplifying the installation for end-users.
Q2: Can I connect this node directly to my television?
A： 是的。 wdm passive node is designed to connect directly to the RF tuner of a TV or a Digital Set-Top Box (STB) via standard F-type coaxial cables. Its low-loss circuit ensures that even without an active amplifier, the digital signal remains well within the required threshold for 4K/HD viewing.
Q3: How does the PON pass-through port affect my internet speed?
A： It has virtually no impact. The internal FWDM filter is optimized for ultra-low insertion loss (≤1.0dB) at the 1310/1490nm wavelengths. Your GPON ONU will receive the data signal with full strength, ensuring that high-speed VoIP and broadband services are maintained at peak performance.
