FAQ
FTTH Optical Receiver Frequently Asked Questions
Q1. What is an FTTH optical receiver?
A: An FTTH optical receiver is a device used in fiber-to-the-home (FTTH) networks. It is designed to receive optical signals from fiber optic networks and convert them into electrical signals for further processing.
Q2. How does FTTH optical receiver work?
A: The FTTH optical receiver adopts low-power optical reception and optical automatic gain control (AGC) technology. The AGC technology ensures that the received optical power remains within a specific range by adjusting the gain of the receiver. This ensures reliable signal reception and optimum performance.
Q3. What are the benefits of using FTTH optical receiver?
A: Using FTTH optical receivers brings several advantages to FTTH networks. It enables efficient fiber optic signal reception and conversion, enabling high-speed Internet, high-quality digital TV, and clear voice services. Additionally, it can be combined with an Optical Network Unit (ONU) or Ethernet over Coax (EOC) for triple-play services.
Q4. What are the applications of FTTH optical receivers?
A: FTTH optical receivers are mainly used in FTTH networks to connect residential or commercial premises with fiber optic infrastructure. It acts as an endpoint device that takes optical signals traveling through fiber optic cables and converts them to electrical signals suitable for various services, including Internet, television, and voice.
Q5. Can the FTTH optical receiver be used with other equipment?
A: Yes, FTTH optical receiver can be used together with ONU or EOC to realize triple play service. The ONU acts as a central hub for distributing Internet, TV and voice signals within the premises, while the FTTH optical receivers ensure reliable reception and switching of these signals. Together, they support seamless connectivity and multimedia services in FTTH networks.
