FSK-OP101  /  V-ONU OPTICAL RECEIVER

Product Overview

The FSK-OP101 is an in-building V-ONU optical receiver designed for CATV/UHF and BS/CS satellite broadcasting systems. It converts optical signals transmitted over single-mode fiber into RF signals for television distribution in FTTH and in-building networks.

Supporting CATV/UHF frequencies from 70 to 770 MHz and BS/CS frequencies from 1032 to 2681 MHz, the receiver is compatible with 4K satellite broadcasting applications.

The FSK-OP101 integrates optical automatic gain control (AGC), high RF output and FSK remote control, allowing operators to manage CATV and satellite RF outputs individually from central equipment.

Frequently Asked Questions

What frequency bands does the FSK-OP101 support?

The specified operating frequencies are 70–770 MHz for CATV/UHF and 1032–2681 MHz for BS/CS. The receiver supports applicable 4K satellite broadcasting services within these specified bands.

How does FSK remote control work?

The FSK-OP101 receives control signals using a 75.5 MHz FSK carrier. Each receiver can be individually addressed, allowing central equipment to enable or disable the CATV/UHF and BS/CS RF outputs.

What is the optical AGC operating range?

The optical AGC operates from −14 to −4 dBm, maintaining RF output stability within the specified AGC variation limits.

Which optical and RF connectors does the FSK-OP101 use?

The receiver uses an SC/SPC optical connector for single-mode fiber input and a 75 Ω F-type RF output connector.

Can the FSK-OP101 be powered through the RF output connector?

Yes. With the AC power supply unit removed, the receiver can be powered through its RF output terminal using 13.5–15.8 V DC.
