1GE+3FE+CATV EPON ONU | Triplexer Optical Network Unit | IEEE 802.3ah Data + CATV Terminal

Product Overview

The Flypon1GE+3FE+CATV EPON ONU is a high-performance triplexer Optical Network Unit designed for operators delivering converged broadband data and cable television (CATV) services over a single fiber. Fully compliant with the IEEE 802.3ah EPON standard, this EPON ONU provides symmetric 1.25 Gbps data transmission alongside high-quality RF video overlay via the 1550nm CATV wavelength. Equipped with 1 Gigabit Ethernet port, 3 Fast Ethernet ports, and an RF coaxial output, it offers a complete triple-play access solution for FTTH, FTTB, and multi-tenant environments—eliminating the need for separate data modems and set-top box signal splitters .

Key Features:

· Triplexer WDM Technology – Data + CATV Over Single Fiber: Built with an integrated WDM (Wavelength Division Multiplexing) device, this EPON ONU simultaneously handles 1310nm upstream data, 1490nm downstream data, and 1550nm CATV broadcast signals over a single optical fiber. This triplexer design dramatically simplifies ODN cabling and reduces deployment costs for operators offering combined internet and cable TV packages .

· Full EPON Standard Compliance (IEEE 802.3ah): Engineered to meet the IEEE 802.3ah EPON specification, this 1GE+3FE+CATV EPON ONU ensures seamless interoperability with mainstream OLTs from ZTE, Huawei, FiberHome, and other EPON vendors. Supports advanced features including MPCP, FEC, DBA, and 128-bit AES encryption for secure data transmission .

· Flexible Multi-Port Wired Connectivity: Provides 1×10/100/1000Mbps auto-negotiation RJ45 GE port for gigabit-capable routers or high-performance devices, plus 3×10/100Mbps RJ45 FE ports for IPTV set-top boxes, desktop PCs, or network peripherals. This 4-port configuration eliminates the need for external switches in multi-device environments .

· Carrier-Grade CATV Receiver with AGC: The integrated CATV RF module operates at 1550nm with automatic gain control (AGC) functionality, maintaining stable RF output levels across a wide optical input range (typically +2dBm to -18dBm). Features include remote CATV port power-down capability via OLT management, high optical return loss (≥40dB), and MER ≥32dB for superior video quality. RF output covers 47-1000MHz, supporting analog and digital TV channels simultaneously .

· Comprehensive OAM Management & Security: Supports standard OAM (IEEE 802.3ah Clause 57) and extended OAM for remote configuration, performance monitoring, fault isolation, and firmware upgrades. Advanced features including port-based VLAN (802.1Q), QoS prioritization (802.1p), IGMP snooping, and broadcast storm suppression ensure optimal service delivery .

FAQ:

Q: How does the triplexer WDM technology work in this EPON ONU?

A: This EPON ONU integrates a triplexer WDM filter that separates three distinct wavelengths on a single optical fiber:

· 1310nm: Upstream data transmission from ONU to OLT

· 1490nm: Downstream data reception from OLT to ONU

· 1550nm: CATV broadcast reception (RF overlay)

This single-fiber, triple-wavelength design eliminates the need for separate fiber runs or external splitters, dramatically simplifying FTTH deployment for operators offering both internet and cable TV services .

Q: What is AGC and why is it important for CATV service quality?

A: AGC (Automatic Gain Control) automatically adjusts the RF amplifier gain to maintain a stable output level even as the incoming optical power varies. In this CATV EPON ONU, the AGC circuit ensures consistent RF output (typically 75-80dBuV) across an optical input range of +2dBm to -18dBm. This is critical for maintaining picture quality across subscribers at different distances from the OLT—whether they're at 1km or 20km from the central office .

Q: Can the CATV function be remotely controlled or disabled?

A: Yes. The EPON ONU supports remote CATV port control via OAM management. Operators can power down the CATV receiver module for subscribers who only subscribe to data services, reducing power consumption and extending device lifespan. The CATV function can be enabled or disabled without sending a technician to the premises .

Q: Is this 1GE+3FE+CATV EPON ONU compatible with my existing EPON OLT?

A: Yes. This EPON ONU is compliant with IEEE 802.3ah and tested for interoperability with OLTs from ZTE, Huawei, FiberHome, and other vendors using standard OAM protocols. For CATV overlay, it works with any standard 1550nm broadcast transmitter—no special OLT-side integration required beyond the optical overlay equipment .

Q: Can I use all four Ethernet ports simultaneously while watching CATV?

A: Absolutely. The data and CATV paths operate independently within the EPON ONU. The GE port and FE ports provide internet/IP connectivity, while the RF coaxial port delivers CATV signals directly to your television or set-top box. All services function concurrently without bandwidth competition—CATV uses dedicated 1550nm wavelength capacity completely separate from the data channels .

Q: What CATV RF performance can I expect from this ONU?

A: The integrated CATV receiver delivers carrier-grade RF performance:

· MER (Modulation Error Ratio): ≥32dB—excellent for digital QAM channels

· CNR (Carrier-to-Noise Ratio): >46dB—clean analog channel reception

· CSO/CTB: >58dBc—minimal composite distortions

· RF Bandwidth: 47-1000MHz—supports both analog and digital channel lineups
