CATV Optical Transmission Equipment — China Supplier & Manufacturer
CATV optical equipment carries analog and digital television signals over fiber using 1310 nm and 1550 nm wavelengths. Fiber Optic Telecom (FOT) supplies direct and externally modulated optical transmitters, FTTH WDM optical receivers and Erbium-Doped Fiber Amplifiers (EDFA) for head-ends, distribution networks and FTTH triple-play deployments.

How to Choose
- Pick the wavelength for your reach — 1310 nm suits short to medium links; 1550 nm with EDFA amplification is the choice for long-distance and split distribution.
- Choose direct vs. external modulation — direct modulation (DFB) is cost-effective for shorter spans; external modulation (LiNbO3) gives superior CNR/CTB/CSO for long-haul 1550 nm transmission.
- Size the optical output power — add the splitter losses and fiber attenuation (~0.25 dB/km at 1550 nm) to the receiver sensitivity to find the transmitter power needed; add EDFA when one transmitter must feed many nodes.
- Match the receiver to the service — FTTH WDM receivers separate 1550 nm CATV from 1310/1490 nm PON for triple-play ONTs; verify the RF output level meets your set-top box input.
- Confirm management and redundancy — rack transmitters offer SNMP/LCD monitoring and dual power; specify AC or DC power and any SNMP requirement.
Frequently Asked Questions
Equipment Buyer Questions
What is the difference between 1310 nm and 1550 nm CATV transmitters?
1310 nm transmitters are used for short/medium links (typically <20 km) without amplification. 1550 nm transmitters pair with EDFA amplifiers for long-distance transmission and optical splitting to many receivers.
What does an EDFA do in a CATV network?
An Erbium-Doped Fiber Amplifier boosts a 1550 nm optical signal without optical-electrical conversion, allowing one transmitter to feed many distribution nodes over long distances.
What is a FTTH WDM CATV receiver?
It separates the 1550 nm CATV signal from the 1310/1490 nm PON wavelengths on a single fiber, delivering an RF output for the subscriber's CATV/ONT in a triple-play network.
What CNR/CTB/CSO performance do FOT transmitters provide?
Listed transmitters specify CNR ≥51 dB, CTB ≤-65 dBc and CSO ≤-60 dBc; confirm the exact figures for your model and channel loading with FOT.
Can FOT supply outdoor or mini CATV transmitters?
Yes — the FCOT-2150M mini transmitter suits small-scale and space-constrained FTTH deployments. Share the installation environment so FOT can confirm the suitable model.
