The Thor Fiber Multi-Output F-EDFA-XX-YY series is designed for use in CATV, FTTH, and HFC networks. It’s well-suited for both long-distance optical transmission and local fiber distribution. Housed in a standard 19” rackmount chassis, each unit is available with 4,8, 16, 32, or 64 output ports, and supports a range of output power levels to meet various system requirements.
Output power is available from +14 dBm to +23 dBm, with custom configurations available upon request.
Operating in the 1550nm wavelength range, this amplifier series covers the full gain window of 1540–1560nm. It offers a reliable and cost-effective solution for scaling broadband video networks.
Thor’s multi-port EDFAs are engineered for high-performance transmission of both CATV RF analog signals (NTSC/PAL) and digital signals (QAM or ATSC). They utilize high-quality pump lasers and premium erbium-doped fiber components to ensure stable and long-lasting operation. Built-in APC, ACC, and ATC circuitry helps regulate output power and protect the system under varying conditions.
Each unit features a front-panel LCD display for real-time status and alarm monitoring. For added safety, the laser will automatically shut down if input power is lost, protecting both the equipment and your network.

Model Format: F-EDFA-XX-YY
XX = Number of Optical Outputs (2, 4,8,16,32 or 64 outputs via SC/APC or LC/APC connectors)
YY = Optical Output Power per Port in dBm (+14, 16,18,20, 22 and +23 dBm each)
These EDFAs are designed for distributing a single 1550nm input signal across multiple fiber outputs with precise power levels to compensate for optical losses in splitters and fiber runs.
Examples:
F-EDFA-8-16 – 8 outputs, each delivering +16 dBm optical power
F-EDFA-4-20 – 4 outputs, each delivering +20 dBm optical power
F-EDFA-8-18 – 8 outputs, each delivering +18 dBm optical power
F-EDFA-16-14 – 16 outputs, each with +14 dBm for mid-sized fiber distribution
F-EDFA-32-20 – 32 outputs, each with +20 dBm for large CATV or FTTH systems
F-EDFA-64-12 – 64 outputs, each with +12 dBm, ideal for short-distance or low-loss applications
To ensure proper power distribution across your network, follow this method:
Determine how many end-points (receivers) you need to serve.
Select the number of EDFA outputs based on the total number of splitters you'll deploy.
Account for optical losses:
Insertion loss of external splitters (e.g., ~14 dB for 1x16).
Fiber loss (~0.25 dB/km × distance).
Choose an EDFA model with sufficient output power per port to compensate for those losses.
Use: 32-output EDFA
Each output connects to a 1x16 external splitter → 32 × 16 = 512 receivers
Optical loss:
Splitter loss: ~14 dB
Fiber loss (20 km): ~5 dB
Total loss: ~19 dB
Receiver sensitivity: 0 dBm
Required EDFA output per port: ≥ +19 dBm
Recommended model: F-EDFA-32-20
(32 outputs, each with +20 dBm output power)
Model Format: F-EDFA-XX-YY
XX = Number of Outputs (2, 4, 8, 16, 32, 64)
YY = Output Power per Port in dBm (14, 16, 18, 20, 22, 23)
