Project Quotation for Erbium-Doped Fiber Amplifier OSFP

A project quotation for an EDFA (OSFP) should include the amplifier type, gain, output power, pump configuration, fiber length, polarization requirements, and optional accessories such as isolators and gain-flattening filters.

Technical Specifications

1. Amplifier Type: Core-pumped EDFA suitable for OSFP modules, supporting single-mode (SM) or polarization-maintaining (PM) fibers . 2. Wavelength Range: C-band (1530–1565 nm) with optional L-band extension up to 1625 nm . 3. Pump Laser: 980 nm or 1480 nm diode lasers, with co-propagating or counter-propagating configurations . 4. Fiber Length: Typically 10–30 meters of erbium-doped fiber; for simulation or lab setups, 14 m is common for achieving 20–40 dB gain . 5. Gain and Output Power:

• Small-signal gain: 20–40 dB
• Saturated output power: +17 to +24.5 dBm depending on model (e.g., Thorlabs EDFA100 >20 dBm, EDFA300 >24.5 dBm), . 6. Noise Figure: Typically <5 dB for high-quality EDFAs . 7. Polarization:
• SM models: polarization-insensitive
• PM models: amplify only along the slow axis . 8. Accessories:
• Input/output optical isolators to prevent back-reflection
• Optional gain-flattening filters for uniform spectral response
• Wavelength-division multiplexers for pump-signal combination .

Integration Considerations

• Ensure compatibility with OSFP module connectors (e.g., FC/APC 2.0 mm narrow key)
• Account for insertion losses in connectors and demultiplexers (typically 0.5–1.5 dB per component),
• Consider pump power availability and thermal management for long-term stability .

Cost Estimation Framework

While exact pricing depends on supplier, model, and configuration, a typical commercial EDFA module (e.g., Thorlabs EDFA100/300 series) ranges from $5,000 to $15,000 USD per unit, depending on output power, polarization type, and optional accessories . Additional costs may include gain-flattening filters, isolators, and integration hardware.
