Carrier-Grade Optical Transmission & Fiber Distribution Infrastructure

SOUKA multi-port EDFAs utilize carrier-grade 980nm and 1480nm pump lasers combined with high-purity erbium-doped optical fiber coils, maintaining an ultra-low noise figure (NF < 5.0 dB).
Built-in microcomputer-managed Automatic Power Control (APC) and Automatic Temperature Control (ATC) circuits lock pump output power and laser diode operating temperatures in real time. This active stabilization eliminates gain tilt and keeps Composite Second Order (CSO) and Composite Triple Beat (CTB) distortion levels well below -65 dBc across all output splits.

SOUKA optical receivers feature an integrated wide-dynamic optical AGC circuit covering -18 dBm to +2 dBm. An internal photodiode detector continuously measures received optical power and regulates dynamic PIN attenuation stages before the RF amplification block.
Even when physical fiber link lengths vary or patch splices degrade, the receiver holds RF output levels rock-solid at 80–90 dBµV per channel with Carrier-to-Noise Ratio (CNR) >51 dB, preventing signal clipping, intermodulation hum, or snowy screens on downstream TVs.

1310nm transmitters operate near the zero-dispersion window of standard G.652 single-mode fiber, making them ideal and cost-effective for localized distribution and short-to-medium runs (<15–20 km) without requiring optical amplifiers.
1550nm transmitters exhibit significantly lower optical attenuation (~0.20 dB/km compared to ~0.35 dB/km at 1310nm) and are fully compatible with Erbium-Doped Fiber Amplifiers (EDFA) and Dense WDM. Choose 1550nm for long-haul trunk transmission (30+ to 100+ km) and high-split multi-node FTTx architectures.

Outdoor optical nodes and FTTH receivers are housed in heavy-duty zinc-aluminum die-cast enclosures delivering >100 dB RFI shielding isolation and IP65/IP67 weatherproofing against moisture, lightning transients, and electromagnetic ingress.
For headend rack units, dual hot-swappable AC 110V/220V and DC -48V power supplies provide uninterrupted failover. Integrated RJ45 SNMP and Web-GUI interfaces export live telemetry—including laser bias current, TEC cooling voltage, input optical power, and internal chamber temperature—for 24/7 automated network monitoring.
