Specifications

Description:

The High Power CWDM Attenuator SC/APC 20dB is a passive optical component specifically designed to reduce the power of optical signals by a fixed 20 decibels (dB) in coarse wavelength division multiplexing (CWDM) systems. Featuring an SC/APC connector (Angled Physical Contact for low back reflection) and optimized for high-power applications, this attenuator is ideal for managing excess signal levels in CWDM transmission without degrading signal integrity. It is engineered to handle higher optical power than standard attenuators, making it suitable for use in systems with EDFA amplification, CATV, and long-reach optical transport.

Features:

Fixed Attenuation: 20 dB (±1 dB tolerance)
Connector Type: SC/APC (angled polish for minimal return loss)
Wavelength Support: CWDM channels (typically 1270–1610 nm)
High Power Tolerance: Supports optical power levels up to 1W (30 dBm) or more
Return Loss: = 60 dB (APC polish)
Low Insertion Loss Beyond Attenuation: Typically = 0.6 dB
Fiber Type: Single-mode fiber (G.652 or equivalent)
Compliance: RoHS and Telcordia GR-910 certified

Specifications:

Attenuation Level: 20 dB ± 1 dB
Connector Type: SC/APC
Polish Type: Angled Physical Contact (APC)
Wavelength Range: 1270 nm – 1610 nm (CWDM band)
Max Input Optical Power: Up to 1 Watt (30 dBm) or higher
Return Loss: = 60 dB
Insertion Loss: = 0.6 dB (excluding attenuation)
Operating Temperature: -40°C to +85°C
Storage Temperature: -40°C to +85°C
Fiber Compatibility: Single-mode fiber (G.652.D)

Ideal Applications:

CWDM Networks: Balance optical power across different CWDM wavelengths
CATV Headends & Distribution: Prevent overload in optical receivers
EDFA-Based Amplified Links: Manage signal strength in long-haul systems
Test and Measurement Labs: Simulate high-loss conditions for CWDM systems
High-Power FTTH & PONs: Safely attenuate optical signals for end-user equipment

Why Choose This Product?

Engineered for CWDM: Optimized across the full CWDM spectrum for consistent performance
Handles High Optical Power: Suitable for EDFAs and high-output transceivers
SC/APC Interface: Angled polish eliminates back reflections that can interfere with DWDM/CWDM channels
Durable & Reliable: Designed for demanding environments with high thermal and optical stability
Plug-and-Play: Easy to install without requiring active control or monitoring
