Specifications

Description

A CWDM Fixed Optical Attenuator (10?dB) is a passive fiber optic device that reduces optical signal power by exactly 10 decibels. It is specifically designed for Coarse Wavelength Division Multiplexing (CWDM) systems, which use multiple wavelengths (typically from 1270?nm to 1610?nm) over a single fiber. This attenuator is built to work seamlessly across the CWDM wavelength spectrum while preserving signal integrity and ensuring safe levels at the receiver end.

Specifications

Product Type: Fixed Optical Attenuator (for CWDM applications)
Attenuation: 10?dB ±0.5?dB
Wavelength Range: 1270?nm – 1610?nm (CWDM spectrum)
Connector Type: SC/UPC, SC/APC, LC/UPC, LC/APC, or others (based on system design)
Fiber Type: Singlemode Fiber (SMF-28 or equivalent)
Return Loss: =55?dB for APC / =50?dB for UPC
Insertion Loss: =0.6?dB (excluding 10?dB attenuation)
Operating Temperature: –40?°C to +75?°C
Storage Temperature: –40?°C to +85?°C
Polarization Dependent Loss (PDL): =0.1?dB
Power Handling: Up to 500?mW (higher power options available)
Compliance: RoHS, Telcordia GR-910, ITU-T G.694.2 (CWDM)

Features

Designed for CWDM: Wide operating wavelength range matches CWDM grid (1270–1610?nm).
Fixed 10?dB attenuation: Ensures consistent signal reduction across all channels.
Low PDL & insertion loss: Minimal signal distortion, critical for multiplexed signals.
Available in multiple connector types: Easily integrates into existing CWDM equipment.
High power compatibility: Supports high-output transceivers used in CWDM SFPs/XFPs.

Ideal Use Cases

Balancing channel power in CWDM systems to ensure uniform signal strength.
Preventing receiver saturation on short fiber runs with high-output CWDM optics.
Lab testing and simulation of network load in CWDM environments.
Metro or access network installations using CWDM transceivers over variable distances.

Why Choose This Product for CWDM?

Spectral Compatibility: Unlike general-purpose attenuators, CWDM-specific versions are optimized across the full CWDM grid.
Receiver Safety: Protects the optical receiver from overpowering, especially in short-haul CWDM applications.
Channel Equalization: Helps balance mismatched CWDM channel powers due to different transmission losses or launch powers.
Reliable and Passive: No power or calibration needed — just plug and go.
