Specifications

Description

The Rack-Mount Variable Attenuator Module – WDM Ready is a high-performance optical device designed to provide precise and adjustable attenuation of fiber optic signals in a standard 19-inch rack-mountable form factor. It is engineered for seamless integration into WDM (Wavelength Division Multiplexing) systems, where maintaining balanced signal levels across channels is critical.
This module allows manual or remote adjustment of attenuation levels, making it ideal for network operation centers (NOCs), lab environments, or long-haul telecom infrastructure that requires centralized control and monitoring of optical signal strength.

Features

Rack-Mount Design: Standard 1U or 2U height for seamless integration in telecom/data center racks.
Adjustable Attenuation: Precision control typically from 0–30 dB.
WDM Ready: Wide wavelength support (1260–1650 nm), compatible with DWDM/CWDM systems.
Multi-Port Configuration: Often available with 4, 8, or 16 ports for high-density applications.
Manual or Remote Control: Via front-panel knobs or software/RS-232/RS-485/Ethernet interface.
High Return Loss & Low Insertion Loss: Minimizes signal degradation and reflections.
Stable and Repeatable: Excellent repeatability for lab or field calibration.
Built-in Display (Optional): Real-time attenuation readout via LCD or digital interface.

Specifications

Attenuation Range: 0 – 30 dB (variable, step or continuous)
Wavelength Range: 1260 – 1650 nm (DWDM/CWDM compatible)
Insertion Loss: = 1.0 dB (at 0 dB attenuation)
Return Loss: = 50 dB (UPC), = 60 dB (APC)
Control Method: Manual, RS-232, RS-485, Ethernet (varies by model)
Operating Temperature: -10°C to +60°C
Connector Types: LC, SC, FC (UPC/APC, customizable)
Rack Unit Size: 1U or 2U, 19-inch standard rack
Number of Channels: 1 to 16 (depending on configuration)

Ideal Uses

WDM System Power Equalization: Match channel powers to prevent gain tilt and cross-talk.
Optical Amplifier Testing: Protect EDFAs from overloading and simulate link losses.
Long-Haul & Metro Networks: Control link budgets without disrupting fiber paths.
Data Centers & Central Offices: Balance multi-channel optical connections.
Network Labs & R&D: Perform precision testing under various attenuation conditions.
Monitoring & Simulation: Create loss profiles in live or simulated network conditions.
Field Deployments: Reliable inline power control in outdoor cabinets or POPs.

Why Choose Rack-Mount Variable Attenuator Module – WDM Ready?

WDM Compatibility: Optimized for DWDM/CWDM systems, ensuring clean channel isolation.
Scalable & Centralized: Supports multi-port configuration in a compact rack module.
Flexible Control Options: Manual or remote adjustment based on network requirements.
Minimized Downtime: Inline attenuation without physical reconnections.
Professional Design: Rugged housing, ideal for mission-critical network environments.
Easy Maintenance: Front-access ports and monitoring interface for real-time adjustments.
