Specifications

Description

A high-precision variable optical attenuator designed to finely control the optical signal power through manual adjustment. Featuring LC/UPC connectors, this VOA supports single-mode applications across key telecom wavelengths, making it well-suited for lab testing, telecom links, and fiber network calibration

Features

Wide Attenuation Range: Typically adjustable from 0.6 dB up to 30–60 dB, depending on model
High Precision: Attenuation steps with precision as fine as ±0.02 dB
Low Insertion Loss: Additional loss 0.6dB aside from the set attenuation
Low Polarization-Dependent Loss (PDL): Typically <0.10 dB
High Return Loss: UPC: >55dB; APC variants may exceed65dB
Stable & Reliable: Excellent stability across environmental changes, with consistent performance over time

Specifications

Parameter: Typical Value
Wavelength: 1260–1610nm (customizable; often 1310 or 1550nm)
Attenuation Range: 0.6 to 30 or 60dB
Precision: ±0.02dB
Insertion Loss: <0.6dB
PDL: <0.10dB
Return Loss: UPC >55dB, APC >65dB
Connector: LC/UPC inline duplex or simplex
Operating Temp: –20°C to +80°C
Cable Length: Typically 1–2 m, 2mm cable diameter
Typical Dimensions: ~26×8×18 mm (body block)
Fiber Type: Singlemode (9/125µm SMF)

Ideal Uses

Optical system tuning & calibration: Precise attenuation control for aligning channel power in WDM networks
Testing environments: Manually simulate fiber link loss or perform margin testing
Avoiding receiver saturation: For sensitive optical receivers when fiber run is short or launch power is high
FTTH, CATV, LAN: When precise power balancing is needed in access or distribution systems
Fiber sensor systems: To calibrate signal power for sensors or measurement links
Lab and R&D: Offers manual control in development and performance testing setups

Why Choose This High-Precision LC/UPC VOA?

Precision Attenuation Control: ±0.02dB resolution gives finer adjustments than fixed attenuators.
Wide Dynamic Range: Models up to 60dB allow flexible use in various signal power scenarios.
Low Loss & PDL: Maintains signal integrity—ideal for high-bandwidth or sensitive systems.
Good Return Loss: Ensures minimal back-reflection, especially in UPC-terminated units.
Versatile & Plug-and-Play: No external power; fits standard LC/UPC fiber links and test setups.
