Specifications

Description

The LC/UPC Fixed Attenuator 5dB is an inline fiber optic device designed to reduce optical signal power by a fixed amount of 5 decibels (dB) in single-mode fiber optic systems. It is commonly used to prevent receiver overload or to balance signal levels in fiber networks.

Specifications

Connector type: LC (Lucent Connector) with UPC (Ultra Physical Contact) polish
Attenuation: Fixed 5 dB (±0.5 dB typical tolerance)
Fiber type: Single-mode (9/125 µm)
Wavelength: Optimized for 1260 nm – 1620 nm (supports 1310 nm & 1550 nm telecom bands)
Return loss: Typically =50 dB (UPC polish has less return loss than APC but still good)
Insertion loss: 5 dB nominal attenuation plus minimal connector loss
Polarization Dependent Loss (PDL): <0.2 dB
Operating temperature: –40°C to +80°C
Max input power: Up to +23 dBm (200 mW) typical

Features

Fixed 5 dB attenuation: Provides consistent and reliable reduction in optical power
UPC polish connectors: Good return loss with flat physical contact, suited for many general telecom and data applications
Compact plug-and-play design: Easily inserted between LC patch cables and equipment
High mechanical durability: Zirconia ferrules with industry-compliant construction
Broad wavelength compatibility: Works well with standard telecom wavelengths

Ideal Use Cases

Signal level adjustment: When optical transmit power exceeds receiver input limits, especially in short fiber runs
General telecom & data networks: Suitable for systems where ultra-low back reflection is not critical but stable attenuation is needed
Testing and measurement: For equipment calibration and link budget verification
Fiber patch panels and distribution frames: Balancing optical power in fiber infrastructure

Why Choose LC/UPC Fixed Attenuator 5dB?

Effective Power Reduction: 5 dB is a common attenuation value to protect receivers and ensure optimal signal levels.
Reliable Performance: Factory-calibrated fixed attenuation ensures predictable, repeatable results.
Good Return Loss: UPC polish offers good performance for many standard optical systems.
Ease of Use: Plug-and-play design means no special setup or calibration needed in the field.
Cost-Effective: Usually less expensive than APC versions, making it ideal where ultra-low reflection isn’t mandatory.
