## Overview

This 2-pack of single-mode LC/UPC fiber optic attenuators delivers fixed 5dB attenuation with ultra-low insertion loss and high return loss (≥50dB). Crafted with a ceramic core for stability and durability, these lightweight inline attenuators prevent optical receiver overload, ensuring low bit error rates and reliable long-haul network performance across CWDM/DWDM, CATV, and data center applications.

## Description

Parameters • Operation Wavelength:1200nm - 1600nm • Return Loss: ≥ 50dB • Attenuation Tolerance: ±10% dB • Operational Temperature: -40 to+ 75°C • Core material: Ceramic • Using dustproof cap to protect the end-face. • Using an attenuator to prevent over saturating an optical receiver when the optical power is too high and ensures low bit error rates preventing damage to receiving fiber optic equipment. Attenuator Application • Optical attenuator is a passive device used to reduce the power level of an optical signal. It is generally used in single-mode long-haul applications to prevent optical overload at the receiver. Optical attenuator is widely used in CWDM&DWDM, CATV systems, data center networks, test equipment and other high power applications.

## Features

- LC/UPC Fiber Optic Attenuator: LC/UPC Male to LC/UPC Female, 5dB, single mode fixed, Ceramic Core material, 2 Pack.
- Low Insert-loss & High Return-loss: Polarization dependent loss ≤0.2dB and Return Loss: ≥ 50dB. Using an attenuator to prevent over saturating an optical receiver when the optical power is too high and ensures low bit error rates preventing damage to receiving fiber optic equipment.
- Good Repeatability & Intercalation: Widely used in Optical Fiber Distribution Frame, Optical Communication Network, Optical Fiber Broadband Access Network, Optical Fiber CATV, Optical Fiber Testers, FLAN, the performance is stable and reliable.
- Feature: Light weight, small volume, high accuracy, good stability and convenient operation.
- Attenuator Application: Optical attenuator is a passive device used to reduce the power level of an optical signal. It is generally used in single-mode long-haul applications to prevent optical overload at the receiver.
