Featuring LC/UPC male-to-female connectors, a ceramic core, and dustproof caps, it delivers low insertion loss and high return loss (≥50dB) across a wide operational wavelength (1200-1600nm) and temperature range (-40°C to +75°C). Perfect for optical communication networks, data centers, and CATV systems, it ensures stable, reliable performance in demanding environments. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JNNT52P | | Brand Name | H!Fiber.com | | Cable Type | Fiber Optic | | Color | 2 pcs | | Compatible Devices | Optical Fiber Distribution Frame, Optical Communication Network, Optical Fiber Broadband Access Network, Optical Fiber CATV, Optical Fiber Testers, FLAN | | Compatible Phone Models | No Compatible Phone Models | | Connector Gender | Male-to-Female | | Connector Type | Optical | | Country Of Origin | China | | Customer Reviews | 4.0 4.0 out of 5 stars (20) | | Indoor Outdoor Usage | Indoor | | Item Weight | 0.01 Kilograms | | Manufacturer | H!Fiber.com | | Model | AT-LC/LC-UPC-01-PT-SM-5dB-1-x2 | | Number of Pins | 2 | | Other Special Features of the Product | Lightweight | | Part Number | AT-LC/LC-UPC-01-PT-SM-5dB-1-x2 | | Recommended Uses For Product | Optical communication networks, data center networks, high power applications | | Unit Count | 2.0 Count | ## Product Details - **Brand:** H!Fiber.com - **Cable type:** Fiber Optic - **Connector type:** Optical - **Special features:** Lightweight ## Images ![H!Fiber.com LC/UPC Singlemode Fiber Optic Attenuator 5dB, 2 Pack, Male/Female, in-Line Attenuator, Single-mode Fixed - Image 1](https://m.media-amazon.com/images/I/61OI7xgKIPL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Frequently Bought Together - 2 Pack Single Mode LC 5dB Fiber Optic Attenuator, LC/UPC in-Line Fiber Attenuator, Male/Female, Single-mode Fixed, SM, dB Options: 3dB, 5dB, 7dB, 10dB - FLYPROFiber- 10dB LC Fiber Attenuator | dB Options: 3-20dB | LC/UPC SM Single Mode Fixed Fiber Optic Attenuator, Male to Female, 2pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/390113439-h-fiber-com-lc-upc-singlemode-fiber-optic-attenuator-5db](https://www.desertcart.pt/products/390113439-h-fiber-com-lc-upc-singlemode-fiber-optic-attenuator-5db) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-20*
