Top manufacturers of LC fiber optic attenuators include FS, ACON OPTICS, SENKO, Fibertronics, and L-com, offering a range of fixed and variable attenuators for single-mode and multi-mode applications.

Leading Manufacturers and Their Offerings

FS provides both fixed and variable fiber optic attenuators with attenuation ranges from 0 to 60dB, suitable for WDM transmission and ensuring stable performance across various fiber networks . ACON OPTICS specializes in high-quality LC attenuators with male-female plug configurations, offering ultra-low return loss and attenuation levels from 1dB to 40dB. They support multiple connector types (LC, SC, FC, ST, MU) and finishes (PC or APC), and have over 20 years of experience in fiber optic interconnect solutions for telecommunications, data centers, and FTTH applications . SENKO manufactures premium LC and SC APC attenuators certified to GR-910 standards. Their products feature one-piece body construction for superior side load support, doped fiber technology for wide wavelength operation (1270–1650nm), and can operate in extreme temperatures (-40°C to 75°C) with attenuation levels from 1–30dB . Fibertronics, Inc. offers a broad selection of LC attenuators for single-mode (9/125) and multi-mode (50/125, 62.5/125) fibers. They provide male-to-female, in-line, and adjustable attenuators with customizable lengths and connector types, including LC, LC/APC, SC, SC/APC, FC, FC/APC, and ST . L-com supplies dual-wavelength (1310/1550nm) single-mode LC attenuators suitable for lab and commercial applications. Their in-line attenuators are factory tested, available in multiple connector styles and polish types, and designed for high reliability in both testing and operational environments .

Key Considerations When Choosing a Manufacturer

• Attenuation Range: Ensure the manufacturer provides the required dB levels for your application.
• Connector Type and Polish: LC, LC/APC, SC, SC/APC, and other types; APC polish reduces back reflection.
• Single-mode vs Multi-mode: Match the attenuator to your fiber type (9/125 for single-mode, 50/125 or 62.5/125 for multi-mode).
• Certifications and Reliability: Look for GR-910 or other industry certifications for network-critical applications.
• Environmental Tolerance: Consider operating temperature range and power handling if used in harsh conditions. These manufacturers are recognized for their quality, experience, and broad product lines, making them reliable partners for sourcing LC fiber optic attenuators.
