Product information

Description

The BlueOptics SFA21XK7 LC 7dB Silver attenuator provides controlled optical attenuation for multimode fiber links, reducing signal strength by 7 dB on LC/UPC simplex connections. Designed for 50/125 µm multimode fibers at 850 nm, this compact silver attenuator uses a ceramic ferrule and industry-grade components to deliver stable loss characteristics and reliable mating performance. It is intended to prevent receiver overload on short-distance links or high-power transmitters, and is compatible with standard LC ports in networking equipment.

Advantages

The attenuator offers a precise 7 dB attenuation with low input loss and high return loss, supporting predictable signal reduction without introducing significant additional reflection. Built with high-quality fiber and branded connector components, it features a zirconia ceramic ferrule for durable mating cycles and consistent optical performance. The LSZH jacket and compliance with common industrial standards ensure safer installations in indoor and professional environments.

Suitable for

  • Multimode fiber networks (50/125 µm) operating at 850 nm
  • LC/UPC simplex ports on transceivers, switches and patch panels
  • Short-distance links where transmitter power must be reduced to avoid receiver saturation
  • Data centers, server rooms, telecom closets and laboratory test setups

Key specifications

  • Attenuation: 7 dB
  • Connector type: LC/UPC simplex
  • Fiber type compatibility: Multimode 50/125 µm
  • Operating wavelength: 850 nm
  • Ferrule material: Zirconia ceramic
  • Jacket: LSZH (low smoke zero halogen)
  • Operating temperature range: -40 °C to +75 °C
  • Durability: up to 1500 mating cycles (typical for installed connectors)

How to use

Insert the LC/UPC simplex connector of the attenuator into the device or transceiver receive port until it clicks securely, then connect the other end of the fiber link as required. Ensure connectors and ports are clean and free of dust before mating to avoid contamination-related losses. The attenuator is passive and requires no power or configuration; once installed it will reduce the optical power by approximately 7 dB at the specified wavelength.

Usage recommendations

Verify the required attenuation for your link using power meters or diagnostic tools before installation. Use the attenuator in combination with clean connectors and appropriate patch cords; avoid excessive bending near the connector and respect manufacturer temperature limits. For systems sensitive to return loss, choose the polish type and connector combination that matches your equipment requirements.
