Specifications

Description

The SC/UPC Fixed Attenuator 5dB is designed to reduce optical signal strength by a fixed 5 decibels. It is commonly used in FTTH, GPON, EPON, and other PON systems to prevent optical receivers from becoming saturated — especially when the fiber path is short or the optical transmitter is high power.

Specifications

Connector Type: SC/UPC (Square Connector with Ultra Physical Contact polish)
Attenuation Level: Fixed 5 dB (±0.5 dB tolerance)
Fiber Type: Single-mode (9/125 µm)
Wavelength Range: 1260 nm – 1625 nm (PON-compatible wavelengths: 1310, 1490, 1550 nm)
Return Loss: =50 dB (UPC polish)
Polarization Dependent Loss (PDL): <0.2 dB
Max Input Power: Typically up to +23 dBm (200 mW)
Operating Temperature: –40°C to +80°C

Features

PON-Ready Design: Supports standard GPON and EPON wavelengths — critical for ONUs and OLTs.
SC/UPC Connector: Standard blue connector used in most FTTH deployments (not angle-polished like APC).
Fixed 5 dB Attenuation: Reduces signal power without affecting signal quality.
Low Back Reflection: UPC polish gives a return loss of =50 dB — suitable for most PON networks.
Compact Plug-Style Format: Easily inserts between SC patch cords and equipment.
Telcordia GR-910 compliant: For long-term reliability in optical networks.

Ideal Use Cases in PON Systems

Application Area: How It Helps
FTTH deployments (GPON/EPON): Prevents signal overload at the ONU
Short fiber runs (<500 m): Reduces high Tx power from the OLT
Lab testing/calibration: Simulates real network attenuation levels
PON signal leveling: Balances split ratio power differences

Why Choose SC/UPC 5dB Attenuator for PON?

Perfect attenuation level (5 dB) for typical PON system balancing on short links.
Standard SC/UPC connector used in most ONU/OLT ports — no adapters needed.
Low return loss and minimal PDL ensures stable PON performance and accurate BER.
Cost-effective and plug-and-play, no configuration or recalibration required.
Compliant with telecom standards, supporting high reliability in real-world networks.
