Optimize High-Density Fiber Networks with Precision Attenuation
Telhua's Fiber Optical MPO Attenuator is engineered for data centers and enterprise networks where maximizing port density and ensuring signal integrity are critical. This solution directly addresses the challenge of managing optical power levels in compact MPO-based infrastructures, preventing receiver overload and minimizing bit-error rates without compromising rack space or installation efficiency.
Key Benefits for Network Architects
- Enhanced Density: Maintains high port count in MPO cassettes and enclosures by integrating attenuation directly into the connector path, eliminating the need for separate bulkhead attenuators.
- Superior Reliability: Features precision-machined ferrules and robust housing to ensure stable attenuation values and low insertion loss across thousands of mating cycles, critical for always-on environments.
- Rapid Deployment: Pre-terminated design allows for plug-and-play installation, significantly reducing field termination time and labor costs compared to inline alternatives.

Telhua Engineer's Tip
For optimal performance in QSFP28/100G links, select an attenuation value that brings received optical power to the mid-point of the transceiver's specified range. This margin accommodates temperature-induced laser drift and connector degradation over time, extending system longevity. Always verify polarity (Type A/B/C) alignment with your MPO trunk to avoid channel mismatch.
