Key Features

Engineered For Performance

Cost-Effective Splitting

FBT technology provides a lower-cost alternative to PLC splitters for applications requiring 1x2 or 2x2 split ratios, reducing per-port cost in simple distribution scenarios.

Environmentally Stable

Hermetically sealed steel tube package maintains consistent optical performance across -40°C to +85°C, suitable for both indoor and outdoor installations.

10-Year Warranty

Backed by a 10-year product warranty reflecting the proven long-term reliability of fused fiber technology in deployed telecom networks worldwide.

Flexible Coupling Ratios

Available with standard 50/50 or custom coupling ratios (e.g., 10/90, 20/80, 30/70) for monitoring taps, power balancing, and specialized distribution applications.

Typical Applications

01

FTTH/PON Access Networks

Cost-effective 1x2 splitting at fiber distribution points in FTTH last-mile deployments where only a small number of subscribers share a single feeder fiber.

02

Optical Power Monitoring

Asymmetric coupling ratios (e.g., 5/95 or 10/90) tap a small percentage of signal for real-time optical power monitoring without disrupting the main transmission path.

03

CATV Signal Distribution

Distributing broadband CATV optical signals in hybrid fiber-coax networks using 1310/1550nm wavelengths.
