Technical Datasheet Note
With connectors, IL increases by 0.3 dB, RL decreases by 5 dB and ER decreases by 2 dB. Custom configurations, fiber types for Port 3, and connector terminations are confirmed during quotation.
Configuration and ordering notes

PBS and PBC operation use different port functions. Port 3 fiber type and polarization behavior are reviewed against the intended optical layout.

Selection Guidance: Review footprint reduction, splice elimination and optical loss budget in our Mini & Hybrid Devices for CPO & Transceivers Guide ↗ or Mini vs Standard Isolator Guide ↗.

Key Applications

EDFA & Raman amplifier pump combining; Coherent optical communication systems; Fiber sensor polarization multiplexing; Photonics R&D modules.
