LUNA POS-202 – Polarisation Stabiliser, 2 Port
- Simple, reset free operation
- PM output
- Low insertion loss
The LUNA POS-202, POS-203 and POS-204 polarisation stabilisers maintain stable output states of polarisation (SOP) against rapid input SOP fluctuations, compensating for an input polarisation discontinuity in as fast as 5 ms, or tracking without resets against a continuous input SOP rotation of up to 32π/s. The POS-20X architecture includes a polarisation controller, in-line polarisation monitor, and proprietary algorithms.
The LUNA POS-202 has optical ports for signal input and output. It stabilises the output SOP to linear, aligned to the slow axis of the output PM fiber.
APPLICATIONS
- Eliminate polarisation fluctuations in fibre systems
- Suppress noise figure in optical amplifiers
- Reduce PDL effects
- Demultiplex polarisation division multiplexed channels
