PSM-002 Polarization Scrambler

1060, 1310, 1550 nm; IL <1.2, <0.1 dB; SOP Recovery Time 0.9 ms; Tracking Speed 47 π/s; SOP Accuracy <0.1 dB; RL >50 dBLunas’ POS-002 polarization tracker automatically adjusts the state of polarization (SOP) towards a reference SOP, counteracting continuous input SOP variations as fast as 0.9 ms with no resets.The reference SOP is determined by a feedback signal which can be provided either internally or externally. The internal feedback version (POS-002-I) consists of a fiber squeezer polarization controller, in-line polarization monitor, digital and analog circuits, and proprietary algorithm. The error signal from the polarization monitor is fed back to the polarization controller to maintain a linear SOP at the output. The output fiber for POS-002-I is typically polarization maintaining (PM) fiber with the SOP aligned to its slow axis.The external feedback version (POS-002-E) replaces the internal polarization monitor with an external analog electrical feedback signal of the user’s choice, such as a voltage proportional to the degree of polarization (DOP) measured by a polarimeter, the bit-error rate (BER) from a BER chip, the RF spectrum of a detected signal, or the optical power after a polarizer. The output fiber is typically single mode (SM) fiber.Key Features:Reset-free OperationState of Polarization (SOP) Recovery Time: <3 ms, 0.9 ms TypicalSOP Rotation Tracking Speed: 47 π/s"Plug and Play" IntegrationOperating Wavelength Range: 1060 ±50 nm, 1310 ±50 nm, or 1550 ±50 nmSOP Accuracy: <0.1 dBRepeatability: <0.1 dBInsertion Loss (IL, Internal Feedback): <1.2 dB, 0.8 dB TypicalInsertion Loss (IL, External Feedback): <0.1 dBReturn Loss (RL): >50 dBIsolation in Orthogonal Polarization: 20 dBOptical Power Handling: <20 dBmCommunications Interface: RS-232Dimensions: 19.1 x 98 x 184 mmApplications: PMD Compensation; Polarization Division Demultiplexing; Elimination of Polarization Fading in Coherent Detection and Fiber Sensor Systems; Suppression of Noise Figure in Optical Amplifiers; Reduction of PDL Effects
