Polarization Maintaining Fused WDM (488/532, 488/633, 532/633, 532/780, 633/780, 633/840 nm) | PM FBT Wavelength Division Multiplexer

Product Overview

Our Polarization Maintaining Fused Biconical Taper (PM FBT) WDMs are bidirectional fiber optic components engineered to multiplex and demultiplex two distinct visible laser wavelengths while fully preserving polarization state across both fiber axes. Manufactured via precision fused tapering technology, these devices deliver stable optical performance for visible fiber laser systems, biophotonics microscopy, fiber amplifiers and optical test instrumentation.

This series supports six standard wavelength combinations: 488/532, 488/633, 532/633, 532/780, 633/780, and 633/840 nm. Each model is pre-matched with dedicated PM panda fiber (PM460-HP or PM630-HP) to guarantee high polarization extinction ratio. Both polarization axes remain fully functional during operation; no axis will be blocked under normal working conditions.

Devices are offered bare fiber or terminated with Ø900 µm loose tube packaging, with optional FC/APC, FC/UPC, SC/APC or SC/UPC connectors. All units undergo 100% optical testing before shipment to ensure consistent loss, isolation and polarization performance.

Core Key Features

Ultra-low insertion loss (≤1.0~1.2 dB bare fiber) across full ±5 nm wavelength bandwidth
High port isolation up to 18 dB for long-wavelength visible combinations
High polarization extinction ratio ≥18 dB for reliable PM system alignment
Ultra-high return loss ≥55 dB to suppress back-reflection laser instability
Wide operating temperature range: -40 °C to +85 °C for industrial and laboratory environments
Multiple CW power handling ratings from 0.1 W to 0.3 W for different laser applications
Dual-axis active design, no polarization axis shielding
Two standard metal housing dimensions: Φ3.0×60 mm (bare fiber) / Φ3.0×70 mm (900 µm loose tube)
Customizable pigtail length, fiber type, wavelength pairs and connector terminations
Tensile load tolerance up to 5 N for standard fiber pigtails
RoHS compliant solid metal packaging with excellent mechanical stability

Typical Applications

Visible Wavelength Fiber Lasers & Pump Laser Combination Systems
Polarization-Maintaining Fiber Optical Amplifiers
Optical Test & Measurement Laboratory Instruments
Confocal Microscopy, Fluorescence Imaging & Biophotonics Equipment
Visible Light Fiber Sensing Systems
Multi-Wavelength Laser Delivery Paths

Frequently Asked Questions (FAQ)

Q1: Can this PM WDM be used for both multiplexing and demultiplexing?

A: Yes. The component is fully bidirectional. Combine two laser wavelengths at the common port, or split dual-wavelength input into two separate single-wavelength output arms.

Q2: How do connectors affect optical performance?

A: All connectorized versions will introduce minor performance degradation: +0.3 dB insertion loss, -5 dB return loss, and -2 dB extinction ratio compared to bare fiber units. Power handling capacity remains unchanged.

Q3: What is the difference between PM460-HP and PM630-HP fiber?

A: PM460-HP is optimized for shorter visible wavelengths (488 / 532 / 633 nm). PM630-HP is designed for longer visible bands (532/780, 633/780, 633/840 nm) to maintain superior polarization performance at longer wavelengths.

Q4: Can you provide custom wavelength combinations outside the listed standard series?

A: Custom wavelength pairs, high-power upgrades, extended fiber lengths and alternative connector types (LC, ST, MU) are available upon technical inquiry. OEM housing marking services are also supported.

Q5: What is the maximum tensile force allowed on the fiber pigtails?

A: The rated maximum tensile load is 5 N. Excessive pulling will damage the fused taper region and degrade optical performance permanently.

Q6: What temperature range is suitable for long-term operation?

A: -40 °C to +85 °C for continuous operation. Storage temperature matches the operating range; avoid condensation inside the metal package.
