NewOpto SM Series Single-Mode Fiber Patch Cables

Overview

NewOpto SM Series single-mode fiber patch cables are precision-engineered optical interconnect solutions designed for demanding laboratory, research, and industrial photonics applications. These cables utilize high-purity fused silica core fibers optimized for low attenuation and minimal modal dispersion across an exceptionally broad spectral range—from deep ultraviolet (305 nm) to mid-infrared (2100 nm). Each cable is constructed with industry-standard single-mode fiber (e.g., SMF-28 compatible variants, UV-grade silica, or specialty IR fibers), selected and characterized per wavelength band to ensure optimal mode field matching, polarization-maintaining compatibility where required, and long-term mechanical stability under repeated mating cycles. The fundamental operating principle relies on guided-wave propagation in the fundamental LP₀₁ mode, with precise control over numerical aperture, cutoff wavelength, and bend-insensitive performance—critical for coupling efficiency in free-space-to-fiber and fiber-to-fiber interfaces.

Key Features

• Ultra-broad spectral coverage: 305–2100 nm, segmented into 14 discrete wavelength-optimized configurations
• Wavelength-specific mode field diameters (MFD): Ranging from 3.0 µm @ 450 nm to 13.0 µm @ 2100 nm—ensuring minimal insertion loss and backreflection when interfaced with lasers, detectors, or modulators
• Low-insertion-loss connectors: Precision ceramic ferrules with ≤0.2 dB typical insertion loss (per connection) and repeatability < ±0.05 dB
• Ultra-low backreflection options: FC/APC terminations deliver < −60 dB return loss; FC/PC variants maintain < −40 dB
• AR-coated variants available: Broadband anti-reflection coatings applied directly to fiber end-faces for enhanced transmission (>99.5% per interface) in UV–VIS–NIR bands
• Hybrid connector configurations: FC/PC–FC/APC and FC/PC–SMA assemblies support heterogeneous optical systems without intermediate adapters
• Ruggedized construction: 900 µm tight-buffered fiber, reinforced strain relief boots, and 2.0 mm or 3.0 mm jacket options (PVC or LSZH)

Sample Compatibility & Compliance

These patch cables are routinely deployed in alignment-critical optical setups including ultrafast laser systems (Ti:Sapphire, Yb-fiber, OPOs), quantum optics experiments (SPDC, homodyne detection), spectroscopic instrumentation (FTIR, Raman, fluorescence lifetime), and telecom/datacom test benches. All cables comply with IEC 61753-1 (performance categories for fiber optic interconnecting devices) and IEC 61300-2-2 (vibration testing) standards. FC/PC and FC/APC terminations conform to IEC 61754-13 and IEC 61754-20 specifications. For regulated environments—including GLP-compliant analytical labs and ISO/IEC 17025-accredited calibration facilities—traceable certification documentation (including IL/RL test reports per IEC 61300-3-4) is available upon request. No FDA or CE marking applies, as these are passive components exempt from directive-level conformity assessment.

Software & Data Management

As passive optical components, NewOpto SM Series patch cables require no embedded firmware, drivers, or software integration. However, full metrological traceability is supported through optional calibration certificates (NIST-traceable reference measurements of insertion loss and return loss at specified wavelengths). Test data—including spectral IL curves (350–2000 nm), MFD verification reports, and environmental aging logs (thermal cycling, humidity exposure)—are archived and accessible via secure customer portal upon order fulfillment. For LIMS or ELN integration, structured XML/CSV reports can be generated to align with 21 CFR Part 11 audit trail requirements when used within validated optical measurement workflows.

Applications

• Free-space laser beam delivery and collimation (e.g., coupling into high-NA objectives or fiber-coupled detectors)
• Interfacing tunable lasers, supercontinuum sources, and OPOs with spectrometers or interferometers
• Building stable Michelson, Mach–Zehnder, or Sagnac interferometers requiring phase-stable, low-backreflection paths
• UV photolithography alignment systems and deep-UV fluorescence microscopy light paths
• Fiber-based sensing platforms (e.g., FBG interrogation, distributed temperature/strain sensing)
• Quantum key distribution (QKD) receiver modules where polarization extinction ratio and timing jitter are sensitive to connector reflectivity
• Calibration of optical power meters, spectroradiometers, and integrating sphere systems

FAQ

What is the maximum power handling capability of these patch cables?
Standard versions are rated for continuous-wave (CW) power up to 500 mW at 1550 nm and 300 mW at 1064 nm. For higher-power applications (e.g., pulsed lasers), custom versions with angle-polished ends and fused-silica core/clad geometry are available.
Can I request custom lengths outside the standard 1/2/5/10 m options?
Yes—custom lengths from 0.3 m to 50 m are manufacturable with lead times of 10–15 business days. Tolerance is ±5 mm for lengths ≤5 m and ±0.1% for longer assemblies.
Do you offer polarization-maintaining (PM) variants of these single-mode patch cables?
Yes—NewOpto supplies PM versions (e.g., Panda or Bow-tie fiber) with extinction ratios >25 dB across all listed wavelength bands; model numbers begin with “PM” prefix.
Are these cables suitable for vacuum or cryogenic environments?
Standard versions operate from −40 °C to +85 °C. For UHV (<10⁻⁹ mbar) or cryogenic use (4 K), we supply stainless-steel armored or metal-jacketed variants with outgassing-certified materials (per ASTM E595).
How is connector cleanliness verified prior to shipment?
Every connector undergoes automated inspection using a 400× digital fiber scope (IEC 61300-3-35 compliant), followed by dry cleaning with Class 100 cleanroom-grade wipes and nitrogen purge. Inspection reports are included with each shipment.
