Key Features
LGX-Compatible Cassette Design
The 120mm wide form factor adheres to the industry-standard LGX footprint, allowing direct insertion into LGX adapter panels, fiber distribution hubs, and splice enclosures without custom mounting hardware.
- Snap-in installation with positive latching provides secure retention
- Tool-free removal for maintenance or reconfiguration
- Compact 18mm height permits high-density vertical stacking-up to 24 units in a single 1U rack space
Factory-Terminated SC/APC Connectors
Both input and all 32 output ports arrive pre-installed with SC/APC (angled physical contact) connectors, featuring factory-polished 8-degree angled endfaces that deliver ≥55 dB return loss performance.
- Eliminates back-reflection issues that degrade optical signal-to-noise ratios
- Reduces deployment defect rates from 3–5% (field splicing) to <0.1% (factory termination)
- Accelerates deployment schedules by 60–80% compared to splice-based installations
G.657A1 Bend-Insensitive Singlemode Fiber
Input and output pigtails utilize G.657A1 fiber optimized for tight-radius routing in congested cabinets and cable trays, maintaining low attenuation even when bent to 10mm radius.
- 2.0mm jacketed construction provides crush resistance up to 100N/cm
- Pull strength exceeding 60N protects the 9/125μm singlemode core
- Standard 1.5-meter pigtail length accommodates typical cabinet depths
Wide Wavelength and Temperature Range
The splitter operates across the extended O-band through L-band spectrum (1260–1650 nm) with <0.5 dB wavelength-dependent loss, ensuring equal performance for all PON wavelengths.
- Temperature-dependent loss remains below 0.5 dB across -40 to +85°C
- Hermetically sealed PLC chip resists humidity, condensation, and salt-fog corrosion
- Suitable for deployment in outdoor cabinets subject to extreme temperature swings
Uniform Power Distribution and Low PDL
Insertion loss uniformity of ≤1.5 dB across all 32 outputs ensures predictable link budgets regardless of which output port connects to a given subscriber.
- Eliminates the need for per-port power adjustment at the OLT
- Polarization-dependent loss below 0.3 dB prevents signal fading in coherent detection schemes
- Supports multi-rate PON systems from 1.25 Gbps EPON to 10 Gbps XG-PON and future 25–50 Gbps coherent PON
Robust ABS Module Housing
The splitter mounts within a flame-retardant ABS thermoplastic cassette rated to UL94 V-0 for ignition resistance-essential for enclosed rack environments.
- Shields the PLC chip from mechanical shock (tested to 50G half-sine pulse)
- Protects against vibration (10–55 Hz sweep) during shipping and seismic events
- Molded strain relief boots prevent kinking at fiber exit points
Flexible Customization for Your Projects
Split Ratio Configuration
While this page features the 1×32 model, we manufacture the complete range including 1×2, 1×4, 1×8, 1×16, 1×32, and 1×64 for single-input architectures, as well as 2×2, 2×4, 2×8, 2×16, 2×32, and 2×64 dual-input configurations for redundant or dual-feed designs.
Connector Type Selection
Beyond the standard SC/APC shown here, we provide SC/UPC, LC/APC, LC/UPC, and other connector interfaces to match your existing infrastructure and patch panel standards.
Fiber Type and Specifications
Choose from G.652D standard singlemode fiber for long-haul applications, G.657A1 for moderate bend-insensitivity, or G.657A2 for ultra-tight routing scenarios.
Cable Length and Jacket Diameter
Input and output fiber pigtails are customizable from 0.5m to 3m or longer for specific cabinet depths and routing paths.
Labeling and Identification
Custom port numbering schemes, color-coded connectors and boots, laser-marked labels with your part numbers, and sequential serial number tracking can be implemented.
Packaging Form Factor
While the LGX box format is highlighted here, we produce PLC splitters in various packaging options based on mounting environment and density requirements.
