Product Structure & Composition
Optical Splitting Core: The splitter’s core is a PLC-based optical splitter that evenly divides the input signal from one port into four outputs, ensuring consistent, low-loss signal distribution across all channels.
LGX Cassette Enclosure: This compact LGX cassette houses the splitting core, fits standard patch panels and enclosures, saves space, and protects internal components from physical damage, dust, and environmental factors.
Connectors and Pigtails: Default SC/APC connectors with 2.0mm pigtails (single-mode G652D or G657A) reduce back-reflection via APC polish, improving return loss. Other connector types (LC, FC, ST) and polish options (UPC or APC) are available upon request.
Benefits of 1×4 LGX Cassette Fiber Optic Splitter
Balanced Signal Distribution
The 1x4 splitter design ensures that the optical signal is evenly distributed among the four output channels. This balanced distribution is essential for applications where each output needs to receive a consistent optical signal, such as in FTTH systems where multiple households are served from a single optical source.
Space - saving in Compact Enclosure
The LGX cassette design is highly space - efficient. In FTTH and PON systems, where space in distribution cabinets or wall - mounted enclosures is often limited, the compact LGX cassette can be easily installed in a standard patch panel, optimizing the use of available space and simplifying the cabling process.
Fiber Compatibility for Long - distance Transmission
Compatibility with G652D and G657A single - mode fibers makes the splitter suitable for long - distance transmission applications. These fiber types are known for their low - loss characteristics over long distances, and the splitter's ability to work with them ensures efficient signal distribution over extended network spans.

1×4 LGX Cassette Fiber Optic Splitter Selection Guide
Choose the 1×4 LGX Cassette PLC Splitter when:
Deploying in indoor structured cabling environments such as central offices, data centers, or telecom equipment rooms with 19-inch racks or ODF frames.
Requiring front-panel access for easy patching, testing, and reconfiguration.
Needing hot-swappable modules that can be replaced or upgraded without disrupting adjacent fibers or cables.
Managing high-density rack installations where standardized, professional cable management is critical.
Working in environments where maintenance and scalability are top priorities.
Choose the 1×4 ABS Module PLC Splitter when:
Deploying in outdoor FTTH distribution – pole-mounted FAT boxes, FDB enclosures, or CTO terminals.
Space is limited in compact outdoor enclosures where a small plastic module is easier to fit.
Installation requires flexible, versatile mounting options with tie-points or screw holes.
The deployment is in rural ODN or drop-level distribution where rack compatibility is not needed.
Budget is constrained – ABS modules typically cost less than metal LGX cassettes.
Mixed deployment strategy:
Use LGX cassettes in the central office or data center headend for professional rack-based management, and ABS modules in the field at distribution points, pole-mounted cabinets, or outdoor FDB enclosures. This leverages the strengths of each format: rack-based modularity indoors, and compact, weather-resistant packaging outdoors.
Key decision factors:
| Factor | LGX Cassette | ABS Module |
|---|---|---|
| Best for | Indoor racks, ODF, data centers | Outdoor FTTH, FAT/FDB/CTO boxes |
| Mounting | Slides into 19″ racks or LGX enclosures | Tie-points, screws, or adhesive |
| Density | Lower per rack unit (larger footprint) | Higher (compact size) |
| Maintenance | Hot-swappable, front access | Requires opening enclosure |
| Cost | Higher | Lower |
| Environmental | Indoor, controlled climate | Outdoor, weather-resistant housing |
Installation Instructions of 1×4 LGX Cassette Fiber Optic Splitter
Pre‑installation Inspection
Check the LGX cassette for damage; ensure SC/APC connectors are clean and pigtails are intact. Verify port labeling is clear.
Installation in the Enclosure
Insert the cassette into the patch panel slot, align properly, and secure it (screws or locking mechanism if needed).
Fiber Connection
Connect the input fiber (G652D/G657A) to the input port; align the SC/APC key and push until it locks. Connect output fibers to the four ports and label each clearly.
Testing
Measure insertion loss at each output port with an optical power meter. If values exceed specification, re‑clean connectors, check connections, and inspect the splitter. Also verify return loss meets standards.

Factory Real Shot
State-of-the-Art Manufacturing Facilities
Our 60,000 sqm dust-proof workshop houses over 21+ automated production lines for single-core and MPO patch cords. Equipment includes high-precision fiber cutters (±0.08 mm tolerance), FLC automatic termination machines, and UV curing systems, enabling a daily output of thousands of connectors with consistent quality.
Precision Core Manufacturing Process
The process starts with micro-tolerance cutting (end-face angle ±0.5°) and six-axis fusion splicing (core deviation ≤1 μm). After multilayer jacketing with LSZH, PVC, or OFNP, connectors are polished on automated lines for PC, UPC, or APC finishes, achieving up to 7,000 connectors per 11-hour shift.
Rigorous Quality Assurance & Testing
Every patch cord undergoes 100% inspection: interferometric end-face analysis (400x), automatic contamination detection, and insertion/return loss testing via OTDR. Environmental samples also pass temperature, humidity, and pull-force tests per IEC/TIA standards.

Q5: Is OEM customization supported?
A5: Absolutely. We support OEM/ODM and can tailor connector type, fiber length, polish, and packaging as needed.
Why are SC/APC connectors the default for this splitter?
SC/APC connectors are the default because APC polish provides high return loss, which is beneficial in reducing signal reflections. In optical networks, minimizing signal reflections helps maintain the quality and reliability of the optical signal across the output channels. Also, SC connectors are widely used in the fiber - optic industry, making integration into existing FTTH and PON systems relatively easy.
Can the 1×4 PLC fiber optic splitter LGX cassette be used for outdoor applications?
The 1×4 PLC fiber optic splitter LGX cassette is primarily designed for indoor use within the protected environment of distribution cabinets or patch panels. While it can be used in some sheltered outdoor enclosures, for fully exposed outdoor applications, it may require additional protection. Outdoor environments expose the splitter to harsh weather conditions, UV radiation, and mechanical stress, which could affect its performance and durability.
