Product Structure & Composition
Optical Splitting Core: The PLC-based core splits the input signal from one port into two outputs with consistent accuracy and signal integrity.
LGX Cassette Housing: This compact cassette protects the core, fits standard racks/panels for seamless integration, and shields against dust and physical damage.
Connectors and Pigtail: Default SC/APC with 2.0mm single-mode pigtail (G652D/G657A) reduces back-reflection for high return loss; other connector types (LC, FC, ST) and polish options (UPC/APC) are available on request.
Benefits of 1x2 LGX Cassette Fiber Splitter
Ideal for Point - to - Point Distribution
The 1x2 split ratio is highly effective for point - to - point optical distribution. In scenarios where an optical signal needs to be directed to two specific endpoints, such as connecting a central office to two remote nodes in a telecom network or splitting the signal to two different devices in a local area network, this splitter ensures precise and efficient signal distribution.
Compact and Space - saving Integration
The LGX cassette housing allows for easy and space - saving integration into racks or panels. In data centers, telecom central offices, or other network installations where space is at a premium, the compact size of the LGX cassette enables more efficient use of available space. It can be neatly installed in a standard rack or panel, reducing clutter and facilitating better cable management.
Connector and Polish Customization
The availability of different connector types and polish options provides flexibility in network deployment. Whether the existing network infrastructure uses LC - based high - density cabling, FC connectors for high - performance connections, or ST connectors for quick - connect applications, the splitter can be customized to meet these requirements. The choice between UPC and APC polish also allows for optimization of signal performance based on the specific application needs.
Excellent Optical Performance
With low insertion loss and high return loss, the splitter ensures high - quality optical signal distribution. Low insertion loss means that the optical signal loses minimal power as it passes through the splitter, while high return loss prevents signal reflections that could disrupt the overall signal quality. This results in stable and reliable data transmission across the two split paths.
Engineering Applications 1x2 LGX Cassette Fiber Splitter
In central offices and FTTx networks
the 1x2 LGX cassette splitter distributes a single OLT signal to two subscribers or feeder paths with low insertion loss and excellent uniformity. Its standard LGX footprint allows quick installation in 19″ shelves, supporting EPON, GPON, and XG-PON across the 1260–1650 nm band, making it a compact first‑stage splitting solution for greenfield and upgrade projects.
In data centers and enterprise LANs
this splitter enables signal duplication for active monitoring, load balancing, or dual‑path redundancy. The plug‑and‑play cassette saves rack space, and front‑panel access permits fast reconfiguration without disturbing adjacent fibers, reducing downtime and maintenance costs in high‑density environments.
For CATV headends and private corporate networks
the splitter evenly distributes broadcast video or centralized services to multiple areas or backup receivers. High return loss and low PDL ensure signal integrity, while Telcordia‑compliant construction guarantees reliability in campus, hospital, and banking installations where uninterrupted service is critical.
In field testing and network surveillance
the splitter taps a small portion of live optical power for performance analysis or troubleshooting without service interruption. The rugged metal cassette withstands temperatures from -40°C to 85°C, suiting both indoor equipment rooms and outdoor cabinets, and serves as either a permanent network element or a portable test fixture for carrier‑grade maintenance.

1x2 LGX Cassette Fiber Splitter Selection Guide
Choose the 1×2 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 1×2 ABS Box 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
Pre-installation Inspection
Visually check the cassette for damage, ensure the SC/APC connector and ferrule are clean and debris‑free, verify the pigtail has no kinks or cuts, and confirm port labels are clear.
Installation in the Rack or Panel
Insert the cassette into an available slot, align it properly, and secure it with screws or locking mechanisms if required.
Fiber Connection
Connect the input fiber (SC/APC) to the input port, then connect the two output fibers to their respective ports. Label all connections clearly for future maintenance.
Testing
Measure insertion loss at each output with an optical power meter and compare to specifications. If values are too high, re‑check connections, clean connectors, and inspect for damage. Also verify return loss meets standards.

A5: We offer a 2-year warranty, 3-month free return for quality issues, and OEM/ODM customization of connectors, polishing, and fiber lengths.
What is the significance of the APC polish in the default SC/APC connector?
The APC (Angled Physical Contact) polish in the SC/APC connector is significant because it helps to reduce back - reflection of the optical signal. In optical networks, back - reflection can cause signal degradation and interference. By reducing back - reflection, the APC polish improves the return loss of the connection, ensuring a more stable and reliable optical signal transmission. This is especially important in long - distance or high - performance optical links.
Can the 1x2 LGX cassette fiber splitter be used in a high - humidity environment?
The 1x2 LGX cassette fiber splitter is designed to operate in normal indoor environments. In high - humidity environments, additional protective measures may be required. High humidity can potentially cause moisture ingress into the splitter, which could affect the performance of the optical components. It is advisable to install the splitter in a well - ventilated and moisture - controlled enclosure or use a splitter with enhanced moisture - resistant features if it is to be used in a high - humidity environment.
