LGX Cassette SC 1x8 PLC Splitter FTTH GPON

The LGX Cassette SC 1x8 PLC Splitter FTTH GPON represents a modular optical distribution solution engineered for high-density deployment in fiber-to-the-home (FTTH) and gigabit passive optical network (GPON) architectures. This passive component utilizes advanced Planar Lightwave Circuit (PLC) technology to evenly split a single optical input into 8 output channels, delivering consistent performance critical for bandwidth-intensive residential and business services.

Product Overview


Housed in a standard LGX cassette enclosure (29mm width x 100mm height x 158.5mm depth), this splitter integrates seamlessly into 19" and 21" rack-mounted LGX chassis systems, optimizing space utilization in central office and data center environments . The cassette design features SC UPC connectors on both input and output ports, ensuring reliable mating with standard optical distribution cables while maintaining low insertion loss characteristics.

Compliant with ITU-T G.671 and Telcordia GR-1209 standards, this splitter operates across the 1260nm to 1650nm wavelength range, supporting all current PON standards including GPON (ITU-T G.984), XG-PON (G.987), and XGS-PON. Each unit undergoes 100% factory testing for insertion loss, uniformity, and environmental stability, guaranteeing carrier-grade reliability in mission-critical networks .


Product Features


Superior Optical Performance

Insertion Loss ≤10.5dB (typical 9.5dB) at 1310nm/1550nm wavelengths, minimizing signal attenuation in PON distributions .

Splitting Uniformity ≤1.0dB across all 8 output channels, ensuring balanced bandwidth allocation to subscribers .

High Return Loss ≥55dB for input and output ports, reducing back reflections in sensitive GPON transceivers .


Modular LGX Design

Standard LGX Cassette Dimensions enabling hot-swappable installation in compatible chassis systems .

Front-Panel SC UPC Connectors with dust caps for easy access and protection during installation .

Integral Fiber Management with strain relief and cable retention features preventing microbend losses .


Environmental and Operational Stability

Wide Operating Temperature: -40°C to +85°C, suitable for both indoor and sheltered outdoor installations .

Humidity Resistance: Maintains performance at 95% RH (non-condensing) at 65°C for 1000 hours .

Vibration and Shock Compliance: Meets IEC 61753-1 Class B standards for harsh environment operation .


Applications


GPON Central Office Deployments

Primary distribution component in OLT (Optical Line Terminal) racks, splitting single OLT ports to serve up to 8 ONTs (Optical Network Terminals) in residential and business FTTH deployments. The LGX form factor enables high-density integration with OLT chassis systems.


MDU Fiber Distribution

Ideal for medium-sized multi-dwelling units (8-16 households), providing centralized fiber splitting in building entrance facilities. Supports symmetric 10Gbps services required for premium residential and small business applications.


Data Center Optical Distribution

Facilitates intra-data center fiber routing, splitting backbone links to connect multiple servers or storage arrays to core switches. The modular design simplifies network reconfiguration during capacity upgrades.


FTTH Distribution Hubs

Critical component in fiber distribution hubs (FDHs) located in neighborhood cabinets, extending optical signals from central offices to multiple residential streets. Supports both FTTB (fiber-to-the-building) and FTTH architectures.


Wireless Backhaul Networks

Enables fiber distribution to multiple 5G small cells from a central aggregation point, supporting the high-bandwidth backhaul requirements of 5G millimeter wave deployments.


FAQ


How does this LGX cassette splitter differ from ABS box splitters?

The LGX cassette design is optimized for rack-mounted central office environments with its standardized dimensions (29mm width) and hot-swappable capability, while ABS box splitters target outdoor/field installations. LGX versions support higher density integration (up to 14 cassettes in a 3U chassis) compared to discrete box splitters .


What PON standards does this splitter support?

It is fully compatible with GPON (1Gbps), XG-PON (10Gbps), XGS-PON (10Gbps symmetric), and NG-PON2 (25Gbps) standards. Its wide wavelength range (1260-1650nm) supports both upstream (1310nm) and downstream (1550nm) transmission bands used in these systems .


How many LGX cassettes can fit in a standard rack unit?

A 1U (1.75") rack space can accommodate up to 3 LGX cassettes (90mm total width), while a 2U chassis supports 6 cassettes. This high-density design reduces rack space requirements by up to 60% compared to traditional splitter configurations .


What is the typical service life of this PLC splitter?

When installed in protected environments, the splitter has an expected service life of 25+ years, meeting Telcordia GR-1221 requirements for passive optical components. The hermetically sealed LGX housing protects internal optics from dust and moisture degradation .


Can this splitter be used in reverse as a combiner?

Yes, it functions effectively as an 8x1 optical combiner for upstream signals in PON networks, combining signals from 8 ONTs onto a single fiber back to the OLT. Optical performance specifications remain identical in reverse operation, with no impact on reliability or signal quality.
