Product Structure & Composition
Optical Splitting Core: At the heart of the splitter is the Planar Lightwave Circuit (PLC) - based optical splitting core. This core is engineered to evenly divide the incoming optical signal from the single input port into eight output ports. The PLC technology ensures precise and consistent signal splitting, maintaining the integrity of the optical signal across all output channels.
Steel Tubular Mini - module: The steel tubular mini - module encases the optical splitting core. It provides robust mechanical protection, safeguarding the delicate internal components from physical impacts, vibrations, and other mechanical stresses. The compact design of the module also helps in saving space within network enclosures.
SC/UPC Connectors: The splitter is equipped with SC connectors featuring UPC (Ultra - Physical Contact) polish. The SC connectors offer a secure and easy - to - use connection interface. The UPC polish on the ferrules ensures a low - loss and high - quality optical connection when mated with other fiber optic components.
Benefits of 1x8 PLC Fiber Optic Splitter
High - density Splitting for Various Networks
The 1x8 configuration is highly versatile, catering to different network types. In telecom networks, it can be used to distribute optical signals to multiple subscribers or network nodes. In LANs, it helps in expanding the connectivity to various devices such as computers, servers, and printers. In data centers, it can be utilized for efficient signal distribution within the high - density cabling infrastructure.
Enhanced Protection and Space - saving
The steel tubular mini - module not only provides excellent protection to the internal optical components but also occupies minimal space. In crowded network enclosures like data center racks or telecom cabinets, this space - saving design allows for more efficient use of available space, enabling the installation of multiple splitters without overcrowding.
Superior Signal Quality
With low insertion loss and high return loss, the splitter ensures that the optical signals are transmitted with minimal degradation. Low insertion loss means that the signal loses very little power as it passes through the splitter, while high return loss prevents signal reflections that could disrupt the overall signal quality. This results in reliable and high - quality data transmission across the split paths.
Seamless Network Integration
The SC/UPC connectors enable easy integration into existing network systems. Since SC connectors are widely used in the industry, the splitter can be quickly and easily connected to other network devices such as patch panels, optical transceivers, and switches, reducing the need for additional adapters or complex installation procedures.
Engineering Applications 1x8 PLC Fiber Optic Splitter
Widely Used in FTTX Projects and Data Communication Centers
Optical splitter has played an important role in passive optical networks (like EPON, GPON, BPON, FTTX, FTTH, etc.) by allowing a single PON Interface to be shared among many subscribers.
FTTH Floor Distribution
In residential buildings, the 1×8 splitter serves as a secondary node in the corridor cabinet, splitting one OLT signal to 8 homes. With ~10.5 dB loss, it supports drop cables up to 5 km, and its compact package simplifies fusion splicing while reducing termination density.
5G CRAN Fronthaul
Paired with CWDM/LWDM, the splitter fans one DU port to 8 AAUs over a single fiber. It requires low PDL (<0.3 dB) and good uniformity to meet 25G eCPRI sync needs, cutting trunk cores from 16 to just 2 per site.
Data‑Center Link Monitoring & APS
Inserted in‑line on the primary link, one output carries traffic while seven feed monitors (power, OTDR) for real‑time diagnostics. A low‑loss (≤11 dB) 1U module enables 50 ms protection switching, replacing cascaded couplers and reducing failure points.

1x8 PLC Fiber Optic Splitter Selection Guide
Choose the 1×8 PLC Splitter when:
Deploying modern PON networks (EPON, GPON, XGS-PON) requiring consistent, equal power distribution across all 8 output ports.
Operating across the full 1260-1650 nm wavelength range for maximum flexibility in multi-wavelength applications.
Deploying in environments with wide temperature variations (-40 to 85°c).
Requiring compact form factor for high-density enclosures, cabinets, or ODFs.
Prioritizing long-term reliability and low failure rates.
Choose the 1×8 FBT Coupler only when:
A custom, non-standard split ratio is required (e.g., 1×3. 1×5. 1×7) that PLC cannot provide.
The application is a small network or short-distance deployment where uniformity and wide temperature range are less critical.
Budget is extremely constrained for very small split ratios (1×2. 1×4).
Working with legacy systems that only support specific wavelengths (850nm, 1310nm, 1550nm).
Note: For 1×8 splitting, FBT is generally not recommended due to cascaded construction (7 × 1×2 couplers + 6 splices), resulting in higher insertion loss (10.8 dB vs. 9.8 dB), poorer uniformity (up to 3 dB), higher TDL/PDL, larger size, and increased failure risk. The cost advantage of FBT diminishes at higher split ratios.
Choose the 1×4 PLC Splitter when:
The application only requires 4 output ports - fewer outputs mean lower insertion loss (~7.2 dB) and lower cost than 1×8 PLC.
Subscriber density is low (e.g., small MDUs, rural deployments, or office buildings).
Future expansion to 1×8 is not anticipated - using a smaller splitter now avoids unnecessary loss and cost.
Split ratio guidance:
1×2 - 1×4: Both PLC and FBT are viable; FBT may offer lower cost for custom ratios.
1×8: PLC is strongly recommended for performance and reliability.
1×16 - 1×64: PLC is the only practical choice - FBT cannot maintain acceptable uniformity or loss.
Installation Instructions of 1x8 PLC fiber optic splitter
Visually inspect the splitter for damage, clean connectors, and check port labels. Connect the input fiber (G652D/G657A) and the eight output fibers, ensuring firm insertion and clear labeling. Mount the splitter securely in the patch panel or enclosure without straining the fibers. Finally, measure insertion loss at each output port; if readings are too high, re‑clean connectors and inspect for internal damage. Also verify that return loss meets the specified standards.

What is the difference between UPC and other types of connector polish?
UPC (Ultra - Physical Contact) polish provides a highly polished, flat - ended ferrule surface. This design results in low insertion loss, making it suitable for general - purpose optical connections. In contrast, APC (Angled Physical Contact) polish has an angled ferrule surface (usually 8°), which is designed to reduce back - reflection and is used in applications where high return loss is crucial, such as long - distance or high - performance optical links.
Can the 1x8 PLC fiber optic splitter be used with multimode fiber?
No, this splitter is designed specifically for use with single - mode fibers G652D and G657A. Multimode fibers have different optical characteristics, and using them with this splitter may lead to poor signal performance, high insertion loss, and unreliable data transmission. For multimode applications, a splitter designed for multimode fibers should be used.
