1×64 Cassette PLC Splitter Overview (SC/APC to LC/APC)
The BWN-PLC-CT-1X64-APC is the highest-ratio member of the cassette PLC family: one input split sixty-four ways in a single protected ABS module. Its defining detail is the hybrid interface — a rugged SC/APC 3.0mm pigtail on the feeder side, sixty-four LC/APC 2.0mm pigtails on the distribution side. The feeder leg gets the connector and cable construction that survives cabinet handling; the output side gets the density that 64 ports demand.
Published insertion loss for the 1×64 is 20.5/21.0dB (P/S grade) with 2.0dB-class uniformity, flat across the 1260–1650nm band. That number deserves respect in the link budget — a 1×64 split consumes most of a GPON Class B+ budget (28dB) once fiber and connectors are added, which is why many 1×64 builds specify higher-budget optics such as Class C+. Plan the budget first; the splitter does not forgive an optimistic one. Family overview: cassette PLC splitter category.
Key Features
- Single-stage 1:64 split: one PON input serves 64 drops without a cascaded second stage.
- Hybrid SC→LC interface: SC/APC 3.0mm feeder pigtail for robust handling; 64 × LC/APC 2.0mm outputs for dense adapter fields.
- Protected cassette format: ABS module for street cabinets, distribution boxes and ODF panels — the format cabinet splitter modules have made the norm for 1×64 builds.
- Planar wavelength flatness: the 1260–1650nm band covers GPON, XGS-PON and NG-PON2 wavelengths.
- Wide temperature rating: -40°C to +85°C operating and storage.
- Configurable at order: pigtail lengths and fiber type (G657A standard) confirmed on the datasheet before production.

Connectors, Fiber Types & Compatibility
The input is SC/APC on a 3.0mm jacketed feeder pigtail — the robust end, sized for cabinet feeder handling. The outputs are 64 × LC/APC on 2.0mm pigtails — the dense end, matched to LC adapter fields on high-density ODF frames and splitter panels.
Fiber is G657A bend-insensitive singlemode standard; customer-specified fiber available. One plant check before specifying this hybrid: LC/APC on the output side presumes LC adapter infrastructure downstream — confirm the distribution-side connector standard first.
Applications
- Maximum-coverage FTTH distribution: one PON port serves 64 subscribers from a single cabinet cassette.
- Street cabinet and cross-connect builds: the protected module format matches cabinet installation practice for high-ratio splits.
- High-density ODF and CO splits: the LC output side keeps 64 ports within dense panel space.
- PON coexistence builds: the 1260–1650nm window carries GPON today and XGS-PON on upgrade without touching the passive layer.
How to Choose the Right Configuration
1. Budget first: at 20.5/21.0dB IL, a 1×64 split leaves limited margin — verify your PON class (B+ / C+) and total fiber/connector budget before choosing 1×64 over 1×32. The splitter loss chart maps the ratios.
2. Ratio vs topology: if drops are geographically grouped, a cascaded 1×8 × 1×8 design may serve better than one 1×64 point; if distribution is concentrated, single-stage wins on connector count and simplicity.
3. Interface: this hybrid (SC in → LC out) suits feeder-to-dense-panel builds; if both sides are SC, see the 1×64 SC/APC 3.0 sibling.
4. Package: cassette for cabinets and boxes; rack-mounted or LGX formats for 19-inch frames; steel-tube for splice-in builds.
5. Pigtails: input 3.0mm / output 2.0mm as modeled; custom lengths on request.

Testing & Quality Control
At 1×64, per-port uniformity matters as much as headline IL: a 2.0dB-class uniformity window means the worst port can sit about 2dB above the best. Acceptance testing should record per-port IL and RL, not just a sample port. The published characterization for this series is stated to Telcordia GR-1209-CORE / GR-1221-CORE generic requirements; for project orders, share your acceptance criteria and we align shipment documentation accordingly.
