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. For ratio selection, budget math and deployment architectures at this split level, see the 1×64 fiber optic splitter specs and deployment guide. Family overview: cassette PLC splitter category.
Key Features
- Single-stage 1:64 split: this 1×64 PON splitter serves 64 drops from one PON port 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; it is 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.
The output-side density is the practical reason for the hybrid. Panel geometry is the constraint at 64 ports: a 1U 19-inch panel typically accommodates on the order of 24 SC duplex adapters, while the same space takes roughly double that in LC duplex. Terminating 64 outputs on LC keeps the adapter field to about one panel position instead of two or three, and keeps patch-cord routing inside the cabinet manageable. If your distribution side is already SC-standardized, that density argument disappears — the all-SC sibling below is then the cleaner build.
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. This is the classic 64-way GPON split point.
- 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.
BWN-PLC-CT-1X64-APC vs the All-SC/APC 1×64 and the Rack-Mount 1×64
Three BWNFiber pages serve the 1×64 ratio, and they are not interchangeable. This page is the hybrid cassette: SC/APC in, LC/APC out, for cabinet and dense-panel builds. If your outside plant and distribution side are both SC/APC, the all-SC cassette avoids a connector transition. If the splitter lives in a 19-inch frame rather than a cabinet or box, the 1U rack-mount is the right housing.

|---|---|---|---|---|
| This page: 1×64 cassette SC→LC | SC/APC in → LC/APC out | ABS cassette | 20.5/21.0dB | Max split + dense LC output fields |
| 1×64 cassette SC/APC 3.0 | SC/APC throughout | ABS cassette | 20.5/21.0dB | Max split, all-SC plant |
| 1×64 rack-mount 19″ 1U | SC/APC on front panel | 19″ 1U chassis | See rack datasheet | CO/ODF frame installations |

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.
