2×64 Cassette PLC Splitter Overview
The BWN-PLC-CT-2X64-SC-APC-2.0 is the density ceiling of the cassette PLC family: a dual-input 2×64 planar splitter in one protected ABS module — two input ports, 64 outputs per path, 128 SC/APC-terminated ports in a single cassette. One module can run two PON services to the same 64-drop branch, or a main and standby feed, without a second splitter position.
That density comes with discipline. Published insertion loss for the 2×64 is 21.0dB with a 2.2dB-class uniformity window — the widest in the family. At this level the splitter alone consumes most of a GPON Class B+ budget (28dB); 2×64 builds typically assume higher-budget optics (Class C+) and a clean, short distribution plant. Verify the budget before the purchase order, not after. Family overview: cassette PLC splitter category.
Key Features
- 128 ports in one cassette: two independent inputs, each split to 64 SC/APC outputs.
- Dual-service or redundant-feed ready: GPON + XGS-PON coexistence or main/standby architectures in a single module.
- Protected cassette format: ABS module for street cabinets, distribution boxes and high-density ODF panels.
- Planar flatness: the 1260–1650nm band covers GPON, XGS-PON and NG-PON2 wavelength plans.
- Wide temperature rating: -40°C to +85°C operating and storage.
- Configurable at order: 1m / 2.0mm pigtails standard; 0.9mm, 3.0mm and custom lengths available.

Connectors, Fiber Types & Compatibility
This model ships with SC/APC on both inputs and all 64 outputs per path. Fiber is G657A bend-insensitive singlemode standard; customer-specified fiber available. The 2.0mm jacketed pigtails (1m standard; 0.9mm and 3.0mm options) mate with SC adapter fields in cabinets, fiber distribution boxes and ODF frames.
At 128 ports per module, confirm the enclosure has the adapter capacity and slack management for two 64-port fields before ordering. The cassette is a protected component, not a sealed outdoor device.
Applications
- Maximum-density FTTH distribution: 64 drops per service from a single cassette position.
- GPON + XGS-PON coexistence at scale: two services on one passive branch without rebuilding the distribution point.
- High-availability branches: main/standby feeders into the same 64 outputs.
- Centralized-split ODN architectures: where the design consolidates splitting at one cabinet instead of cascading across the field.
How to Choose the Right Configuration
1. Budget gate first: 21.0dB IL + 2.2dB uniformity + fiber/connectors must fit your PON class budget. If the margin is thin, step down to 2×32 (17.5dB) or a 1×64 single-input. The splitter loss chart maps the ratios.
2. One service or two? One → 1×64. Two services or redundancy → this 2×64.
3. Topology: centralized 2×64 suits concentrated drops; geographically spread drops may be better served by cascaded smaller splits.
4. Polish and plant: APC end to end; confirm the distribution plant is SC/APC throughout.
5. Enclosure capacity: verify adapter count and slack management for 128 ports before specifying.

Testing & Quality Control
A 2×64 acceptance means 128 per-port IL measurements (two paths × 64 ports), plus the uniformity window and per-port RL. At a 2.2dB uniformity class, the worst port — not the average — decides whether the furthest subscriber syncs; insist on per-port records for project orders. The published characterization for this series is stated to Telcordia GR-1209-CORE / GR-1221-CORE generic requirements; share your acceptance criteria and we align shipment documentation accordingly.
