Product scope
This record is intended to describe bulk 24-fiber multimode indoor cable used to manufacture an MPO cable assembly. It is not, by itself, a finished MPO-to-MPO patch cord. Connector brand, ferrule format, gender, pinning, polarity, key orientation, polish, finished length and assembly-level insertion-loss or return-loss requirements are separate order fields.
The supplied record names a 3.5 ± 0.1 mm cable diameter, an aramid-yarn strength member and two proposed jacket selections. These values remain subject to BWNFiber Engineering review because the controlled datasheet, drawing and model/SKU were not supplied with this task.
Configuration status
| Field | Proposed value | Release status |
|---|---|---|
| Product role | Bulk cable for MPO assembly production | Supported by supplied V4 draft; confirm product owner |
| Fiber count | 24F | TBC — controlled source required |
| Fiber category | OM3, 50/125 µm | TBC — correct the conflicting grade table before release |
| Cable diameter | 3.5 ± 0.1 mm | TBC — controlled drawing/datasheet required |
| Strength member | Aramid yarn | TBC — construction drawing required |
| Jacket | Select one verified construction: LSZH material and/or an independently documented OFNR rating | TBC — do not present LSZH and OFNR as interchangeable labels |
| Reel packing | Proposed 1 km per roll | TBC — packing specification required |
| Product model / SKU | Not assigned | TBC — product owner required |
Blocked fiber-grade rows
The supplied V4 table includes an OM3-150 row with orange color, 950 MHz·km EMB and 150 m 10G reach. Those values conflict with the normal OM3 identification used by current manufacturer specifications, which show 2,000 MHz·km minimum EMB and 300 m 10 Gigabit Ethernet reach at 850 nm. do not use for order release either the OM3-150 name or its associated values until Engineering identifies the actual fiber grade and source row.
The proposed optical figures below are therefore retained only as review inputs, not as approved product claims:
| Proposed field | Supplied V4 value | Required action |
|---|---|---|
| Cabled attenuation | ≤3.5 dB/km at 850 nm; ≤1.5 dB/km at 1300 nm | Confirm test basis, source and applicable fiber grade |
| OM3 bandwidth | 2,000 MHz·km EMB at 850 nm; 1,500 MHz·km OFL at 850 nm | Confirm controlled fiber specification |
| 10GBASE-SR reach | 300 m | Confirm system assumptions and source; do not treat as a complete link guarantee |
| Standard reference | Supplied draft cites withdrawn ITU-T G.651 | Replace only after Engineering selects the correct current standard and product compliance evidence |
How to select the correct order configuration
- Confirm that the requirement is bulk cable stock for assembly production, not a connectorized trunk or patch cord.
- Specify 24 fibers and the controlled multimode grade from the approved fiber datasheet.
- Select the jacket material and state the exact building-code or fire-test evidence required by the destination project. Do not approve the cable from
LSZHorOFNRwording alone. - Confirm the finished cable diameter, tolerance and construction drawing against the connector boot, crimp, entry port and routing space.
- State the total cable length, length per roll, quantity, marking text, destination and required packaging.
- If BWNFiber will terminate the cable, provide the complete MPO build sheet separately: connector/ferrule, gender, pinning, polarity, key orientation, polish, finished length and assembly acceptance limits.
Application boundary
Use this product record only for the selected indoor bulk-cable construction and its approved assembly process. It does not establish:
- a finished MPO patch-cord configuration;
- compatibility with a specific transceiver, panel or connector brand;
- an OFNR, LSZH/FRNC, CPR, UL or other fire classification;
- installation, storage, tensile, crush or bend limits;
- connector insertion loss, return loss or a complete channel budget.
Each item above requires its own controlled source or project review.
For broad pathway and jacket selection, use the indoor fiber cable selection page. For connectorized products, compare the MPO/MTP breakout and fan-out cable range, the wider MPO connectivity category and the fiber patch cord category. These pages own the broader category or finished-assembly intent; P191 should remain the exact bulk-cable record.
Testing and quality-control requirements
TBC — source required. Before commercial approval, provide the controlled cable datasheet and drawing, fiber certificate or declaration, attenuation test method, dimensional inspection method, reel-length tolerance, jacket/rating evidence and acceptance criteria. If the cable is supplied as a finished MPO assembly, add the assembly test plan and traceable fiber-map, polarity, insertion-loss and return-loss records required by the approved build sheet.
Packaging and procurement information
The supplied draft proposes 1 km / roll. Confirm reel or roll type, maximum continuous length, length tolerance, label format, protective packing and shipping dimensions before publishing or quoting this value.
