Scope
Use this Family for fiber harnesses that fan a trunk interface into multiple legs. Exact leg mapping and polarity must be explicit.
Request preparation
Share trunk and breakout connectors, gender, polarity, fiber type, trunk and leg lengths, labeling scheme, quantity, and deployment context.
Technical parameters and selection boundaries
Published configurations differ by manufacturer and exact part number. These are selection dimensions, not one combined specification.
| Parameter | Documented example or choice | Verify for this request |
|---|---|---|
| Named construction | QSFPTEK 103108 is described as a 4 m, 12-fiber OM4 MPO-12 female to six duplex LC breakout assembly. | The page title and product photograph describe MPO-to-LC; one connector-table entry disagrees. Confirm the final assembly drawing and connector list before ordering. |
| Jacket and finish | LSZH jacket; UPC-to-UPC polish; listed polarity Type B. | Confirm pin gender and the end-to-end lane map separately. Jacket color alone does not establish optical grade. |
| Cable mechanics | 3.0 mm listed diameter; minimum cable bend radius 20D dynamic / 10D static; tensile limit 80 N long-term / 150 N short-term. | D refers to cable diameter. The separate 7.5 mm fiber-core value must not replace the installed cable bend limit. |
| Optical table limits | The product page lists insertion loss ≤0.35 dB and return loss ≥30 dB. | The excerpt does not fully define each measurement plane. Request the individual assembly test report and budget the complete channel. |
| Temperature | Operation −10 to +70 °C; storage −40 to +85 °C for the named page example. | These are separate operating and storage limits, not a guarantee for every OM4 harness. |
| Fiber attenuation | Listed maximum attenuation: 2.3 dB/km at 850 nm and 0.6 dB/km at 1300 nm. | Attenuation per kilometer is not the insertion loss of a finished short breakout. |
Standard configurations and project options
| Configuration area | Documented option | Project decision |
|---|---|---|
| Ordered branch layout | Specify total length, branch lengths, numbered LC legs, pin gender, polarity and jacket grade. | The 4 m example is one configuration. Do not assume every leg is active in a four-channel parallel-optics application or infer host breakout support from fiber count. |
| Optical acceptance | Define the required insertion-loss limit, return-loss limit and test wavelengths for the selected assembly. | Use the specified optical budget and per-assembly result; do not mix a fiber attenuation figure with connector or finished-assembly loss. |
Representative models and configurations
Examples illustrate real product variation. A listed manufacturer or model is not a statement of our stock, authorization, or confirmed availability.
| Manufacturer / series | Published configuration | Important scope |
|---|---|---|
| QSFPTEK 103108 | 4 m; 12 fibers; OM4; MPO-12 female to six duplex LC; Type B; LSZH. | Representative brand listing with a flagged connector-table inconsistency. Obtain the exact drawing and test report; no stock or commercial relationship is implied. |
Applications and procurement context
- Use a defined MPO-to-LC harness for the matching parallel-optics or structured cabling layout. Check the host breakout mode, optical interface, active fiber positions and branch labels before treating it as a working link.
Compatibility, current supply, lead time, origin, and acceptance documents must be confirmed for the actual order.
