Passive optical distribution
Match splitter or WDM architecture to wavelength plan, ratio, package and insertion-loss targets.
A factory-connectorized butterfly drop cable for outdoor access links, available with one or both ends terminated to reduce field connector assembly.
Pre-Terminated Outdoor Butterfly Drop Cable combines a compact drop-cable structure with factory-installed connectors at one or both ends. It is intended for the access segment where crews need a defined cable length and connector arrangement before arriving on site, reducing field termination work while retaining the familiar flat drop-cable format.
The current construction uses high-carbon steel-wire strength members and a bend-capable fiber reinforcement. Published optical limits vary with assembly length and connector polish, so the final link budget must use the ordered length and end configuration rather than one generic patch-cord value.
Specify fiber grade and count, connector type and polish at each end, overall length, breakout length, pulling direction and the outdoor route conditions. Confirm whether the cable will be pulled through a duct, clipped to a façade or transitioned into an indoor pathway, because the installation method affects reinforcement and sheath review.
Huijue Group can review OEM, private-label and drawing-based assemblies with project-specific length, connector mapping and packaging. A customer sample may be used to confirm the mating interface. Cable construction, connector performance, pull protection, test report scope, quantity and tooling remain subject to engineering approval.
Optical Performance Requirements for Pre-Terminated Butterfly Drop Cable
| Serial No. | Test Item | L ≤ 20m | 20m < L ≤ 50m | 50m < L ≤ 100m | 100m < L ≤ 200m |
| a | Insertion Loss (1310nm)¹ | ≤ 0.3dB | ≤ 0.34dB | ||
| b | Insertion Loss (1550nm)² | ≤ 0.3dB | ≤ 0.32dB | ||
| c | Return Loss (UPC)³ | ≥ 47dB | ≥ 46dB | ≥ 45dB | ≥ 44dB |
| d | Return Loss (APC)⁴ | ≥ 55dB | ≥ 51dB | ≥ 49dB | ≥ 46dB |
¹ Insertion Loss (1310nm wavelength) for pre-terminated butterfly drop cable with L > 200m: 0.30dB + L×0.36dB/1000m
² Insertion Loss (1550nm wavelength) for pre-terminated butterfly drop cable with L > 200m: 0.30dB + L×0.22dB/1000m
³ Return Loss (UPC) for pre-terminated butterfly drop cable with L > 200m: ≥ 40dB
⁴ Return Loss (APC) for pre-terminated butterfly drop cable with L > 200m: ≥ 40dB
Route exposure, bend radius, pulling load, water entry and the indoor transition point must be reviewed for the actual site. Use sealing and mechanical protection appropriate to the enclosure and pathway; no enclosure protection rating is implied for the connectorized cable assembly.
Buyer Questions
Answers specific to Pre-Terminated Outdoor Butterfly Drop Cable selection, configuration and purchasing.
Yes. The source describes one-end or two-end factory termination; specify which end must remain unterminated for pulling or splicing.
The current performance table uses different limits by length, so the ordered assembly length and polish must be included in the review.
Huijue Group can review a customer sample or drawing, with final compatibility and production feasibility confirmed before manufacture.
Use the deployment context to narrow the configuration before comparing dimensions, capacities and options.
Match splitter or WDM architecture to wavelength plan, ratio, package and insertion-loss targets.
Coordinate connector, polish, fiber grade, polarity and cable length across patching points.
Plan MPO/MTP trunks and harnesses around port mapping, breakout format and rack density.
Select splicing, cleaning and test tools for the connector types and measurements used on site.
Before quotation: confirm capacity, interfaces, installation environment, power conditions, quantity and required options.
