A compact indoor butterfly drop cable with factory-installed connectors at one or both ends for planned FTTH and in-building access routes.
Pre-Terminated Indoor Butterfly Drop Cable is a factory-assembled last-drop cable for indoor access routes. By defining the connector ends and cable length before production, installers can connect subscriber or distribution equipment without performing every connector termination inside the building.
The listed construction uses a compact butterfly profile, bend-capable reinforcement and a low-smoke, halogen-free sheath. Optical limits in the current data are organized by assembly length and UPC or APC return-loss requirement, making accurate route measurement an important ordering step.
Confirm the route length with service allowance, fiber grade, connector type, UPC or APC polish, termination direction and whether one end must pass through a duct or wall opening. Also define the required jacket marking and packaging so assemblies can be identified at installation.
Huijue Group can assess private-label or OEM indoor drop assemblies from an approved cable schedule, end-face map or physical sample. Custom length, connector combination and labeling are reviewed together; tolerance, test method, packaging, tooling and order quantity require confirmation.

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
Use the cable in an indoor pathway compatible with its LSZH construction. Maintain the specified bend radius, protect connector ends during pulling and provide a suitable transition if any section becomes exposed outdoors.
Buyer Questions
Answers specific to Pre-Terminated Indoor Butterfly Drop Cable selection, configuration and purchasing.
It reduces field connector assembly when the route, end interfaces and length are known before installation.
A mixed end configuration can be reviewed from the end-to-end schedule, but the connector types and mating equipment must be explicitly confirmed.
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.
