## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TEL0155:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/TEL0155:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This is a single-mode dual-core fiber jumper with a wire diameter of 3mm and a wire length of 3m. Equipped with ceramic ferrule SC-type connectors and a protective shell, it features low insertion loss, good repeatability, good interchangeability, large return loss, tensile resistance, high performance, and durability. It also has stronger long-term pull tension and instant pull tension.

The fiber jumper is single mode which means the fiber enables one type of light mode to be propagated at a time, so it is more suitable for long-distance data transmission. And for the dual-core, it means that there are two single-core fibers. These optical fiber patch cords can be used in optical fiber communication systems, optical fiber access networks, optical fiber data transmission, and local area networks and other fields.
