Is a fiber optic patch cord just a 2m cable Why
A fiber patch cord—also known as a fiber optic patch cable—is a short, flexible cable, typically 1 to 10 meters long, used to connect two devices in a network. These connectors, commonly SC, LC, or ST types, facilitate the connection between optical devices such as transceivers, switches, and routers. As data rates increase from 10G → 100G → 400G → 800G, patch cables must handle more bandwidth, more density, and stricter. A fiber-optic patch cord is a fiber-optic cable capped at each end with connectors that allow it to be rapidly and conveniently connected to telecommunication equipment.

Why does the pigtail have two hairs
The term "pigtails" actually has historical roots. Over time, it became associated with the hairstyle involving two sections. Pigtails (or twin tail or twintail) are a hairstyle of twin ponytails or braids on opposite sides of the head. Bedouin woman with braided pigtails, between 1898 and 1914. Depending on the person's hair length and thickness, pigtails can either be two high ponytails, two low. Dear Straight Dope: Where do they get the term “pigtails” since there aren't two tails or a split? Daniel Kordan Dex replies: The first use of the term pigtail was, of course, to refer to the tail of a pig. By the mid-1600s, however, it had taken on the added meaning of tobacco twisted into a thin. Pigs only have one tail. What is your opinion? That is an interesting question. Any girls want to take this one? 4. Back. That being said, there's no issue if you're an adult and have your hair parted in this manner as well. Most of us don't really question the term, but when you think about it — it's a strange term. In ancient Greece and Rome, pigtails were a common hairstyle among young girls and women.

Why is the OLT deployed below the core switch
The OLT serves as the starting point of a PON, connecting to the core switch via an Ethernet cable. Cisco introduces GPON with the Catalyst GPON platform. Optical Distribution Network (ODN) - The physical fibre and optical. In short: The OLT (Optical Line Terminal) is the central control unit of a Passive Optical Network (PON). It converts data signals, manages bandwidth, and connects hundreds of users over a single optical fiber infrastructure. Typically placed at the central office to provide a fiber optic interface to the user's passive fiber optic. A GPON system consists of the Optical Line Terminal (OLT), Optical Network Unit (ONU), and Optical Distribution Network (ODN). Depending on the access scenario,ONUs can be deployed in corridors. In a PON network, an OLT is deployed at the service provider's central office, and many ONU devices or optical ONT devices and optical splitters (SPLs) are near the end users. In addition, ODNs are used for data transmission between OLTs and ONUs/ONTs.
