Feature:
1.1 Core Types:
Single-mode (SMF): Thin core (~9µm), used for long-distance communication (e.g., telecom, data centers).
Multimode (MMF): Thicker core (~50µm or 62.5µm), used for short-distance connections (e.g., LANs, security systems).
1.2 Connector Types:
LC (Lucent Connector) – Small, widely used in high-density setups.
SC (Subscriber Connector) – Push-pull design, common in datacoms.
FC (Ferrule Connector) – Screw-on, used in high-vibration environments.
ST (Straight Tip) – Bayonet-style, common in older networks.
MTP/MPO – Multi-fiber connectors for high-speed links (40G/100G).
1.3 Cable Jacket Types:
PVC – Standard, flexible, indoor use.
LSZH (Low Smoke Zero Halogen) – Fire-resistant, safer for enclosed spaces.
Armored – Reinforced for harsh environments.
1.4 Polish Types (Affects Signal Loss):
PC (Physical Contact) – Basic polish, slight reflection.
UPC (Ultra Physical Contact) – Lower insertion loss, common in telecom.
APC (Angled Physical Contact) – Angled polish, minimizes back reflection (used in FTTH, CATV).
Application:
2.1 Data centers (connecting switches/servers)
2.2 Telecom networks (FTTx, backbone links)
2.3 Enterprise networks (LAN/WAN connections)
2.4 CCTV & security systems
