Feature:
1.1 Connector Types:
LC-LC Duplex (most common for high-density applications).
SC-SC Duplex (older, bulkier, but still used).
ST-ST Duplex (common in older multimode networks).
Hybrid Duplex (e.g., LC-SC, LC-ST for cross-connections).
1.2 Fiber Types:
Single-mode (OS1/OS2): Long-distance (up to 100+ km), low loss, used in telecom/cable TV.
Multimode (OM1/OM2/OM3/OM4/OM5): Short-distance (up to 550m for 10G), used in data centers/LANs.
1.3 Cable Structure:
Two separate fibers (Tx & Rx) in a single jacket.
Often zip-cord style (can be easily split).
Available in simplex (single fiber) or duplex (dual fiber).
1.4 Polish Types:
UPC (Ultra Physical Contact) – Blue connectors, standard for most applications.
APC (Angled Physical Contact) – Green connectors, used where low back reflection is needed.
1.5 Common Lengths:
Typically 0.5m to 50m, but custom lengths are available.
Application:
2.1 Telecommunication Network
2.2 Fiber Broad Band Network
2.3 CATV system
2.4 LAN and WAN system
2.5 FTTP
