What is Fiber Optic Connector?
A fiber optic connector is a precision device that terminates the end of an optical fiber, enabling quick and reliable connection and disconnection between fiber links. It aligns two fiber cores precisely to allow light to pass with minimal insertion loss and back reflection. Fiber optic connectors are essential components in telecommunications networks, data centers, FTTH deployments, and test equipment. YRTFIBER manufactures a comprehensive range of high‑performance fiber optic connectors in LC, SC, FC, ST, MPO/MTP, and E2000 styles, with UPC or APC polish options, to meet diverse network requirements.
Fiber Optic Connector Types
LC Connector – Small form‑factor (SFF) connector with a 1.25mm ferrule. Ideal for high‑density patching in data centers and telecom rooms. Available in simplex and duplex configurations.
SC Connector – Standard square connector with a 2.5mm ferrule. Push‑pull latching mechanism for easy insertion and removal. Widely used in FTTH, CATV, and data networks.
FC Connector – Round connector with a 2.5mm ferrule and threaded metal housing for secure, vibration‑resistant connections. Preferred for telecom and test equipment.
ST Connector – Round connector with a 2.5mm ferrule and bayonet locking mechanism. Commonly found in legacy networks and multimode applications.
MPO/MTP Connector – Multi‑fiber connector supporting 8 to 24 fibers in a single interface. Designed for high‑density 40G/100G/400G data center backbones.
E2000 Connector – High‑performance connector with a spring‑loaded shutter for dust and laser safety protection. Ideal for high‑reliability telecom and CATV applications.

Frequently Asked Questions
UPC or APC – which polish should I choose? APC (Angled Physical Contact) offers lower return loss (≥ 60 dB) and is preferred for analog video, PON, and high‑precision applications. UPC (≥ 50 dB) is standard for most digital networks and offers a more cost‑effective solution.
LC, SC, or FC – which connector is right for me? LC is best for high‑density applications; SC is the most common for FTTH and general networking; FC is preferred for telecom and vibration‑sensitive environments. The choice depends on your equipment and installation requirements.
Singlemode or multimode connector? Singlemode connectors (G.652D/G.657A) are for long‑haul, high‑speed transmission; multimode connectors (OM1–OM5) are for short‑reach data center links. The connector type (LC, SC, etc.) is available for both.
What is the difference between simplex and duplex? Simplex connectors are single‑fiber for one‑way transmission; duplex connectors are two fibers (typically side‑by‑side) for bi‑directional communication.
MOQ? From 100 pieces; best pricing from 1,000 pieces.
Warranty? 3‑year on materials and workmanship.
