Multimode Duplex LC UPC To LC UPC OM4 Optic Fiber Patch Cord 3.0mm
Fiber optic patchcords and pigtails are components to link equipments and components in fiber optic network. There are many types according to different types of fiber optic connector including FC SV SC LC E2000n MTRJn MPO etc with single mode(9/125um) and multimode(50/125 or 62.5/125). Cable jacket material can be PVC, LSZH; OFNR, OFNP etc. There are simplex, duplex, multi fibers, Ribbon fan out and bundle fiber.

Features:
1.1 Core Diameter:
Typically 50µm or 62.5µm (much larger than single-mode fiber’s 9µm core).
Allows multiple light modes (light paths) to propagate, leading to modal dispersion over long distances.
1.2 Distance & Bandwidth:
Optimized for short-range communication (up to 550m for 10Gbps, 1km for 1Gbps).
Higher attenuation compared to single-mode fiber, limiting long-distance use.
1.3 Common Standards & Types:
OM1 (62.5/125µm): Orange jacket, supports 1Gbps up to 275m.
OM2 (50/125µm): Orange jacket, improved bandwidth over OM1.
OM3 (50/125µm, laser-optimized): Aqua jacket, supports 10Gbps up to 300m.
OM4 (50/125µm, enhanced): Aqua jacket, supports 10Gbps up to 550m and 40/100Gbps.
OM5 (50/125µm, wideband): Lime green jacket, supports wavelength division multiplexing (WDM).
1.4 Connector Types:
LC, SC, ST, FC, MTP/MPO (for high-density connections).
Polished finishes (UPC or APC) for low insertion loss.
Application:
2.1 Data centers (server-to-switch connections).
2.2 Local Area Networks (LANs).
2.3 CCTV and video surveillance.
2.4 Medical imaging and industrial systems.
