The LC-LC OM4 Fiber Optic Patch Cord Simplex Duplex Multimode LSZH 2.0mm Cable is a factory pre-terminated OM4 multimode fiber optic patch cord engineered to connect optical hardware equipment, devices and fiber links in high-speed cabling systems. Each jumper is assembled and tested in-house to guarantee transmission performance before shipping, delivering a plug-and-play solution that speeds up network configuration and reduces on-site installation time.
This patch cord uses OM4 (A1a) 50/125 multimode fiber with LC connectors on both ends, available in simplex and duplex core configurations. The LSZH sheath provides durable protection with low-smoke, flame-retardant performance, while the 2.0mm cable diameter offers a balance of flexibility and mechanical strength for patching in data centers, telecommunication rooms and enterprise networks supporting 10G to 100G parallel optics.
Key Features
- Low Insertion Loss: Guaranteed insertion loss of less than or equal to 0.3dB, with interchangeability of less than or equal to 0.2dB.
- High Return Loss: PC multimode polishing achieves return loss greater than or equal to 35dB, ensuring clean signal transmission.
- OM4 10G Performance: A1a 50/125 multimode fiber supports 10G Ethernet links up to 550m for reliable high-bandwidth patching.
- Flame-Retardant Sheath: LSZH jacket meets IEC 60332-3C fire rating with low-smoke zero-halogen emission per IEC 61034-2.
- Standard LC Adapters: Precision LC connectors with ceramic ferrule ensure stable, repeatable mating.
- Custom Tailored Service: Length, core quantity and physical structure can be customized to match project requirements.

Applications
This OM4 fiber optic patch cord provides reliable connections between switches, servers, transceivers and optical distribution frames in data centers, telecommunication rooms, enterprise networks and FTTH access points. It is ideal for 10G/40G/100G parallel optics patching and structured cabling interconnect.
The LC-LC configuration uses compact small-form-factor connectors that maximize port density, making it the standard choice for high-density switch and transceiver patching in modern data centers.
Packaging & Quality Assurance
Each patch cord is individually coiled and sealed in a protective polybag with dust caps on every connector, then packed in export-grade corrugated cartons to prevent crushing during transit. Custom labeling, barcoding and test reports are available for large orders.
Quality is assured through full traceability: 100% insertion-loss and return-loss testing on every connector, 3D interferometry geometry inspection and end-face visual examination before shipment. The factory operates a documented quality management system and supplies compliant test certificates with each batch.
