As we all know, in order to ensure the quality of optical cables and ensure that the optical cables can transmit communication models normally after installation, single reel inspection and reel matching must be carried out before the optical cables are laid, and strict.

OCC's Modular Advanced Reel System (MARS ®), the industry's first lightweight cable deployment reel system, is designed specifically for the demanding needs of harsh-environment fiber optic installations. The rotary joints are protected inside the drum for durability and seamless deployment of single or multi-channel fiber optic and/or electrical cable with uninterrupted optical and/or electrical signal. As the components like fiber, connectors, splices, LED or laser sources, detectors and receivers are being developed, testing confirms their performance specifications and helps. Fiber optic cables can be custom cut by Proterial Cable America or distributor to match your required lengths for each cable run. Alternatively, you can order a reel matching the total length needed and cut your own segments as necessary. We advise you to incorporate a safety buffer when ordering. The reel's structural components consist of two flanges, central drum, flange bolts, SmartReelTM test connector and horizontal wood slats (Figure 1) that keep the reel in alignment and protect the fiber cable from any damage that may occur during transporting and storage.
