1 To 4 Core FTTH Cable With Messenger For Outdoor Distribution
Description
The FTTH cable, connecting homes directly, doesn't impose restrictions on bandwidth, wavelength, or
transmission technology. The optical fiber unit is centrally positioned within the cable structure. Two
parallel strength members flank the sides, while an additional steel wire serves as supplementary stre-
ngth. The cable is finalized with a black HDPE sheath for protection.
Application
1 Outdoor and vertical distribution purposes.
2 Seamless connection with communication equipment.
3 Facilitating long-distance and local area network communication.
Characteristics
1 Strong mechanical and environmental attributes.
2 UV resistance meeting pertinent standards.
3 Compliance with mechanical standards.
4 Flexibility, ease of laying and splicing, enabling high-capacity data transmission.
5 Meets diverse market and client requirements.
