Cable Cross -Section
Fiber: G.G652D, G.657A1, G.657A2
Feature:
- Smaller diameter
- Frees up capital to expand network and client base
- Network design flexibility
- 5/3.5mm microduct suitable
- Easy to upgrade
- Greater blowing distance
- Fiber: G.G652D, G.657A1, G.657A2
Standards:
- Unless otherwise specified in this specification, all requirements shall be mainly in accordance with the following standard specifications.
- Optical fiber:ITU-T G.651、G.652、G.655、G.657 IEC 60793-2-10、IEC 60793-2-50
- Optical Cable:IEC 60794-1-2、IEC 60794-5
- Note: It is recommended that the structure of 2 fibers unit consist of 2 filled fibers, for it is proved that this structure is better in the blowing performance and the fiber separability than that of one with zero or one filled fiber
