Optical Communication System Solution for Integrated Cabling in Government and Enterprise Office Buildings

📅Oct 8, 2015

Brief：Unlike the fiber integrated cabling requirements of commercial office buildings and residential communities, government and enterprise office buildings often require multiple data services. For example, government offices need internal industry networks for upper and lower levels, government office networks, external public portal networks, and surveillance networks. Enterprises typically have their own internal surveillance private networks, industrial control private networks, and internet requirements. Some units also have telephone and surveillance data needs, while others have remote access requirements. Therefore, fiber access for government and enterprise office buildings cannot simply use common PON networks, as PON networks cannot provide strictly physically isolated Ethernet.

Overall Service Diagram

IDM NTD421 is a device that provides 2 physically isolated wire-speed 100M Ethernet ports for offices, and also offers 2 telephone interfaces. It is equivalent to two media converters plus a 2-channel telephone optical terminal, simplifying installation and maintenance with a neat appearance. It does not require changes to the vertical or horizontal systems of traditional integrated cabling.

IDM NTD421 is aggregated to the central office through 8-port or 16-port IDM GP-MPconv devices (placed in the original ODU location).

The central office device is IDM G3CP, configured with 5Guser cards. It has 4 SFP optical ports and can provide 2.5Gbps optical ports. The remote end connects 4 IDM GP-MPconv units, and the IDM G3CP can accommodate 12 5Guser cards.

For environments with high Ethernet bandwidth requirements, the IDM GTD442 device can be used for access, providing 2 groups of physically isolated wire-speed Gigabit Ethernet and 4 telephone lines. For environments with high telephone service demand, the IDM 3500 series can be used for access. IDM GTD 442 and IDM 3500 series devices can be connected to the central office IDM G3CP via 5Guser cards or 2.5Guser cards.

The central office device IDM G3CP can provide multiple telephone aggregation methods, including access to the switch via FXO, or via digital signaling such as NO.7, NO.1, and PRI.
