Yuehai Water Supply Park Network Project

Project Background

Yuehai Water Supply is primarily engaged in the supply and sale of untreated natural water to cities such as Shenzhen and Dongguan, as well as the maintenance and construction of water supply projects. The customer currently has an office park with multiple buildings separated by a lake, requiring interconnection of various services between them.

Business Challenges

1. Between the two buildings on opposite sides of the lake, only one spare fiber core is available. The network needs to carry multiple different services: internal data network, video surveillance, broadcast voice, etc.

2. No rack space is available; equipment must be placed in hallway optical distribution boxes.

3. The equipment must operate stably with zero maintenance.

Fholink Solution

1. Adopt Fholink's FH-CWDM passive plug-in WDM solution, designed to fit easily into optical distribution boxes.

2. Use coarse wavelength division multiplexing technology with 20 nm channel spacing. Adjacent channel isolation ≥ 40 dB, crosstalk nearly 0.

3. Deploy a single-fiber bidirectional transmission system, enabling multiple different optical signals to be transmitted simultaneously over a single fiber core.

Customer Benefits

1. Achieve transmission of multiple services (internal data, voice, video, alarms) using only one fiber core.

2. Plug-in passive WDM is compact, low-cost, and operates stably.

3. The equipment requires no power supply and is plug‑and‑play, saving installation and commissioning time.

4. After deployment, the equipment runs stably with no maintenance, reducing operational costs.
