Highlights

  • Supported transmitting 18 wavelength signals on the same fiber, significantly improved bandwidth utilization.

  • Reduced costs with CWDM equipment for medium-to-short distance transmission, and lowered overall network construction and maintenance expenses.

  • Enabled flexible wavelength additions based on demand with network expansion and upgrades with monitor port.

Key Stats

  • Point-to-point network over 3.4km between two sites.

  • The CWDM solution saved US$880.

  • The lead time of CWDM modules was reduced by 15 days.

  • A 3dB power budget was reserved to ensure reliable transmission as fiber aging increases loss over time.

Overview

Tier.Net is a creative web hosting company providing unparalleled services. It focuses on helping our clients to build a successful business on the web. The company provides shared, reseller, VPS, cloud, dedicated, and co-location services. US-owned with offices in New York and Florida, Tier.Net operates in data centers strategically located throughout the USA and beyond. The data centers are located in Charlotte, NC, Roseburg, OR, Dallas, TX, Los Angeles, CA, Monticello, IA, and Las Vegas, NV. All premium tier 3 data centers serve customers around the world with multi-homed bandwidth and N+2 redundancy. Tier.Net’s data center locations provide outstanding connections to the United States, Asia/Pacific, and Europe. Tier.Net chose FS, hoping FS can help them establish a 3.4km transmission network between the two sites.

Challenges

Tier.Net had not previously purchased MUX/DEMUX products and was unfamiliar with their features or pairing. Meanwhile, Tier.Net used G.652D fiber but could not provide fiber loss data at the @1550nm and @1310nm wavelengths. This caused certain difficulties in formulating the solution.

Tier.Net had a limited budget for this two-site optical transmission project. They were most concerned about product prices and sought a cost-effective yet efficient optical transmission solution that could meet their requirements.

Apart from that, Tier.Net was highly concerned about the product delivery time, as the project was urgent. They needed to receive the CWDM modules as soon as possible.

Solutions

FS team explained the features and pairing of the MUX/DEMUX products and helped Tier.Net make a better choice for the products. Since Tier.Net could not provide the link loss values, the FS technical team reserved a 3dB power budget during the solution design to ensure the system could maintain normal transmission as fiber aging increased loss. This helped avoid excessive receiver power or input power that was too low to affect signal reception. Meanwhile, the CWDM-SFP10G-20 power budget of 15-18dB in the solution met the overall link loss requirements without the need for dispersion compensation.

Due to Tier.Nets's limited budget and concern about cost, the FS technical team specifically designed a cost-effective CWDM solution for them, saving $880.

The initial delivery time for the CWDM module was mid-August. However, due to Tier.Net's strong focus on delivery time, FS accelerated the process and completed delivery half a month ahead of schedule.

Results

FS CWDM solution optimizes bandwidth by integrating up to 18 wavelengths on a single fiber using Mux/Demux technology. Ideal for medium-to-short distances, the CWDM solution reduces network construction and maintenance costs, saving Tier.Net $880. The solution is easy to deploy, conserves fiber resources, and supports flexible wavelength expansion, ensuring compatibility with existing networks and protocols. Reduced CWDM modules lead time by 15 days accelerated project implementation, offering an efficient, cost-effective, and scalable optical transmission network.
