Upgrading Metro-E Network with CWDM Solution
Project Background
A Singapore-based multi-location enterprise was facing rising operational costs due to premium Metro-E subscriptions across multiple sites.
The ISP charged incremental pricing based on:
- Bandwidth tiers (low to high capacity)
- Single vs. multiple network services
As bandwidth demand increased and new networks were added to support business growth, operational expenses escalated significantly.
The Challenge
The enterprise needed a more cost-effective and scalable alternative while maintaining enterprise-grade security.
Key requirements included:
- Reduce high Metro-E recurring costs between two major sites
- Support future bandwidth growth and additional networks
- Ensure minimum FIPS-140-2 compliant encryption for sensitive data transmission
- Maintain high performance without latency or throughput degradation
Starview’s Solution
Starview Technologies, as the authorized reseller of PacketLight, designed a private CWDM network architecture leveraging leased dark fiber for secure point-to-point connectivity.
The recommended solution: PacketLight PL-1000TE
Key Deployment Elements:
- Leased Dark Fiber from ISP for fully private connectivity
- CWDM-based optical transport between two major sites
- PL-1000TE supporting up to 8 multi-rate transponders
- Configurable speeds from 622Mbps up to 40Gbps
- Flexible mix of multi-rate, multi-protocol services
- Integrated Layer-1 optical encryption for:
- 1G / 10G / 40G Ethernet
- 4G / 8G / 16G Fibre Channel storage
The PL-1000TE is an advanced, all-in-one CWDM/DWDM transport solution ideal for connecting data centers or disaster recovery sites. It integrates a rich feature set with low power consumption while maintaining operational simplicity.
PL-1000TE – Multi-Rate Transponder & Layer-1 Encryption
The solution enables:
- Multi-service aggregation over a single fiber pair
- Dedicated wavelength allocation
- End-to-end encrypted optical transport
- True Layer-1 encryption with no impact on network performance
