"A 5Mbps leased line costs thousands of HKD per month, but my home 1000Mbps broadband is only a few hundred — why the huge difference?" This is probably one of the most frequently asked questions from enterprise clients. This article breaks down the complete cost structure of IPLC/IEPL leased lines, explains why the pricing is justified, and helps you determine whether you need a leased line.
Cost Structure of a Leased Line
The monthly fee for an international leased line isn't an arbitrary number — it reflects a series of real infrastructure and operational costs. Here's a typical cost breakdown:
Fiber Lease (~35%)
The core resource of an international leased line is fiber optic capacity. Whether submarine or land cables, capacity is limited. Carriers lease specific wavelengths or timeslots from cable owners (China Telecom, NTT, PCCW, etc.). Submarine cable construction costs can exceed hundreds of millions of dollars, and these investments are recovered through bandwidth rentals. A single 10G wavelength on a trans-Pacific submarine cable can cost over US$1 million per year in lease fees. Even for short-distance routes like Guangdong-Hong Kong, fiber access fees make up the lion's share of costs.
Landing Station and Data Center Fees (~20%)
Where submarine cables come ashore is called a "Cable Landing Station." Each leased line requires optical signal amplification, conversion, and cross-connection at landing stations on both ends. Landing stations are high-security facilities with expensive operations and maintenance. Additionally, the "last mile" fiber connection from the landing station to the customer's data center incurs extra costs — in Tokyo or Hong Kong data centers, a single cross-connect can cost several hundred to over a thousand HKD per month.
Network Equipment (~15%)
Professional transmission equipment must be deployed at both ends: optical transport platforms (OTN/DWDM), Ethernet switches or SDH equipment, optical modules, etc. These carrier-grade devices cost far more than consumer routers — a single 100G optical module can cost over HK$100,000. Equipment requires periodic replacement and upgrades, and these costs are amortized into the monthly fee.
Maintenance and Monitoring (~15%)
Leased lines require 24/7 monitoring. The carrier's NOC (Network Operations Center) monitors performance metrics for every circuit around the clock — latency, packet loss, optical power levels, etc. When faults occur, engineers must locate and resolve the issue within SLA-defined timeframes (typically under 4 hours). This requires deploying technical teams across multiple cities and coordinating with submarine cable maintenance vessels and landing station operators. Labor costs are the primary component here.
SLA Guarantee (~15%)
Leased line SLAs (Service Level Agreements) typically promise 99.9%+ availability. To deliver on this commitment, carriers must build redundant routes — when the primary route fails, traffic automatically switches to a backup route. This means each leased line actually maintains at least two physical paths' worth of resources behind the scenes, while customers only pay for one. The cost of protection routes is distributed across all customers' monthly fees.
Comparison with VPN/Tunnel Solutions
There are many cross-border VPN or tunnel solutions available for $50-200/month. How do they differ from leased lines?
The essence of VPN/tunnel solutions is an encrypted tunnel over the public internet. The underlying transport is still shared public bandwidth — your data travels on the same fiber and through the same routers as tens of thousands of other users. This means:
- No bandwidth guarantee: Advertised as 50Mbps but may drop to 5Mbps during peak hours
- No latency guarantee: 80ms normally, 300ms during congestion
- No SLA: When it goes down, it goes down — no compensation, no committed restoration time
- No compliance: Some tunnel solutions operate in legal gray areas, unsuitable for legitimate enterprises
The essence of a leased line is dedicated physical resources. What you're paying for is: a dedicated segment of fiber capacity + equipment and interfaces on both ends + 24/7 monitoring + SLA commitments + a compliant telecommunications service. It's like the difference between a private driveway and a public highway — of course the private driveway costs more, but it will never have traffic jams.
5Mbps Dedicated ≠ 5Mbps Shared
This comparison is critically important. The "1000Mbps" advertised on home broadband is shared bandwidth — all users in your building or neighborhood share a single uplink. During peak evening hours, your actual usable bandwidth may be only 10-20% of the advertised speed.
A leased line's 5Mbps is dedicated bandwidth. Anytime, anywhere, you can always utilize the full 5Mbps with consistent latency and packet loss. Think of it this way:
- Home broadband = a lane on a public highway. Smooth sailing when traffic is light, gridlocked during holidays.
- Leased line = a private tunnel from your location to the destination. Only your vehicles use it — never congested, always the same speed.
For workloads requiring stable latency (financial trading, real-time video conferencing, game server synchronization), 5Mbps of dedicated bandwidth is far more valuable than 100Mbps of shared bandwidth.
Areapac's Pricing Strategy
We understand SME budget constraints. Areapac's leased line products start at HK$500/month (Shanghai-Tokyo route), including:
- Dual-end VMs (virtual machines) — no need to provide your own servers
- Dedicated bandwidth with guaranteed latency and packet loss rates
- Dedicated IP address
- 24/7 technical support
- 99.9% availability SLA
We achieve this price point by purchasing fiber capacity in bulk directly from Tier-1 carriers and reducing labor costs through automated operations. We don't add margins in the middle — we pass the savings on to our customers.
For enterprise customers needing larger bandwidth or more routes, we offer tiered pricing — the more bandwidth you use, the lower the unit cost. Contact our sales team for a customized quote.
The Value Equation: Downtime Cost vs. Line Cost
When evaluating whether a leased line is "worth it," the right question isn't "how much does it cost per month" but "how much could I lose without one."
Cross-border e-commerce: An e-commerce platform with daily GMV (Gross Merchandise Value) of RMB 1 million — if network instability causes payment page timeouts and conversion rates drop by 5%, daily losses are RMB 50,000. Monthly losses could exceed RMB 1.5 million, while a leased line costs just a few thousand per month.
Live streaming: A live broadcast event with 100,000 viewers — if push-stream network jitter causes 30 seconds of stuttering, viewer dropout rates could reach 20%. For a live commerce stream, revenue might be several thousand yuan per second — the direct and indirect losses from 30 seconds of stuttering far exceed an entire year of leased line fees.
Financial trading: In high-frequency trading, every 1ms of latency advantage can translate to millions of dollars in annual revenue difference. In this scenario, the cost of a leased line is virtually negligible.
Ultimately, a leased line isn't a cost — it's insurance and an accelerator.
One-Line Summary
IPLC/IEPL leased lines cost what they do because you're paying for dedicated physical resources, round-the-clock operational support, and legally binding SLA commitments. For businesses that depend on cross-border networking, the ROI on a leased line is almost always positive.
