Data Center Connectivity Costs: A Breakdown of Cross-Connects, Bandwidth, and Carrier Fees

SpendWire Team•3 min read•November 11, 2026

Data center telecom costs are opaque and often inflated. Here is what you should actually pay for connectivity.

Data center connectivity is one of the most opaque cost categories in enterprise telecom. Between colocation providers, carriers, cross-connect fees, and bandwidth charges, the cost structure is complex and highly negotiable — if you know what to challenge.

Cost Components

Cross-Connect Fees

A cross-connect is the physical cable linking your equipment cage to a carrier's equipment in the same data center.

Copper cross-connect: $50-200 per month

Single-mode fiber cross-connect: $100-300 per month

Multi-mode fiber cross-connect: $100-250 per month

Installation: $250-500 one-time

These fees are charged by the colocation provider, not the carrier. For enterprises with 20-50 cross-connects, this is $2,000-15,000 per month in cable rental fees alone.

Carrier Port Charges

Once the cross-connect reaches the carrier's equipment, you pay for the port:

1 Gbps Ethernet port: $200-500 per month

10 Gbps Ethernet port: $500-2,000 per month

100 Gbps Ethernet port: $2,000-8,000 per month

Bandwidth/Transport Charges

The actual bandwidth delivered over the port:

Dedicated Internet Access (DIA): $1-5 per Mbps per month at scale

MPLS/private WAN: $3-15 per Mbps per month

Cloud on-ramp (AWS Direct Connect, Azure ExpressRoute): $0.02-0.05 per GB plus port fees

Power and Space

While not strictly telecom, these data center charges directly correlate with connectivity equipment:

Cabinet/cage rental: $500-2,000 per month per cabinet

Power: $100-300 per kW per month

Environmental monitoring: $50-100 per cabinet per month

Where Costs Inflate

Unnecessary Cross-Connects

Enterprises accumulate cross-connects over time and rarely disconnect old ones. A circuit was decommissioned 2 years ago, but the cross-connect to the carrier's cage still bills monthly. Audit your cross-connect inventory against active circuits.

Port Speed vs Actual Usage

Paying for a 10 Gbps port while pushing 1.5 Gbps of traffic wastes $300-1,500 per month. Measure actual throughput and right-size port speeds at contract renewal.

Carrier Diversity Premiums

Using two carriers for redundancy is standard practice. But some enterprises have 4-5 carriers in each data center, each with their own cross-connects, ports, and contracts. Consolidating to 2 carriers with proper diversity achieves the same resilience at lower cost.

Stale Contracts

Data center connectivity pricing has dropped 10-15% per year for the last decade. A contract signed 3 years ago is 30-45% above current market pricing. Renegotiate or re-compete at every renewal.

Optimization Strategies

Audit cross-connects annually and disconnect unused ones

Right-size port speeds based on actual throughput data

Negotiate cross-connect fees with your colocation provider (they are highly negotiable)

Consider cloud exchange providers like Equinix Fabric or Megaport for more efficient multi-cloud connectivity

Benchmark Numbers

For a typical enterprise data center deployment with 2 carriers, 10 Gbps connectivity, and 20 cross-connects, expect $8,000-15,000 per month in total connectivity costs. If you are paying more than $20,000 per month for a similar setup, you have significant optimization opportunities.
