What is a cross connect

A Direct Line Between Critical Networks

A cross connect is a dedicated physical or logical link between two network endpoints. Inside a data center, it runs from your rack to a carrier, ISP, cloud on-ramp or another customer, so traffic moves directly instead of crossing the public internet.

The result is a shorter, private path you control: more consistent performance, dedicated bandwidth and a smaller attack surface for the traffic that matters most.

Why cross connect

Built for Performance, Security and Control

A dedicated link removes the variables of public routing, so critical traffic behaves the same way every day.

  • Lower network latency

    Fewer hops between endpoints than a route over the public internet.

  • Private connectivity

    Traffic travels on a link reserved for your endpoints.

  • Improved security

    Sensitive data stays off shared public networks.

  • Predictable performance

    No exposure to public internet congestion or peak-hour slowdowns.

  • Dedicated bandwidth

    Capacity from 100 Mbps to 10 Gbps, sized to your traffic.

  • Network control

    Choose Layer 2 or Layer 3, VLANs, addressing and BGP routing.

  • Scalable connectivity

    Add links, endpoints or bandwidth as your network grows.

  • Enterprise ready

    Designed alongside your colocation, rack space and network services.

Choose the right path

Cross Connect vs Public Internet

The public internet is built for reach. A cross connect is built for the links where consistency, privacy and control matter more.

Cross connect guide

Cross Connect Services in Kolkata, Explained

Everything you need to plan a data center cross connect: how it works, how it compares with other options, which cabling to choose and what to prepare before you order.

How a data center cross connect works

Inside a data center, each customer's equipment sits in its own rack. A cross connect is a cable, fibre or copper, that runs from a port on your equipment through the facility's structured patch panels to a port belonging to the other party: a carrier, an internet service provider, a cloud on-ramp or another customer.

Once both ends are patched and tested, the two networks exchange traffic directly over that dedicated link. Because the path stays within private cabling, there is no public routing in between. That is why a cross connect is more consistent, more private and usually lower in latency than reaching the same network over the internet.

Cross connect vs IP transit vs site-to-site VPN

These three terms often come up together, but they solve different problems. In practice they also work together: IP transit from a carrier is frequently handed off to your rack over a cross connect.

PathDirect, inside the facilityPublic internetPublic internet
PerformanceDedicated and consistentDepends on upstream routesVaries with internet conditions
Best forCarriers, ISPs, partners, DR linksReaching the wider internetLow-cost links to remote offices

Fibre or copper: choosing the right medium

Single-mode fibre carries light over longer distances and is the usual choice for carrier hand-offs and links between facilities. Multi-mode fibre suits short, high-bandwidth runs inside the same building. Copper Ethernet is practical for short in-facility links at lower speeds.

The right choice depends on what both ends support. The interface speed, optics and connector type must match on your equipment and on the other party's port. Our network team confirms compatibility during the design stage, before any cable is run.

What to prepare before ordering a cross connect

Having these details ready speeds up design and provisioning:

  • Both endpoints: who you are connecting to, and where their equipment is
  • Interface type and speed on each side, for example 1G or 10G, fibre or copper
  • Optic and connector type, if you already know them
  • Layer 2 or Layer 3 design, plus VLAN, IP addressing and BGP details
  • Any letter of authorization (LOA/CFA) issued by the other party
  • Your target go-live date and any redundancy requirements

Why connect in Kolkata

For businesses in Kolkata, West Bengal and eastern India, interconnecting carriers, ISPs and partners inside a local data center keeps traffic close to the offices and users it serves, and keeps your hardware within reach of your own team.

At HostGraber DC-01 in New Town, cross connects sit alongside colocation in Kolkata, rack space and private networking, so one infrastructure team plans the rack, the link and the routing together.

Frequently asked questions

Cross Connect Questions Answered

Still deciding on a design? Share your endpoints and our network team will advise.

What is a data center cross connect?

A cross connect is a dedicated connection between two network endpoints, such as your servers and a carrier, ISP, cloud platform or another customer, so traffic moves directly instead of over the public internet.

Is a cross connect private?

Yes. A cross connect creates private connectivity between supported endpoints rather than relying on public internet routing.

What is the difference between a cross connect and IP transit?

IP transit is internet access bought from a provider. A cross connect is the private physical link between two parties inside a data center. They often work together: transit from a carrier is commonly delivered to your rack over a cross connect.

Do you support fibre cross connects?

Yes. Single-mode and multi-mode fibre cross connects can be provided according to facility availability and technical requirements. Copper is also available for short in-facility links.

Should I choose single-mode or multi-mode fibre?

Single-mode fibre suits longer runs and carrier hand-offs, while multi-mode fibre suits short, high-bandwidth links inside the facility. The choice must match the interfaces on both ends, and our network team confirms it during design.

What bandwidth can I get on a cross connect?

Options range from 100 Mbps to 10 Gbps, with custom capacity available on request.

Can a cross connect be used for disaster recovery?

Yes. Cross connects can support replication, failover and private connectivity between eligible primary and disaster recovery environments.

Do you support BGP?

BGP connectivity options are available for eligible network deployments and are reviewed during solution design.

Can I connect to a specific carrier or ISP?

Connectivity to a particular provider depends on its availability at the facility. Share the provider name in the request form and our team will confirm the options.

Can I create Layer 2 connectivity?

Yes. Layer 2 connectivity and VLAN-based designs can be evaluated based on your network requirements and endpoint availability.

What determines cross connect pricing?

Pricing depends on connection type, endpoints, fibre or interface requirements, bandwidth, network configuration and any additional infrastructure services.

How do I order a cross connect?

Fill in the cross connect request form with both endpoints, the connection type and the bandwidth you need. Our network team reviews the requirement, designs the link, provisions and tests it, then moves it into production.
