Metro Capacity - Metro Fiber
Open Peering offers Metro (Dark) Fiber between almost all neutral datacenters in and around Amsterdam.
Dark Fibers can by lid by endusers at gigabit or ten gigabit speed very easily, directly from their switch or router equipment, and can be used for all types of traffic including standard ethernet, dot1.q VLAN ethernet trunks, MPLS and SDH. Dark Fibers can also be split into multiple wavelengths (colors) using CWDM or DWDM technology, in order to combine multiple gigabit and/or ten gigiabit connections over one link.
Dark fibers are a passive and transparant (no active carrier switch equipment inbetween) form of Metro Capacity and therefor do not depend on availability and funcionality of carrier equipment, like for example Metro Ethernet does. Further Dark Fiber can be used for ten gigabit ethernet connections, and to create your own CWDM and DWDM wavelengths, which is not possible with the Metro Wavelength product.
Lid by customer
The Metro Fibers provided by Open Peering are dark, which means that the customer uses lasers in it's own switch or router equipment which light up the fiber to make actual network connections.
After an order has been placed, Open Peering specifies the expected (theoretical) minimum power budget (expressed in dB) the customer lasers will have to confirm to (largely based on the distance between two connected datacenters in kilometers). After order delivery Open Peering will be able to specify the exact required power budget (based on actual OTDR attenuation/loss measurement on that fiber).
The Open Peering Metro Fiber service is a passive service which means that no active network equipment (e.g. routers, switches, or anything that uses electrical power) is used by Open Peering to provide the service. The lack if active equipment reduces the chance on failures, outages or performance issues, and guarantees the absence of any software limitations.
Customers can use the Metro Wavelengts of Open peering for all types of services included standard ethernet, dot1.q VLAN trunks, MPLS, SDH, etc.
1 or 10 Gigabit capacity
Open Peering Metro Fibers are commonly used for both 1 and 10 Gbit/s ethernet connections.
The Open Peering Metro Fiber service is implemented as a physical fiber that runs via a route through well protected underground tubes between two datacenters. If however the tube and fiber are physically damaged, for example by a digging excavator, the Metro Fiber service is impacted and, different then with Metro Ethernet, NOT automatically rerouted via a different physical fiber route.
Outages and repair
For restoration of the service after an outage, the physical fiber needs to be repaired. Repair can take upto 4 to 8 hours, If there is damage on the tube or fiber, but the Metro Fiber service was not impacted, still emergency maintenance might be required to repair the tube and fiber and prevent future outages. The chance on an unplanned outage or emergency maintenance is very small: on average less then once per 5 years.
During planned maintenance on the physical fiber or tube, for example due to government ordered diversions, the Metro Fiber service will be down and not automatically be rerouted over other paths. Such diversions don't happen often (on average less then 1 time per year), are always announced well in advance and are executed only during a nightly maintenance window. Outages due to planned maintenance are generally limited to 1 hour or less.
In order to improve availability and redundancy it is possible to order two seperate Open Peering Metro Fibers which follow different and non-overlapping physical metro routes. As it is very improbable that two fiber routes are damaged or under maintenance at the same, this stongly reduces the chance on planned or unplanned outages. Further a second Metro Fiber of course doubles the available capacity. A second Metro Fiber via a different (redundant) path generally is longer and more expensive.
Does not include patchcable
The demarcation point of the Metro Fiber service is the port on the Open Peering patchpanel in each datacenter. After an order is placed with Open Peering, in the order confirmation patchpanel port ID's will be assigned. With those port ID's the customer can order patchcables from its equipment to the Open Peering patchpanel port with the datacenter directly.
Lighting the fiber with lasers
The fiber provided by Open Peering is 'dark'. The wavelength provided by Open Peering is 'dark'. The customer will need to light up the fiber using lasers (SFP or GBIC) in his equipment (compatible with the 1000BASE-X standard as specified in IEEE 802.3z) with enough power budget (in dB or decibel). The required minimum laser power budget for a link on short distances (1310 nm, possible upto 10 km), a On-Net distances (1550 nm upto 40 km) and long distances (1550 nm upto 110 km) will be communicated by Open Peering in the order conformation.
Delivery time of all products is max 6 calendar weeks, but generally we can do it (much) faster. Please reserve some time after this order delivery to jointly thoroughly check on both sides if the connection is 100% okay before taking it into production.
