“EIT Deploys Huawei DWDM network for Execulink Telecom”

For immediate release

BROCKVILLE, ONTARIO, June 28, 2012 - A few years ago, who would have thought an

optical network running OC-48 (2.5Gig) would reach capacity within an Independent

Operating Carrier’s (IOC’s) network? That’s just what happened with Execulink Telecom’s

(Execulink) network. As a major communications service provider based in South Western

Ontario, Execulink’s business has seen a steady growth, not only in an increased customer

base but also in the demand for more bandwidth. Supporting both residential and business

customers, Execulink continues to offer services that are meeting customer needs for today

and tomorrow.

Ever increasing requirements for more Internet and fast growing high demand applications

such as IPTV, Execulink quickly outgrew their OC48 SONET network. The immediate need

to grow is critical for Execulink to meet the current demands and the ability to expand as the

need arises.

Being fibre strand constrained meant that Execulink’s options were limited. Knowing

of EIT’s background in Transport and their relationship with Huawei (Canada),

Execulink contacted EIT in search of an equitable solution for their network issues. A

team effort by EIT and Huawei resulted in the design of a robust 250km, 8-site DWDM

network with a starting capacity of 8-10Gig wavelengths.

This gave Execulink the ability to add and drop 10Gig circuits at numerous points along the

path to bridge on additional traffic and to pick up additional services along the way. Through

efficient network design and optimization by EIT, Execulink was able to reuse wavelengths

along the path so only three wavelengths of the initial eight will be utilized in day one. This

gave Execulink 5 more 10Gig wavelengths for growth with no additional expense on adding

extra DWDM hardware, Optical Amps or Dispersion Compensators.

In fact, the system can grow to support 40 10Gig wavelengths with only the addition of

Optical Add/Drop Muxes and client cards.

In a single night Execulink’s existing traffic was migrated from the current SONET

equipment onto the DWDM system. As part of the service, EIT was also instrumental in the

success of the turn-up by providing Network Design Engineering, Installation Site

Engineering, System Line up, Testing and Cutover Support to compliment the DWDM

product.

Around Huawei’s OSN1800 CWDM/DWDM platform, the OSN1800 comes in a 4-slot 1RU

and 8-slot 2RU chassis that can be stacked at a site as one logical Network Element. A

variety of client cards can be added supporting FE, GE, 10GE, OC3/12/48/192 and even

T1’s. As an example, the T1 cards will mux the sites T1’s onto an OC3 and through the

client card it will mux additional OC3’s onto a single wavelength for a more efficient use of

the wavelength.

The T1/OC3 card makes the OSN1800 a great replacement for the existing SONET

Optical Network Elements (NE’s) still in place today. Systems like the Alcatel 1603,

Nortel Optera 3400 and 3500’s are nearing end of life. The Huawei OSN1800 provides

a cost effective solution when it comes to migrating traffic from old legacy equipment

and the ability to expand the capacity on existing fibres for years to come.

applications you may be interested in.
