A Next-Generation Tool for Broadband Deployment
EXFO’s CoLT-350 is the perfect tool for any service provider deploying VDSL2, ADSL2+ and triple-play services. It has been designed to stand up to the challenges of the outside plant environment. The CoLT-350’s small form factor, rugged design and easy-to-use menu system are ideal for installation technicians. It makes the test process highly automated, and allows technicians to close their jobs quickly and efficiently.
The CoLT-350’s large display makes it even more user-friendly, and when it comes to saving results, it provides technicians with many connectivity options for uploading tests and compiling reports.
Test Traditional ADSL and Newly Deployed VDSL2
CoLT-350 is based on the industry-leading Broadcom chipset, which ensures excellent interoperability for VDSL2 and ADSL2+ when testing against other Broadcom-based devices and other vendors’ chipsets. It also allows the use of Broadcom’s ADSL2+ Nitro mode to negotiate with Broadcom-based DSLAMs in order to achieve data rates as high as 30 Mbit/s (depending on DSLAM setup, loop length, noise influences and circuit quality). Nitro™ is a proprietary Broadcom approach that increases the throughput on links by compressing the ADSL2+ ATM header, thus requiring fewer bits to be transmitted.
Ensuring the highest quality triple-play services to customers is a must for service providers, but it is also quite a challenge with aging copper plant. One industry standard method that helps achieve this is the xDSL impulse noise protection (INP) parameter, which is particularly important when deploying IPTV services based on VDSL2 and ADSL2+. For example, INP helps reduce the amount of macro-blocking in an IPTV stream caused by short duration and intermittent impulse noise spikes. The CoLT-350 has a complete implementation of the ITU-T INP standard for values ranging from 0 to 16.
