Until less than 10-15 years ago, TDM based networks (SDH, SONET) have been the kings of WANs. Then these started to migrate to packet based networks (IP/MPLS, Carrier Ethernet) and very soon we reached the point where greenfield WAN networks were totally based on IP, and the only TDM equipment deliveries were for expansions and maintenance only. Naturally, this dramatically affected the systems market and some vendors went out of business while the remaining ones decided to end life of entire product lines. While this happens, TDM networks are still the main transmission/ backbone networks operated by T1 and T2 service providers, which started to experience ever growing problems in maintaining their existing networks, looking desperately for substitutes to failed equipment and eventually cannibalizing segments of networks to salvage other segments. This way or another, the impact on OPEX became fatal.
Another facet of the same problem is Synchronization: TDM systems heavily depend, by nature, on BITS based Grand Masters. Many of the once popular solutions virtually disappeared from the market place. When it comes to high density BITS Grand Masters, it turns even worse.
Fibrolan can assist you in both: full 3R repeaters/ extenders for up to STM64/OC48 and high- density Grand Masters for BITS alone or combined with PTP.
In addition, Fibrolan’s Falcon-STA and uFalcon-ST series devices allows you to migrate your TDM networks over packet networks in a seamless and cost-effective manner
