Tellabs upgrades backhaul family for LTE-Advanced
Promises flexible migration to 4G with expanded range of interfaces and sync options, and boosted capacity
Published: 24 February, 2012
Tellabs recently pulled back from an ambitious program to get into the packet core in order to concentrate its resources on its main backhaul and router businesses. However, the firm still has its eyes on next generation markets, and it has announced a full refresh of its mobile backhaul range, designed to ease future migration to LTE-Advanced.
Tellabs says that about half of its 160 mobile backhaul customers will move to LTE and/or LTE-Advanced by mid-decade. To try to keep those clients loyal in an increasingly competitive market, the vendor has upgraded its 7100 and 7300 fiber optic products, as well as its 8600, 8800 and 9200 smart mobile backhaul units, all of which will now support the move to 4G without a 'forklift' update. Operators can switch on LTE and LTE-A features incrementally as required, and can mix and match different generations of the 8600 system, including Ethernet and IP-VPN, to support existing and new services.
The renewed 8600 platform can also lower the cost of delivering data by up to 80% in Ethernet deployments, claims the supplier, and deliver speeds of up to 10Gbps to cell sites.
It supports a new Ethernet-based switching and routing architecture, which can deliver the 80% savings on cost per bit with 10G interfaces, and 76% with Gigabit Ethernet. The family still has IP-VPN and multiservice capabilities and the 8800 comes with new IP-VPN enhancements and higher link efficiency.
Michael Howard, principal analyst at Infonetics Research, commented in the Tellabs statement: "In our view, the Tellabs Mobile Backhaul Solution set and roadmap have the suite of timing and sync functions that satisfy the needs of LTE and LTE-A backhaul networks."
Tellabs is also boasting a wide choice of built-in synchronization and syntonization (frequency alignment of network clocks) schemes. The 8600 includes IEEE1588v2 frequency support and compatibility for phase and time of day support; while the 8800 has added synchronous Ethernet. On a full duplex basis, the top end 9200 system can provide up to 5.5Tbits capacity, while the 8630 provides up to 80G, the 8660 provides 240G, and the 8800 up to 360G.
