Title: New Gigabit Ethernet solution from Transmode doubles traffic capacity and lowers operational cost - Highly cost effective IP backhaul networks enabled by new Double Dual GbE Transponder

Transmode today introduced a new plug-in unit for its TM-Series (formerly Mentis) platform, the Double Dual Gigabit Ethernet Transponder. This Small Form-factor Pluggable based card allows the deployment of small-footprint, fully-integrated low-cost Metro WDM nodes enabling highly economical backhaul of Gigabit Ethernet traffic generated by DSL and Cable-based broadband access systems. The card supports four Gigabit Ethernet signals electrically multiplexed into two wavelengths, with optional 1+1 protection on each wavelength.

The Double Dual GbE Transponder can be installed in any TM-Series chassis, including the 1 RU (Rack Unit) TM-101 subrack, creating a compact fully integrated WDM node with add/drop optical filters, multiple GigE client signals, protection and in band management capabilities. With a selling price of well under $10,000, this solution is optimized to address the fast growing IP-traffic backhaul market.

"The card is ideally suited for "Triple-play" applications, where operators need high bandwidth to transfer TV, telephony and Internet services over an IP network, at very low cost. The response from our customers regarding this unit is very positive and we expect it to become a high volume product within our portfolio", said Magnus Öberg, Transmode's Chief Technology Officer.

The Double Dual GbE Transponder supports multiple built in functions, each controlled by software developed by Transmode:

	Up to 4x GbE on two wavelengths, in either point-to-point or ring configurations.
	Built-in line protection, increasing the network capacity to two working and two protection wavelengths, providing a low cost and highly reliable solution for traffic links with high demands of availability.
	In-band management channel, removing the need for external network management connections.
	Built-in repeater function, allowing cascaded nodes to extend system reach to multiple spans, with each span up to 100 km.
	Expansive Performance Monitoring and GbE utilization monitoring, allowing operators the opportunity to monitor and bill on a capacity usage level.

By providing this extensive functionality with the flexibility and operational expenditure (OPEX) advantages of Small Form-factor Pluggable (SFP) optics in a compact transponder unit, Transmode is providing network operators with unprecedented network design options. This unit is already proving very popular with Transmode's existing customer base and has been a key factor in some of Transmode's recent customer wins, including Telenor, the Tier 1 Norwegian PTT and Global Service Provider.
