conference & convention enabling the next generation of networks & services Flexibility of Configuration OADM SLTE  Cost savings reducing the number of transponders  Planning flexibility:  Traffic sharing not fixed at initial system construction Receive side Receive side Transmit side Transmit side BAND DEMUX BAND DEMUX BAND MUX BAND MUX LOFA LOFA LOFA LOFA CHANNEL CHANNEL CHANNEL CHANNEL DEMUX DEMUX MUX MUX TRBC TRBC TRBD TRBD TRBD TRBD TRBC TRBC

conference & convention enabling the next generation of networks & services Flexibility of Capacity 3.36Tb/ s   Modular architecture allows: - Up to 84 x 10Gb/s channels (50 GHz spacing) - Up to 128 x 10Gb/s channels (33 GHz spacing) 1.60Tb/ s - Up to 160 x 10Gb/s channels (25 GHz spacing) - Up to 84 x 40Gb/s channels (50 GHz spacing) 1.28Tb/ s 0.84Tb/ s  With additional flexibility: - Mix 10Gb/s channels with different spacing & format - Mix 10Gb/s and 40Gb/s channels in the same SLTE - 100Gb/s upgradeability

conference & convention enabling the next generation of networks & services Flexibility for the Customer  Single type 10Gb/s transponder for multiple client signals – 9.95Gb/s SDH STM - 64 / SONET OC - 192 UNI interface – 10G WAN or LAN PHY Ethernet interface – ITU-T G.709 NNI 10.7Gb/s interface  Concatenation of lower bit rate in concentrator blade packs – 8 x 1Gb Ethernet LAN concentrator – 4 x 2.5Gb/s SDH UNI or G.709 NNI concentrator  Pluggable optical interfaces for different reaches – XFP at 10Gb/s, SFP at 2.5Gb/s and GbE

conference & convention enabling the next generation of networks & services Reliability  Wider concept than Digital Line Segment availability – Equipment redundancy and 1+N protection schemes  Robustness to environmental conditions – ETS 300 019-1-3 Class 3.2 (-5 ˚ C to +45 ˚ C with RH ≥ 95%)  Resistance to security threats – Open interfaces on SLTE should be protected by an encryption technique eg. Secure Socket Layer (SSL) to enable secure connection to other computer systems – SSL provides: • Privacy • Integrity • Authentication

conference & convention enabling the next generation of networks & services Ease of Use  Safety first – IEC 60950-1 (Ed.2005) Safety of Information Technology Equipment  Installation - Automatic Commissioning Tools – Minimum on-site intervention – SLTE configuration built off-line • Cabling, slot positions, optical power settings, alarm thresholds, alarm profile management – Downloaded remotely on installed SLTE • Verify correct installation (cabling, slot position etc) • Upload specific pack information • Highlight discrepancies

conference & convention enabling the next generation of networks & services Ease of Use  Commissioning - Local or remote “Zero Installation Craft” Terminals (ZIC) - Any PC with web browser without specific SW installation - Connected locally or remotely, only dependant on LAN/IP connectivity 1 1 HTTP URL HTTP URL 1. Log onto ZIC web server using PC web browser to access a set of ZIC Graphical User Operation Tasks/Web Request Operation Tasks/Web Request 2 2 Interface (GUI) pages Web Web Server Server 2. Through ZIC GUI send IP IP operation requests to the SLTE DWM DWM DWM WDM WDM 3. SLTE returns responses to display on web browser 3 3 SLTE Response SLTE Response

conference & convention enabling the next generation of networks & services Ease of Use - Intuitive, drop-down menus

conference & convention enabling the next generation of networks & services Eco-Friendly: An investment for our future  European Union Directives RoHS and WEEE – Design of eco-friendly SLTE and disposal of packaging and parts at end-of-life  Eco-friendly demands: – Equipment size reduction – Power consumption reduction  ECO Declaration (ECMA-370) specifies measurement of ‘eco-friendliness’ – Power Consumption, Noise emission, Hazardous Substances, Packaging, EOL Management Information

conference & convention enabling the next generation of networks & services The Ideal SLTE - Conclusion  Four key attributes  Ideal SLTE as a tool for the submarine network operator - One single, compact, adaptable tool dependable in any environment, ready for any eventuality SLTE SLTE  The “Swiss Army Knife” SLTE
