The Ideal SLTE – 4 key attributes

Reliability Flexibility Reliability Eco-friendly Ease of Use

conference & convention

Flexibility: A blade for any purpose Flexibility of Configuration

• Transoceanic, regional or unrepeatered systems
• Line Terminal, OADM, Dry Repeater
• Line Terminal, OADM, Dry Repeater

Flexibility of Capacity

• Channel spacing, bit rate

Flexibility for the Customer

• Intrinsic traffic flexibility
• Selectable plug and play modules

Flexibility of Capacity

Modular architecture allows:

• Up to 84 x 10Gb/s channels (50 GHz spacing)
• Up to 128 x 10Gb/s channels (33 GHz spacing)

• Up to 160 x 10Gb/s channels (25 GHz spacing)

.*.+&-

• Up to 84 x 40Gb/s channels (50 GHz spacing)

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

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

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%) – 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 connection to

• ther computer systems

– SSL provides:

• Privacy
• Integrity
• Authentication

conference & convention

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 – 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

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

Ease of Use

connectivity 1. Log onto ZIC web server using PC web browser to access a set of ZIC Graphical User Interface (GUI) pages 2. Through ZIC GUI send

• peration requests to the SLTE

3. SLTE returns responses to display on web browser

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: 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
