  6. Why WD1008? • CWDM technology is key in building Metropolitan and Regional networks because it reduces the operational cost of fiber infrastructure (rental and/or maintenance of fiber) • Allows scalable and efficient Gigabit Ethernet services • The combination of CWDM and GBIC enables the design of a flexible and highly reliable multi-service network • Offers a cost effective solution to expanding of network • Create an 8 Gigabit LAN 210km long! • (G8LX/70km – Optical Budget 70km – G8LX/70)

  7. Features • 8 bi-directional channels in 1 pair of fiber OR 4 bi-directional channels using 1 fiber • Slots for up to 8 Gigabit Ethernet-compliant GBIC modules • Maximum operating distances of up to 70 km for the GBIC modules • Embedded test link function on each multiplexing port • Expansion slot for the optional management module • Expansion slot for the optional Redundant Power Supply (AC/DC) • Removable fan tray • SC Connectors • Competitive price and high performance • WD1008 can use the entire suite of Allied Telesyn’s GBICs (G8SX, G8LX-10, G8LX-40, G8LX-40, G8LX-70) – mix GBICs anyway you want!

  8. Benefits • Simplifies network design and management by increasing the bandwidth capacity of legacy fiber optic networks. • Multiplexes up to eight 1000Base Gigabit Ethernet-compliant inputs onto a single fiber pair. • Aggregates full duplex traffic from four GBIC inputs onto each fiber strand which allows for redundancy in equipment and physical fiber routes. • Consolidates traffic from multiple fiber pairs onto single fibers which eases congestion and reduces facility management.

  11. Network Topologies and Applications • Topology • Point-to-point GbE traffic transport • Applications • Increase fiber capacity • 8 wavelengths per pair fiber instead of 2 (up to 4 times the capacity), especially when no other fibers are available • LAN distance extension • Extend transport reach • Benefits • Easier fiber management • Only 1 pair to maintain and service versus up to 4 pairs • Lower capital cost • Cost of GBIC lower than fiber • Pay only when new wavelengths are added

  12. Network Topologies and Applications • Topology • Point-to-point transport path • Application • Spanning Tree protection • Allows path protection over the same pair of fibers • Benefits • Easier fiber management • Only 1 pair to maintain and service versus up to 4 pairs • Lower capital cost • Cost of GBIC lower than fiber • Pay only when new wavelengths are added

  13. Network Topologies and Applications • Topology • Loop-type LAN backbone • Application • Trunking • Allows GbE traffic transport over the same pair of fibers • Multiple site management • Allows one site to manage multiple sites • Benefits • Easier fiber management • Only 1 pair or 2 pairs to maintain and service versus up to 4 pairs or 8 pairs • Less fiber clutter • Lower capital cost • Cost of GBIC lower than fiber • Pay only when new wavelengths are added

  17. Optional Management Module (AT-WDM02) • RS232 direct connect using DB9 connector • In-band 10base-T • SNMP support for both in- and out-of band • Communication line interface via RS232 port • Z-modem and TFTP support for downloading firmware • MIB support: Private MIB • Relative Traffic Monitor for each GBIC port • Valid Ethernet Data Indicator for each GBIC port

  18. Connectors, Indicators and Power Supply • Connectors • A SC optical receptacle on each WD optical port • Indicators • Power LED • Link, Receive and Xmit LED Indicators for each GBIC port • Link, Receive and Xmit for each “remote optical port”. • Power Supply • External Power Adapter AC-DC (110VAC; -48VDC) • Redundant Optional Power Supply (AC-110V); hot swappable • Redundant Optional Power Supply (DC -48V); hot swappable • Chassis/Enclosure • Mini-chassis model; 8 GBIC slots; 2 optical receptacle slots

  21. CDWM (Coarse WDM) Less than 16 wavelengths per system Slow traffic growth Much lower cost Components are less stringent Simpler management Smaller footprint Shorter distance reach Less than 100km Networks that would most likely deploy CDWM Enterprise, Access, Metropolitan DWDM (Dense WDM) From 32 to 80 wavelengths per system High traffic growth Higher cost Components are more stringent because of high wavelength capacity More complex management Larger footprint Longer distance reach From 100km to 1000km Networks that would most likely deploy DWDM Metropolitan, Regional, Long-haul CWDM versus DWDM
