LightExplorer LX3800 - Multi-protocol CWDM MUX

The LightExplorer LX3800 is a powerful multi-rate CWDM transport device with 8 channels, ideal for protocol-independent applications. Offering 70+ km transport in a 1RU chassis design, it features redundant power supplies, standard SFP tributary interfaces, and integrated management options. The LightExplorer series, including the AT-LX3811 line-card based module, enables service aggregation for data, voice, and video, extending connectivity up to 70 km while minimizing CAPEX through modular architecture. Ideal for fiber relief and managed fiber services, this transport solution ensures scalability and compatibility with other Allied Telesyn products.

  1. Light Explorer - LX3800 Multi-protocol CWDM MUX

  2. Multi-rate CWDM Transport 8 Channels Protocol Independent Rate Adaptive (100Mbps – 2.7Gbps) Input 20 Gbps Transport: 70+ km Uni-directional line ports 1RU Chassis Design 8 slot chassis, line-card based AT-LX3811 Redundant, load sharing Power Supplies (AC or DC) Standard SFP tributary interfaces Integrated Management 10/100 Ethernet or RS-232 Interface SNMP, Telnet, or console management options Alarm reports and event log Diagnostic capabilities: Line-card, chassis, & power supplies LightExplorer

  3. Optical Transport Family LightExplorer Series AT-WD1004 • 70+km reach • SNMP Management • Redundant Power (option) • SFP Fiber Interfaces PASSIVE ACTIVE WaveGlider Series FIXED PROTOCOL MULTI-RATE/MULTI-PROTOCOL

  4. LightExplorer • Service Aggregation • Data • Voice • Video • Fiber Relief • Managed Fiber Services • LAN/SAN Extension

  5. LX3800 - Scaleability • Modular architecture ensures that CAPEX is minimised by only installing the minimum number of active line cards. AT-LX3811 ‘Line Card’ SFP Module

  6. LightExplorer T1/E1 over Fiber SONET SDH ATM Fiber Channel Fast Ethernet Gigabit Ethernet ESCON T1/E1 over Fiber SONET SDH ATM Fiber Channel Fast Ethernet Gigabit Ethernet ESCON • Interconnect multiple services with a single device • Extend connectivity up to 70 km in native format • Leverage existing infrastructure • “Pay as you grow” via slotted architecture

  7. LightExplorer • Two-fiber transport for up to 8 services • 8 wavelengths transmit on one fiber • 8 wavelengths received on one fiber • Differs from AT-WD1008: uses bi-directional line fibers • Allows interoperability with Allied Telesyn WaveGlider • Individual channels can be added or dropped as needed • Removes the need for an active book-end solution • Combined with CWDM GBIC/SFP modules, WaveGlider can demultiplex LightExplorer wavelengths • A growth path to point-to-point transport protection • Future line-side protection will interoperate with AT-LX3800U

  8. LightExplorer + WaveGlider Site A RemoteSite 1 L2/3 Switch GbE RemoteSite 2 SAN FC RemoteSite 3 E1 overFiber • AT-2300 Add/Drop Multiplexer • Single channel add/drop at remote sites • Protocol independent OADMs • Eliminates the need to terminate all services at a single add/drop location • High-isolation of dropped wavelengths enhances security, allows wavelength re-use Site B

  9. LightExplorer + WaveGlider 2x GbE 1x Fiber Channel 1x T1 over Fiber Site A 4x GbE 2x Fiber Channel 2x E1 over Fiber 2x GbE 1x Fiber Channel 1x T1 over Fiber • AT-3300/4300 CWDM Multiplexers • Fixed, secure connections over one pair of fiber • Each service stays secure through CWDM multiplexers • Single LightExplorer at central office supports multiple remote sites • WaveGliders at far end keep active equipment in central office

  10. LightExplorer Chassis 1 RU tall/19-inch rack mountable • Management LEDS • SNMP and Telnet management Optional second power supply • AC or DC, load sharing when both units installed • Hot-swappable with integrated fans AT-3801 Blank Line Card • Protects unused slots, keeps contaminants from the internal fiber connections • Chassis ships with AT-3801s in all 8 slots

  11. LightExplorer Line Cards AT-LX3811/x Multi-rate Line Cards • x = slot number (1 through 8) • Single Small Form-factor Pluggable (SFP) interface • AT-SP series SFPs from Allied Telesyn • Rate adaptive from 100Mbps through 2.7Gbps • Rate displayed in management menu • Color-coded and numbered for appropriate slot • Each line card transmits and receives the same wavelength • Individual LED set per line card • Monitors Line sync, Line Tx, Line Rx, Tributary Tx, Tributary Rx, and line card Ready • Alerts user via LED behavior if line card is inserted into an incorrect location

  12. LightExplorer Line Cards • Each AT-LX3811 line card supports rates from 100Mbps through 2.7Gbps (inclusive) • Installed SFP must support desired rate • AT-SP2670 Series support multiple data rates • Line card is protocol agnostic • AT-LX3800U management detects tributary speed T1/E1 over Fiber SONET SDH ATM Fiber Channel Fast Ethernet Gigabit Ethernet ESCON AT-LX3811 Line Card CWDM wavelength for transport SFP

  13. LightExplorer: AT-SP series SFPs Similar to AT-G8 GBICs, in SFP form factor • Multi-mode fiber (SX) • Single-mode fiber (LX10, LX40, ZX80, CWDM) • Digital diagnostics for enhanced management of the tributary interface performance • LC connectors • Bail latch design for easy installation and removal • Fiber Channel and GbE support: • AT-SPSX, AT-SPLX10, AT-SPLX40, ATSPZX80, AT-SPZX80/xxxx (xxxx = CWDM wavelength) • Same SFPs planned for use in new SFP-based 8500, 8900, 9400, 9900 series switches • Multi-rate (155Mbps – 2.7Gbps) options under the AT-SP2670 naming convention
