Lambda Driver WDM System
Overview
The Lambda Driver series consists of multi-functional, compact and modular CWDM/DWDM systems specifically designed for metropolitan service providers and enterprises requiring a flexible, cost-effective system to multiplex, transport and switch high-speed data, storage, video and voice applications. The LD systems can create up to 64 independent virtual fiber links over a single pair of fibers over distances of up to 100km. The system supports different network topologies such as Point-to-Point, Star, Linear Optical Add/Drop Mux and Ring. Service providers and Enterprise customers deploy the LD systems to maximize the bandwidth and service flexibility of their networks.
The LambdaDriver WDM systems use a modular architecture comprising three different chassis that are rack-mountable shelf:
- LD1600 chassis can host 16 transponders plus OADMs, Muxes/Dmuxes, 1+1 redundancy, service and 2 management modules (for redundancy)
- The LD800 chassis can host 11 transponders, OADMs, Mux/Dmux, 1+1 redundancy, service module and 1 management module
- The LD400 chassis can host 5 transponders, OADMs, Mux/Dmux, 1+1 redundancy, service module and 1 management module
Modular System
- High density form factor supports
- 1 to 16 CWDM channels
- 1 to 64 DWDM channels
- Hybrid CWDM and DWDM for transparent upgrade
- The modules are hot swappable, allowing scalable, in-service expansion or channel maintenance
- Multifunctional transponders provide transparent light paths compliant to ITU-T grid CWDM/DWDM wavelengths
- A transponder module can be used in any LD family chassis
- Rate independed: protocols of all data rates in the range of 10 Mbps to 2.7 Gbps are supported
- Protocol transparent: Mix different protocols such as E3/DS3, SONET/SDH, Fast Ethernet, ESCON, Gigabit Ethernet, Fiber Channel, etc.
- Multifunction, flexible SFP access transponders (TM-xSFP)
- Special low dispersion solution for distances of up to 640 km.
- Additional loop-back and power monitoring functionalities and other diagnosis information
- High availability and redundancy using:
- Fiber redundancy protection (1+1 protection)
- O-BPSR and O-UPSR protection support
- Y-cable and transponder redundancy backup
- Sub-Rate Multiplexing. For example: Four ESCON per wavelength
- Management includes - Optical Service Channel (OSC) for secure in-band management
Passive Optical
- Single Fiber, Single Mode Fiber and Multi Mode Fiber based Mux/Dmux
- Flexible dual fiber and single fiber OADMs ranging from one to multiple wavelengths, including mix wavelengths
- Boosters, In line and Pre optical amplifiers
