Canary builds on our experience with economical, simple to deploy, Coarse Wavelength Division Multiplexing systems by adding Dense Wavelength Division Multiplexing (DWDM) that enables up to sixteen additional data channels to be transported on top of existing CWDM data streams. Network access is easily increased to accommodate growth or expanded services.

Combined CWDM-Plus-DWDM versions mix DWDM channels with CWDM transport. This gives a user the flexibility to exactly specify the number of channels at the outset to maximize access at minimum cost when the number of CWDM channels is in-sufficient or, planned and un-planned future system growth needs to be accommodated.

Single-Fiber Bi-Directional CWDM Multiplexers are typically limited to four channels. Canary Combined CWDM-plus-DWDM versions support three CWDM and up to eight DWDM channels.

DWDM only, Multiplexers are externally connected to one or two existing CWDM multiplexer ports for easy channel expansion. Alternatively, they can be deployed as dedicated DWDM channel devices.

Canary CWDM/DWDM products are designed to be compatible with other Optical WDM equipment deployed in installations without EDFA regeneration.

For legacy interfaces, Active 100 Mbps to 2.7 Gigabit Multi-Rate Transponders are available with SFP CWDM and DWDM transceivers.

Canary Communications is an industry leader in providing advanced and economical connectivity solutions for the evolving network.

Features:

• Mixed CWDM and DWDM Multiplexers:
  Single-Fiber Bi-Directional Multiplexers with combined CWDM-plus- DWDM versions support three CWDM and up to eight DWDM channels for a total of eleven channels over a single, SMF-28 Fiber strand! Versions also available for duplex Fiber.
• 4 to 8 DWDM Expansion Channels
• Standalone / Rackable Multiplexers with Up to 16 DWDM Channels
• Active CWDM / DWDM Transceivers
• 1000BASE-T
• 1000BASE-SX
• Other Protocols
• CWDM Channel Capacity Doubled By Adding DWDM:
  Drop one or two CWDM channels, externally connect/substitute groups of DWDM channels and gain up to sixteen new user connections. Easy Expansion!
• Multiple Channels transmitted over single fiber pair: Depending on equipment choices, potentially ten CWDM channels and up to sixteen DWDM channels can be supported ­ all over SMF-28 type single-mode fiber.
• Unparalleled network integration and versatility: Mixed CWDM and DWDM connections expand customer utilization of existing fiber installations and provide exactly the number of multi-channel links desired. Makes un-planned expansion. Supports un-amplified seventy-kilometer links.
