Dual 2.67 Gbps SFP 3R transponder module

Compact optical Transponder Module with 3R and Link/Line Protection

  • Protocol and rate transparent (10 Mbps to 2.67 Gbps)
  • An extremely flexible and cost-efficient C/DWDM service module (SFP-based)
  • 3R function for precise data transmission and amplification
  • Intelligent protection functionality
  • Ideal for IP, SDH, video and storage applications
  • Brocade certified
  • Protocol transparent Transmission in CWDM/DWDM Networks

    By using the SPEED-DUALLINE SFP 3R it is possible to increase the capacity of one single pair of fiber with a protocol transparent transmission of up to 96 applications (SDH, IP, Storage, video, etc.). The SPEED-DUALLINE SFP 3R performance a conversion of the standard wavelength (850 nm, 1310 nm, 1550 nm) to a dedicated CWDM or DWDM wavelength with an actively managed network termination. By utilizing of the integrated 3R functionality of the module transmission distances up to 120 km can be achieved without additional amplifier modules.

  • 1+1 Line Protection for any Kind of Protocol

    By using the optional protection function of the SPEED-DUALLINE SFP 3R, e.g. a Gigabit Ethernet application can be transfered completely redundant over a backup single-mode or multi-mode fiber optic link. Thus a 1+1 line protection with automatic switch-over time in <50ms can be realized.

  • Two Applications without external xWDM Transmission via Single Pair of Fiber

    Another field of applications for a SPEED-DUALLINE SFP 3R is the cost-effective concentration of two single-mode applications with four fiber optic uplinks for a transmission over a single pair of fiber. The fiber optic concentration can be
    accomplished in a space-saving 1-slot housing without the need of a passive xWDM multiplexer. A realization is achieved by just using bidirectional SFPs at the link side.
