Dual 1.25 Gbps SFP transponder

Compact optical Transponder Module with four SFP Ports

  • 2-channel transponder module with four SFP ports
  • Protocol and rate transparent (100 Mbps to 1.25 Gbps)
  • Flexible and cost-optimized C/DWDM service module (SFP-based)
  • Optimized for IP, SDH, video and storage applications
  • Cost-optimzed optical transponder
  • Protocol transparent Transmission in CWDM Networks

    By use of the SPEED-DUALLINE SFP it is possible to increase the capacity of one single pair of fiber with a protocol transparent transmission of up to 16 applications (SDH, IP, Storage, video, etc.). The SPEED-DUALLINE SFP performs a conversion of the standard wavelength (850 nm, 1310 nm, 1550 nm) to a dedicated CWDM wavelength with a network termination which can be managed actively. The SPEED-DUALLINE SFP is a cost effective solution for transmission distances up to 40 km.

  • Media Conversion for Connecting Copper over Fiber Optic

    The SPEED-DUALLINE SFP represents a flexible solution to be used as an intelligent electrical-to-optical interface converter in e.g. SDH (STM-1), IP (Fast Ethernet, Gigabit Ethernet) or Storage (ESCON, FICON, Fibre Channel)
    networks. This module enables a completely transparent connection of e.g. copper-based infrastructures to a fiber optic line.

  • Two Applications without external xWDM transmission on a single Pair of Fibers

    Another field of applications for a SPEED-DUALLINE SFP is the cost-effective concentration of two single-mode applications with two fiber optic pairs for a transmission over a single pair of fibers. The fiber optic concentration can be accomplished in a space-saving 1-slot housing without the need of a passive xWDM multiplexer. This can be achieved by use of bi-directional SFPs at the link side.
