1.25 Gbps SFP transponder

Compact and cost-effective optical Transponder Module for Applications up to 1.25Gbps

  • Protocol and rate transparent (100 Mbps–1.25 Gbps)
  • Ideal for IP, SDH, video and storage applications
  • Flexible and cost-optimized C/DWDM service module (SFP-based) or basic media converter
  • Distances: Up to 40km without signal regeneration
  • Small footprint: only 1-slot in the 19” SPEED-CARRIER platform
  • SPEED-SINGLELINE - an active Transponder Module for xWDM Networks

    The SPEED-SINGLELINE SFP is a multifunctional and compact 2-port SFP module for the universal use in telecommunication networks. The main field of application is cost-optimized CWDM and DWDM networks where the SPEED-SINGLELINE SFP, as an intelligent transponder module, converts a transparent data channel to a corresponding CWDM/DWDM wavelength. The module can be managed locally via Telnet (SNMP) or CLI interface and through SNMP or web by using the optionally available management module.

  • Media/Interface Converter in a Standalone Housing

    The SPEED-SINGLELINE SFP can be used as a protocol transparent electrical-to-optical interface converter in e.g. SDH (STM-1), IP (Fast Ethernet, Gigabit Ethernet) or Storage (ESCON, FICON, Fibre Channel) networks.

  • One Application transmitted via a single Pair of Fiber without xWDM Multiplexer

    This module is ideally suited for implementation in purely optical network infrastructures to convert among various fiber types (multi-mode/single-mode) and wavelength (e.g. 1310nm to 1530nm) while any protocol (e.g. IP, SDH, video or storage) starting from 100 Mbps up to 1.25Gbps is supported. In addition a single fiber transmission can be accomplished by using bidirectional transceivers.
