Product Overview

The Transition Networks CETTF1012-105 is a high-performance 10Base-T to 10Base-FL converter module that bridges standard copper Ethernet with single-mode fiber optic links up to 20 kilometers. Designed for enterprise and data center environments, this compact unit delivers reliable, low-latency connectivity while maintaining the simplicity of RJ45 interfaces on one side and ST connectors on the other.

Key Features

  • Seamless integration with existing 10Base-T cabling infrastructure
  • Fiber optic reach up to 20km using Class A single-mode fiber
  • Compact, rack-mountable design for space-constrained deployments
  • Passive optical module - no power or cooling required on the fiber side
  • Robust mechanical construction with secure RJ45 and ST connectors
  • Easy plug-and-play installation; no configuration needed

Technical Specifications

  • Transmission Standard: 10Base-T (RJ45) to 10Base-FL (SMF)
  • Maximum Fiber Reach: 20,000 meters (Class A SMF)
  • Connector Types: RJ45 on copper side, ST on fiber side
  • Operating Temperature: -40 to +70 degrees Celsius
  • Power Consumption: Passive on the fiber side; standard 10Base-T power draw
  • Dimensions (WxHxD): 3.5 x 2.0 x 1.5 inches (approx.)
  • Weight: 0.4 pounds (approx.)
  • Compliance: IEEE 802.3, IEC 60794-1

Applications

  • Extending LAN connectivity across campus buildings or remote sites without running new copper cabling
  • Linking data centers separated by up to 20 kilometers while preserving existing Ethernet interfaces
  • Providing fiber backhaul for branch offices, retail locations, and industrial facilities
  • Upgrading legacy 10Base-T networks to optical backbone with minimal disruption
  • Enabling high-speed, low-latency connections in telecom and broadcast environments

This converter module offers a straightforward solution for organizations looking to leverage the speed and distance advantages of fiber optics while keeping the familiar RJ45 interface on the network side. Its passive design, robust build, and long reach make it an ideal choice for both new deployments and incremental upgrades.
