Upgrading Caltech's fiber infrastructure to support next-generation network

IMSS is excited to announce the start of the Caltech fiber cable plant upgrade which includes 9 phases. Each phase includes approximately 10 buildings and running an express pathway between the core locations.

The primary objectives of this project are as follows:

  • Upgrade the fiber cable plant and replace outdated fiber cables with high-capacity cables capable of supporting ~800Gbps speeds and beyond.
  • Building and expanding fiber pathways to support above cabling installations. The additional capacity provides redundant connections for each building to the core of the network.

Each phase includes the following activities:

  • Express run between core routers
  • Fiber from each building to the tunnels
  • Network service migration to the new fiber infrastructure

2024 Implementation Schedule

  • Phase 1: In progress, expected completion end of June 2024
  • Phase 2: In progress, expected completion end of July 2024
  • Phase 3: In progress, expected completion end September 2024

MFA March update

Multi-factor authentication (MFA) is a security technology that requires multiple methods of authentication. The goal of MFA is to create a layered defense that makes it more difficult for an unauthorized person to access your account. When you use MFA, you login using your username, password, and a third factor - either a smartphone app (Duo) or a hardware token. Even if your password is compromised your account will remain secure. It is likely that you may already be familiar with MFA for handling personal accounts such as online banking, social media apps, Google, etc. At Caltech multi-factor authentication is already required for certain groups and applications and for new Caltech accounts.


  • One of the easiest and most effective ways to keep your account secure
  • Account remains protected even if password is compromised
  • Quick setup process, simple to use, and free when using the Duo Mobile app

Learn more about Multi-factor authentication (Duo) & Office 365. If you already meet the requirements and are ready to enroll in MFA for Office 365, please review the MFA Self Enrollment page for the next steps.

For questions, review the MFA (Duo) FAQs page or contact the IMSS Help Desk at 626.395.3500,, or (request type: IMSS > Duo/MFA Help).
