cOS Loop covers the whole subscriber lifecycle on equipment from any vendor: turn service up, catch degradation early, resolve it remotely. Once the loop is closed, recurring work runs on automation rather than a technician's day, so your team's time goes to expanding the network instead of maintaining it.

Multi-Vendor PON Network Management
cOS Loop brings automated provisioning, remote diagnostics and efficient subscriber management into one operation across any vendor's PON, from the OLT to the subscriber's Wi-Fi and router. Keep the OSS, BSS, ERP and CRM you already run, connected through open APIs.
Provision. Diagnose. Manage. Automate.

Speed up fiber expansion across every vendor's PON
Your fiber estate spans a dozen equipment makers, and the systems that provision it were never designed to span them. cOS Loop puts provisioning, diagnostics and subscriber management behind one operation, whoever made the hardware. Expansion runs on the best-of-breed equipment you already have.
One operation, every vendor
Twelve or more OLT and ONU vendors sit behind one platform. Vendor-agnostic by design, so a new vendor is a configuration rather than a project.
Faster activations
Every activation follows the same automated path, so installs move at field pace and revenue starts on the day service does.
Remote management
Resolve most in-home faults from the care desk. The visits you do send arrive with the fault already identified, so truck rolls become the exception.
Consolidate your tools
cOS Loop brings provisioning, EMS, ACS and alarm monitoring together behind open APIs, with no rip-and-replace.

One visit, service live
Automated provisioning for OLTs and ONTs from any manufacturer.
- Technicians complete activation on site, from the app or straight from your workforce management system over open APIs
- The same configuration every time, so quality starts at installation
- A sanitized FTTH plant, with the OLT itself reporting which ONU sits on each port
- Works across market-leading OLTs and ONTs, whoever made them
- Activation flows straight into the ERP and CRM you already run
See every change before it reaches the network
Element management for Harmonic cOS OLTs, from the core down to the ONU.
- Configure without the CLI, on guided forms validated against the equipment model
- Line-by-line diff of current versus proposed commands, in under a second
- Apply only the delta or reprovision in full, with every change versioned and reversible
- Service and QoS profiles defined once on the cOS manager, applied across every vOLT
- One view from the cOS core to the ONU, with global ONU search across every chassis
Know about it before the
subscriber calls
Continuous monitoring, massive-event detection and automated campaigns across the PON, with every vendor's alarms in one view.
- Consolidated alarms from multiple vendors, in a single pane
- Automated quality scoring, so degradation surfaces early
- Historical power and signal data per subscriber for faster fault isolation
- Massive-event detection that identifies every affected subscriber at once, processed locally for speed
- Automated campaigns that correct quality issues at scale, with automatic stop if a campaign detects a risk
Configure, monitor and troubleshoot the subscriber equipment
Diagnose and resolve most in-home faults from the care desk.
- cOS Loop ACS (TR-069) for remote management of the subscriber's Wi-Fi and router
- Change Wi-Fi settings, run diagnostics and remediate remotely
- Push parameter changes across thousands of devices at once, with full logging and automatic stop safeguards
- Coverage reporting that shows which homes to act on first
Ready to accelerate fiber expansion on the systems you already run?
The fiber is in the ground. cOS Loop is how you run it as one network, across every vendor's OLTs, ONTs and subscriber equipment. Activations complete on the first visit, and most in-home faults are resolved from the care desk.
