OLT Monitoring Software — Know Your FTTH Network Before Your Subscribers Call
OLT monitoring software for FTTH ISPs: live ONU up/down status, optical power diagnostics, EPON/GPON support, and subscriber-linked alerts — built into NowaCRM billing.
Quick answer
When an ONU goes dark, the race is on: does your NOC see it first, or does the subscriber's angry call? NowaCRM's OLT monitoring polls your OLTs over SNMP for live ONU status and optical diagnostics, and — because it lives inside your billing CRM — every alarm maps straight to a named subscriber with a phone number, a plan, and a ticket history.
Live ONU Up/Down Status Over SNMP
NowaCRM polls your OLTs for real-time ONU state — online, offline, or degraded. Support staff see the ONU status on the subscriber's own profile page, so "is my internet down?" calls get answered in seconds instead of escalating to the field team. Both EPON and GPON OLTs are supported, with a per-tenant vendor catalog so you only see the models you actually run.
Optical Power Diagnostics That Catch Fiber Problems Early
A slowly degrading optical signal is tomorrow's outage. On supported OLT models, NowaCRM reads per-ONU optical power levels so your team can spot bent fibers, dirty connectors, and failing splitters before they take a subscriber down. Diagnostics are visible right next to the subscriber record — no separate NMS login, no serial-number cross-referencing.
Alarms That Point to Subscribers, Not Serial Numbers
A standalone monitoring tool tells you "ONU MAC xx:xx is down." NowaCRM tells you "Ramesh in Sector 12, plan 100 Mbps, invoice paid, ONU offline since 14:32." Because monitoring and CRM share one database, an outage becomes a support workflow instead of a data-matching exercise — and a splitter-level failure shows you every affected subscriber in one list.
Monitoring and Billing in One Platform
Most FTTH operators bolt a separate monitor on top of a separate billing system and reconcile the two by hand. NowaCRM's OLT monitoring shares the platform with FreeRADIUS billing, GST invoicing, PPPoE/IPoE session tracking, and the subscriber portal — so uptime, sessions, and revenue live in a single dashboard.
Works With Your Existing OLT Vendors
The vendor catalog supports popular Indian-market OLTs across EPON and GPON, and new models are added continuously. All that's needed on the device side is SNMP access from your NowaCRM server — whitelist the server IP on the OLT and polling starts.
Frequently Asked Questions
What is the difference between OLT monitoring and OLT management?
Monitoring is about live visibility — ONU up/down status, optical power, alarms. Management adds provisioning workflows, splitter port tracking, and inventory. NowaCRM includes both in one platform.
Does it support both EPON and GPON OLTs?
Yes. NowaCRM polls both EPON and GPON OLTs, with a per-tenant vendor catalog covering popular Indian-market models.
Can I see optical power per ONU?
On supported OLT models, yes — per-ONU optical power readings are shown alongside the subscriber record to help diagnose fiber issues early.
What does the OLT need for monitoring to work?
SNMP access from your NowaCRM server. Whitelist the server IP in the OLT's SNMP ACL and NowaCRM starts polling — no agents or extra hardware.
