Fast Light

The UTEL Fast Light system is a complete thought through solution for automating the fibre repair process and carrying out protection switching of OLT ports. The commercial benefit of Fast-Light becomes clear if one just looks at the cost of handling a single OLT port failure.

Without Fast Light, the service provider could expect up to 128 calls from customers reporting loss of service. This in itself would put a massive load on the service providers call centre and even if each call could be dealt with within 1 Minute, this would still tie up over 2 hours of call centre time! Knowing that there is a problem on an OLT port, the Repair Control would first need to work out if the problem was caused by a fibre failure or an OLT line card failure. This could require multiple truck rolls and 128 customers would be without service for hours if not days.

With Fast Light, an SNMP trap could trigger an automatic OTDR test of the fibre. Within minutes of the failure event, Fast Light would automatically identify the root cause of the failure (the OLT Port in this case) and robotically reconnect the fibre to a spare OLT port. The customer service problem is identified and resolved without human intervention before the customers even start reporting the problem.
