Description

The Tellabs FlexSym^® BOLT Optical Line Terminal (FlexSym BOLT) is a multipurpose Optical Line Terminal (OLT) enabling open, simple, and scalable connectivity for wired and wireless access over fiber. It supports multiple technologies, massive bandwidth, and in a compact form factor, enabling flexible design options for both fixed and mobile connectivity. FlexSym BOLT has distributed optical endpoints called ONTs that can be 2.5 gigabit GPON, or symmetrical 10 gigabit XGS-PON. With Uplink interfaces at 10G, 40G, and 100G Ethernet. ONT UNI Ethernet ports support 1G, 2.5G, 5G, and 10G, depending on ONT type. It’s an open OLT switching platform offering any management, any speed, across extended reach, using any technology in an all-optical architecture.

Features

The BOLT OLT supports the following features:

ZTP- Zero Touch Provisioning
- Zero Touch Provisioning (ZTP) speeds installation, allowing touchless install for properly configured networks. Rack and stack without ever logging in.
Stacking of OLT Power Systems
- Utilize a single pair of power supplies to power a total of 4x BOLTs in a stack and save on power supply costs.
Open Architecture
- FlexSym BOLT has a high-performance Intel processor that allows for the support of future technologies. It is delivered with an 8-core processor enabling more cost-effective solutions today, and supports a path to 16 cores for future proofing and investment protection (e.g. future routing, firewall, and SDN capabilities).
Simplified Management
- FlexSym BOLT offers all the management options that IT staff expect. It has integrated management with client-based, web-based and industry-accepted CLI options via Panorama EMS. It has open APIs and standards-based SDN, including NetConf API interfaces. The Zero Touch Provisioning (ZTP) function allows for faster provisioning and recovery.
Greater Scalability
- There are four QSFP+ interfaces that support 40 gigabits and two QSFP28 interfaces supporting 100G. The FlexSym BOLT is also equipped with four SFP+ slots, allowing the use of 10G or 1G modules.
- The PON modules can be configured for a 2.5G G-PON, or a symmetrical 10G XGS-PON on a per port basis. FlexSym BOLT provides massive uplink bandwidth to aggregate other OLTs in the stack, and also to aggregate other networks with up to 300 gigabits of non-blocking sustained switching capacity.

LED Behavior

LED		Comments
QSFP+ / QSFP28 – Each QSFP utilizes a single LED when in 40G or 100G mode. The leftmost LED indicates the status of the entire link. All 4 LEDs are used when the QSFP is in 4x Split mode to give the state of each link.	Dark	The corresponding link/lane of the four QSFP lanes is not linked up.
	Green Solid	The corresponding link/lane of the four QSFP lanes is linked up to the far end.
	Green Blink	The Port/Lane is linked and passing traffic.
STAT - Board Status LED	Green Solid	The board is operational and in service.
	Green Blink Fast	(Initializing) – The LED blinks at a ½-second (½ second on, ½ second off) duty cycle to indicate the card is currently in the process of initializing.
	Green Blink Slow	(Downloading) – ED blinks on a 1-second duty cycle (1 second on, 1 second off). The LED blinks slowly to indicate a software download in progress.
	Red Solid	The board has failed the power-up self test or has detected a hardware fault and must be replaced.
PON Low Sig – Indicates the optical status of uplink ethernet ports.	Green Solid	All ranged ONT serial numbers are above the SD threshold. This LED does not indicate the state of any missing or unexpected ONTs. The intent of this state is to indicate that the optical quality is good for all ranged ONTs.
	Amber Solid	One or more Ranged ONT serial numbers have crossed the SD BER threshold. This state indicates that for the ranged ONTs, maintenance is required on the PON.
	Red Solid	All provisioned ONTs are below SF. This can be measured by all being in a failed/LOPL-LOS state. The intent is that this LED goes red when there is no received signal on the PON or all receive signals are below SF.
	Dark	There are no configured ONTs on the PON or the PON is disabled.
PON Link – Indicates the connection status of uplink ethernet ports.	Green Solid	All provisioned ONT serial numbers are ranged on the PON and there are no unexpected ONTs. The state of the PON is good.
	Yellow Solid	At least one provisioned serial number exists and is failed (LOPL-LOS) or; one or more unexpected ONTs have been detected on the PON.
	Red Solid	All configured ONTs have failed.
SFP+ Link – Indicates the optical status of uplink ethernet ports.	Green Solid	When the SFP+ Link LED indication is solid green, the port is linked up and no data is detected on the port.
	Green Blink	When the SFP+ Link LED indication is green, the port is linked and is passing traffic.
	Dark (Off)	When the SFP+ Link LED indication is dark (Off), the port is unconfigured, or the port is failed.
SFP+ Low Signal – Indicates the power status of uplink ethernet ports.	Dark (Off)	When the SFP+ Low Signal LED indication is dark (Off), the port is disabled or the laser is receiving light and the signal level is above the LOS threshold.
	Amber Solid	When the SFP+ Low Signal LED indication is amber, the received laser signal is below the LOS threshold.
