Network Architectures / Solutions

In-Home Networking

Lindsay in-home networking solutions are ideal for advanced DOCSIS® 3.1 network installations in the customer premise. A variety of 1.2 GHz LRSA/LSA series subscriber amplifiers with low, mid and high upstream/downstream diplex filter options, coupled with our 1.2 GHz LBI series indoor splitters and a variety of high-pass filters, create an end-to-end, high quality connection.

MDU Solutions

Lindsay’s MDU solutions are ideal for advanced DOCSIS® 3.1 network installations in apartment buildings, hotels, schools, hospitals and other similar facilities. Start by coupling the signal from the outside plant (OSP) with our 100 series of hardline passives, which then feed our 1.2 GHz LHA / LBA / LA series of MDU amplifiers which offer low, mid and high upstream/downstream diplex filter options. Distribution to the customer is accomplished with our 1.2 GHz LBIDT multitaps and LBDT directional couplers, creating an end-to-end, high quality connection.

RFoG End-to-End Architectures

Lindsay has developed four end-to-end RFoG solutions: (1) standard RFoG architecture using our LB-1000 optical platform and LBON300AC subscriber ONU, (2) OBI-free RFoG architecture using our LB-1000 optical platform, NoBI™ OBI-free active splitter, or using our LBON320ACT OBI-free subscriber ONU, (3) Fiber to the Tap (FTTT) architecture using our OBI-free LBON820ACT ONU outdoor-hardened, 8-port optical node which allows operators to replace a coaxial cable TV multitap to extend fiber to each tap location in brownfield applications, and (4) extensions of existing HFC networks using our XTENDR™ coax to optical HFC repeater/RFoG extender in combination with Lindsay’s LBON series of mini RFoG nodes at the customer premise for customers that previously could not be reached with the traditional HFC network.

Fiber Deep HFC Architecture

Lindsay combines our LB-1000 optical platform with our LBON4200 2×2 segmentable node to place fiber deeper into the system network. RF output from the optical node feeds the coax architecture, LB-MB-120A bridger amplifiers, and LBLE-100A line extenders through to Lindsay’s LExMT series of multitaps to give a complete end-to-end hybrid fiber coax (HFC) architecture.

GPON with RFoG Overlay

Lindsay’s LB-1000 optical platform is combined with Lindsay’s Lumia G16 OLT through our LBAP-2000H EDFA/GPON combiner. The downstream 1550 nm RFoG and 1490 nm GPON wavelengths go through a Lindsay LBON520AC subscriber ONU with PON pass through port, to feed our G74 GPON ONT. Upstream from the GPON ONT is combined with the RFoG upstream and is sent back to the headend where the RFoG upstream is separated by a WDM filter to an optical receiver in the LB-1000 optical platform for a complete end-to-end solution.

Network Standby Powering Solution

The Lindsay LBUPS-900/1350 series of network standby powering solutions provide uninterruptable quasi-square wave power to the outside plant (OSP) while allowing remote parameter status monitoring and system updates via the DOCSIS® 3.0 transponder. AC power is injected into the HFC plant and is directionally controlled using the Lindsay LHI116 power inserter/status picker. Transponder telemetry is coupled into/from the plant through the LHI116’s 16 dB coupled RF-only port. Real time telemetry and alarm notification of any system faults provide instantaneous information to the operator. Fully user-programmable operating parameters allow the powering solution to be tailored exactly to the system requirements.

Network Non-Standby Powering Solution

The Lindsay LBNS-PS series of pole or wall mounted network non-standby powering solutions provide fully regulated, clean and reliable quasi-square wave power to the outside plant (OSP). The powder coated enclosure incorporates an external “output power on” LED, and is designed to be rugged and reliable to withstand the harshest environmental conditions. These power supplies have full input and output protection, current limited output with automatic restart upon removal of short or overload, and a field selectable 63 or 89 VRMS output voltage. The output is a standard hardline 5/8”-24 female connection.

NIU & CPE UPS Powering Solutions

Lindsay’s series of NIU/CPE UPS systems are easy to install, weatherproof, temperature-cycled -20°C to +55°C (-4°F to +131°F), cUL listed systems in lockable, polycarbonate enclosures. They come with either a VRLA or Li-ion-based UPS and an NIU/CPE device (cable modem, router, Wi-Fi® device, RFoG nodes, ONTs, subscriber amplifiers, etc.). These systems are designed to provide continuous, regulated, low noise power and connectivity during AC power failures. They are available with standard Lindsay or third-party devices, or can be customized to your requirements. Lindsay’s LBP-UPS-F-25-24 device is an easy to install Li-ion-based CPE standby UPS capable of delivering up to 25 W of power. Up to 33 hours of standby power are available from this microprocessor-controlled UPS, and the telemetry signals are compatible with all major brands of ONTs.

Small Cell Powering Solution

Lindsay’s small cell powering solutions provide power and data to third-party small cells utilizing the HFC network. The LBDG-400-AC-8200-2 2-port outdoor small cell gateway provides up to 400 W of constant 81-90VRMS power from the 60-90 VRMS HFC network for to up to two small cell radios. The gateway also translates DOCSIS® 3.1 data to Ethernet protocol for the small cells. Power input to each small cell is managed by a lockable (off position) LBEPO-x emergency power off lever switch. This allows service technicians to turn the small cell power off from a safe distance in accordance with the FCC human exposure to radio frequency magnetic fields policy.

HFC Business Connectivity Solutions

Lindsay’s HFC business connectivity solutions provide new revenue streams for operators by using existing infrastructure to provide backhaul and power to a wide range of IP devices. By coupling the signal from the outside plant (OSP) with our 100 series of hardline passives, Lindsay has engineered 48 VDC/90 VAC power outputs ranging from 20 W to up to 400 W. HFC powering can support DOCSIS®, optical or PON backhaul. Lindsay’s solutions are hardened to extreme conditions which ensures a high quality, reliable connection that supports small cells, Wi-Fi®, IoT, security cameras, digital signage, and street furniture deployments.
