  Involved in deploying or maintaining fibre optic networks? Selecting the right power meter is crucial — particularly with the growing adoption of XGS-PON and Combo-PON technologies. Whether you're testing traditional GPON or the latest XGS-PON networks, mastering wavelength-specific measurements is key to avoiding costly mistakes on site. Since 2023, major telecom operators in France have been progressively rolling out XGS-PON services on their FTTH networks. This technological evolution from GPON (Gigabit Passive Optical Network) to XGS-PON (10 Gigabit Symmetric Passive Optical Network) is made possible through “Combo-PON” cards integrated into active equipment, namely: • Optical Line Terminal (OLT) – located at the network core • Optical Network Terminal (ONT) – installed at the subscriber’s premises OLTs are fitted with blades offering several PON ports, each capable of connecting multiple ONTs. Thanks to wavelength division multiplexing (WDM), a single PON port can manage passive optical trees serving several subscribers via optical splitters. Key Differences Between GPON and XGS-PON : The main driver is the increasing demand for bandwidth and data, requiring higher network throughput. Différences entre GPON et XGS-PON : • GPON technology offers up to 2.5 Gbps downstream and 1.25 Gbps upstream. • XGS-PON technology offers up to 10 Gbps downstream and upstream (Symmetric) . Modern OLTs often support both GPON and XGS-PON simultaneously through Combo-PON blades, easing subscriber migration without the need for a full infrastructure overhaul.

On PON and GPON networks, measurements are traditionally carried out by using a broadband optical power meter. This type of device measures optical power over a wide range of wavelengths but does not differentiate between specific wavelengths. Broadband power meters are factory-calibrated to measure commonly used wavelengths in PON and GPON networks (1310/1490/1550 nm). The main difference between a broadband power meter and a selective power meter lies in their ability to measure optical light over specific wavelengths. How to Choose the Right Power Meter for the Job For networks where the OLT uses XGS-PON blades transmitting at 1577 nm, a selective power meter is a must. .tg {border-collapse:collapse;border-spacing:0;} .tg td{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; overflow:hidden;padding:10px 5px;word-break:normal;} .tg th{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; font-weight:normal;overflow:hidden;padding:10px 5px;word-break:normal;} .tg .tg-1wig{font-weight:bold;vertical-align:top} .tg .tg-amwm{font-weight:bold;text-align:center;vertical-align:top} .tg .tg-0lax{text-align:left;vertical-align:top} Solution     EXFO PPM1C     Réf  19472     Viavi OLP - 37XV2    Réf 10090856 Supported Technologies   GPON, EPON, XGS-PON, 10G-EPON Simultaneous downstream for G/E-PON (at 1490nm) and XGS-PON/10G-EPON (at 1577 nm) GPON, EPON, XGS-PON, 10G-EPON Automatic detection of the active PON technology thanks to the PON-aware™ feature   Interface High-visibility backlit display with contextual keys Intuitive graphical user interface with colour touchscreen Connectivity    Low Energy Bluetooth  Low Energy Bluetooth    Power Supply   2 AA/LR6 alkaline batteries, rechargeable AA NiMH batteries, or mains power adapter Rechargeable, field-replaceable LiPo battery.

This filter blocks the 1577 nm wavelength specific to XGS-PON, allowing you to take reliable measurements only at traditional PON/GPON wavelengths (1490 nm, 1550 nm). Caution ! Adding this filter introduces additional optical loss. You will need to adjust your power readings accordingly by factoring in the average loss caused by the filter. How to Use SC or LC Reflectors with XGS-PON? Field Technician FAQ Are broadband power meters obsolete? No ! They remain essential for versatile use cases beyond FTTH — such as testing passive networks, private links, multimode fibre, or singlemode networks not migrating to XGS-PON. Can I use a blocker/reflector with my broadband power meter for XGS-PON? You can — but this won’t eliminate the risk of measurement errors or simplify workflows, as you’ll still need to adjust for the active wavelength manually. What’s the best alternative? Look for dual-mode power meters that combine broadband and selective functions. These provide a flexible, future-proof solution for both current and next-generation PON deployments.   • A broadband power meter measures the total optical signal power in a fibre, without distinguishing between wavelengths — it captures all light sources. • A selective power meter is factory-fitted with a filter that enables separate measurement of GPON (1490 nm) and XGS-PON (1577 nm) signals. This is essential for deploying and troubleshooting Combo-PON networks. This type of optical power meter simplifies testing on these networks, helps avoid errors (such as switching between GPON and XGS-PON blockers), and provides direct power readings without needing to compensate for reflector loss. p{text-align:justify;} ul li{list-style:none;} ul li span {color: #2e7c9b;font-weight: bolder;font-size: 20px;margin-right: 7px;} table{width:100% !important;margin-top:30px;} table td{border:1px solid #2e7c9b;text-align:center;} .bg_blanc.shadow h4 {text-align: center;padding-top: 15px;} h2 {font-size: 25px;margin: 15px 0px 20px 0px;} table.tg.deuxiemetableau td {text-align: center;} table.tg.deuxiemetableau {text-align: center !important;margin: 0 auto;} th.tg-1wig img {width: 40%;margin:0 auto;display: block;} .attention p {color: #c23a3a;font-style: italic;font-weight: 500;} .btn-photometre, .decouvrez-btn {background:#2e7c9b; padding: 10px;width: 35%;margin: 0 auto; margin-top: 30px; margin-bottom: 30px;border-radius: 5px;} .btn-photometre a, .decouvrez-btn a {color:#ffffff;font-weight:bolder;text-align:center;margin:0 auto;display:block;} .bg_couleur.astuce {border: 2px solid #c23a3a;padding: 10px;} img {margin: 0 auto;display: block;} .bg_blanc.shadow.faq {padding: 15px;margin-top: 35px;} .bg_blanc.shadow.faq h2 {background: #367c9a;color: #ffffff;padding: 5px;width: 30%;} .bg_blanc.shadow.faq h3 { color: grey;font-size: 17px;} .reponse {font-style:italic;} .reponse strong {color:##367c9a;} table td P { text-align: center !important;} #box-89454 { max-width: 1140px; padding-bottom: 20px; display: block; margin: 0 auto; } ...

  Site safety is an essential aspect of any construction, maintenance, or utility project. Effective safety measures not only protect workers and equipment but also ensure the welfare of the public. In the UK, Chapter 8 of the Traffic Signs Manual sets guidelines to establish and maintain safe, secure, and efficient worksites, especially when they impact public highways or transport routes. Compliance with Chapter 8 is critical in promoting road safety, reducing accidents, and safeguarding the workforce and public. What is Chapter 8? Chapter 8 of the Traffic Signs Manual provides comprehensive guidance on temporary traffic management, specifically for works on or near roads. Published by the Department for Transport, this guidance covers road signs, barriers, traffic cones, lighting, and workforce safety measures required to minimise disruptions and maintain a safe working environment. It’s designed for contractors, councils, and any entities involved in roadworks or roadside projects, ensuring that all road work setups meet safety requirements and adhere to proper standards. Key Components of Chapter 8 Compliance 1.  Traffic Signs and Signals: Proper signage is essential to inform and guide motorists and pedestrians around the worksite. Chapter 8 specifies the design, placement, and usage of temporary signs to direct traffic effectively and alert the public to potential hazards 2.  Barriers and Cones: Physical barriers such as road cones, fencing, and temporary barriers are crucial to delineating the workspace. Chapter 8 provides recommendations on spacing, positioning, and visibility to create clear boundaries between the worksite and traffic. 3.  Lighting and Visibility: In low-light conditions or at night, illuminated signage and adequate worksite lighting are required. Chapter 8 outlines standards for reflective and illuminated equipment to enhance visibility and reduce the risk of accidents in areas with limited natural light. 4.  High-Visibility Clothing: Workers are required to wear high-visibility clothing that meets Chapter 8 specifications. This is critical to ensure they are clearly visible to drivers and pedestrians, particularly in areas with heavy traffic. 5.  Pedestrian Safety: Where pedestrians may encounter the site, Chapter 8 specifies measures to safeguard them, including appropriate diversions and barriers to prevent access to hazardous areas. 6.  Emergency Access: Chapter 8 also addresses emergency access protocols, ensuring that emergency vehicles and personnel can safely and quickly navigate around or through work zones when necessary. The Importance of Chapter 8 Compliance in Site Safety 1 . Minimising Accidents and Incidents: Compliance with Chapter 8 is designed to minimize accidents, particularly those involving oncoming traffic. By following these guidelines, roadworks can be set up in a way that prioritizes visibility and safety, reducing the chances of collisions or pedestrian incidents. 2.  Protecting Workers and the Public:  Chapter 8 ensures that workers are properly shielded from passing vehicles, creating a safer environment on and around the site. It also protects the public by reducing confusion and providing clear instructions through signage and other safety measures. 3.  Ensuring Smooth Traffic Flow:  By clearly directing traffic around worksites, Chapter 8 guidelines help reduce congestion and maintain smooth traffic flow. This is essential for both public convenience and preventing additional hazards that could arise from traffic backlogs. 4.  Reducing Project Delays:  Chapter 8 compliance helps keep projects running efficiently by ensuring that road closures and diversions are well managed. This minimizes potential disruptions and prevents delays caused by non-compliance, which could result in additional inspections or even shutdowns. 5.  Legal Compliance and Liability:  Adhering to Chapter 8 is not only a best practice but a legal requirement for roadworks. Failing to comply with these standards can expose organisations to legal repercussions, including fines and liabilities in case of accidents.   For organisations involved in roadworks or any roadside projects, Chapter 8 compliance is a vital component of a broader culture of safety. This means investing in training for workers, regularly auditing sites for compliance, and using the appropriate equipment—from cones and barriers to signage that meets Chapter 8 standards. Beyond regulatory adherence, Chapter 8 creates a mindset of accountability and proactive safety, both on the worksite and within the community.  Check out our Safety Portfolio  #box-89454{display:block;margin:0 auto;} .bg_blanbc.shadow {min-height: 250px;margin-bottom: 30px;} h2{text-align:left !important;} .blanbc strong, .heighmin strong {color: #df2f33;} .bg_couleur { background: #166082; color: #ffffff; min-height: 200px; margin-bottom: 20px;} .bg_couleur strong{color: #ffffff ;} .col-lg-4.premierbloc {margin-left: 17%;} .boutonfinacik {background:#166082;width: 30%;float: none !important;clear: both;margin: 0 auto;display: block;padding: 7px;margin-top:30px;} .boutonfinacik a{color:#ffffff !important;} ...
