L101P Single-Port GPON OLT: The Ideal Solution for Lightweight Access

1. L101P Product Overview

The L101P is a compact single-port GPON Optical Line Terminal (OLT) developed by Rayin. It fully complies with the ITU-T G.984.x international standards and Full Service Access Network (FSAN) specifications, ensuring interoperability with mainstream industry devices at the underlying protocol level.

Within its mini 1U chassis, it integrates complete uplink interfaces, a GPON service port, a full-featured management system, and carrier-grade forwarding capabilities. It enables the rapid deployment of a stable, manageable, and controllable fiber access network without the need for complex computer room supporting facilities, truly delivering "professional performance in a lightweight form factor".

2. L101P’s Advantages

Many people assume that "single-port OLT = stripped-down functionality", but the L101P dispels this misconception with its solid configuration, with every design element precisely addressing the core needs of small and medium-sized access scenarios.

2.1 Hassle-Free Compatibility for Zero-Barrier Deployment

For engineering contractors and operators, device compatibility is always the top priority. The L101P strictly adheres to the ITU-T G.984.x series of international standards and FSAN specifications, and supports standard OAM/OMCI protocols. It is not only fully compatible with mainstream brands of ONU (Optical Network Unit) terminals on the market, but also enables more convenient batch configuration, remote management, and service provisioning when paired with Rayin brand ONU devices, drastically reducing on-site commissioning and post-deployment O&M workloads.

2.2 Optimized Interface Configuration, No Waste, Just the Right Performance

The L101P’s interface configuration is perfectly tailored to the actual needs of small and medium-sized scenarios, with no redundant design, ensuring every dollar is spent on delivering real value:

· Service Side: 1 GPON port supporting a maximum splitting ratio of 1:128, with the ability to connect up to 128 ONU terminals per port and a maximum transmission distance of 20KM. This fully meets the access needs of a natural village, small and medium-sized park, or the ground-floor retail spaces of an office building.

· Uplink Side: Equipped with 2 fixed Gigabit RJ45 electrical ports and 1 optional SFP (GE)/SFP+ (10GE) port. It can meet conventional Gigabit uplink requirements, and can also expand upstream bandwidth via a 10G optical module to eliminate uplink bottlenecks during concurrent multi-service traffic.

2.3 Fanless Design for Ultimate Reliability

The entire device adopts a fanless silent design, which completely eliminates the noise, dust accumulation, and high failure rates associated with cooling fans. It can operate stably for long periods even when installed in telecom closets, corridor cabinets, or unattended outdoor sites.Meanwhile, it supports a wide operating temperature range of -20°C to +60°C, paired with 4KV lightning protection for the power supply and 1KV lightning protection for the interfaces. It maintains high reliability even in harsh environments with high temperatures, low temperatures, or unstable voltage, making it perfectly suited for complex deployment scenarios such as security surveillance and coverage in remote rural areas.

2.4 Full Carrier-Grade Software Feature Set

· Complete Layer 2 Switching Capabilities: It supports a 64K MAC address table, up to 4094 VLANs, VLAN filtering/translation, port mirroring, port isolation, storm control, and more, meeting the needs for refined network segmentation.

· Comprehensive Service Guarantee Capabilities: It supports IGMP V1/V2/V3 multicast and multi-dimensional QoS priority scheduling, providing bandwidth guarantee for different services such as HD video surveillance, video conferencing, and broadband internet access, eliminating stuttering and packet loss.

· Convenient O&M Management: It supports multiple management methods including WEB, Telnet, CLI, and SNMP, allowing even novice users to complete configuration quickly via the web interface. It also supports automatic ONT discovery, link detection, remote software upgrade, and power failure alarm functions, enabling daily O&M and troubleshooting without on-site visits.

2.5 Flexible Power Supply Options to Adapt to Diverse Deployment Environments

The L101P comes standard with a 100~240V wide-range AC power supply, and also supports an optional DC 12V power supply. It is perfectly compatible with standard computer room power supply, as well as solar DC power supply for outdoor sites and unattended scenarios, delivering unmatched deployment flexibility.

3. Perfectly Suited Application Scenarios

With its lightweight design and complete professional capabilities, the L101P covers nearly all small and medium-sized fiber access needs:

1. FTTH/FTTO Broadband Access: Ideal for broadband coverage in urban villages, rural natural villages, office building retail spaces, and small and medium-sized parks. Its ability to support up to 128 households per port perfectly matches the user scale of small and medium-sized deployments, at a much lower cost than large rack-mounted OLTs.

2. Security Video Surveillance Networking: Perfect for video surveillance backhaul in factories, parks, scenic areas, and road sections. Its 20KM long-distance transmission, wide temperature and lightning protection design, and multicast and QoS guarantees can reliably support stable backhaul for multiple HD cameras, making it the top choice for security engineering projects.

3. SOHO/Small and Micro Enterprise Office Networking: For fiber-to-the-office and fiber-to-the-desktop enterprise network deployment, its complete VLAN segmentation and user isolation capabilities help build a secure and stable office network, ensuring smooth operation of video conferencing and office systems.

4. Rapid Networking for Temporary Scenarios: For temporary broadband and surveillance networks for exhibitions, events, and temporary construction sites, its compact 1U chassis is easy to transport and deploy quickly. No complex computer room supporting facilities are required, and the network can be set up as soon as power is connected.

5. Final Thoughts

For fixed network operators, system integrators, and security engineering contractors, the core logic for choosing access equipment has always been "fit-for-purpose, reliable, and cost-efficient".

The L101P single-port GPON OLT perfects this logic: with its compact chassis and controllable cost, it delivers complete carrier-grade access capabilities, exceptional environmental adaptability, and convenient O&M experience, perfectly solving the dilemma of "large equipment being too costly, while simplified devices being unreliable" in small and medium-sized access scenarios.

If you are looking for a cost-effective, highly reliable OLT device for small and medium-sized broadband coverage or security surveillance networking, the L101P is an absolute no-brainer.
