Sharetop OTN Optical Transmission Expansion Solution
Against the backdrop of digital transformation, government and enterprise private networks, data centers, metropolitan security systems and campus interconnection are generally confronted with bandwidth upgrade challenges. A large number of existing gigabit switches, surveillance devices and storage equipment are still in service. Full replacement of all hardware entails exorbitant costs. Scattered transmission of multiple gigabit services leads to severe waste of fiber resources. Long-distance transmission suffers from signal attenuation and frequent bit errors, while mixed networking of diverse services brings complicated operation and maintenance.
No need for overhaul and reconstruction. The Sharetop XYT-series OTN Gigabit-to-10G OTU service card features core capability of aggregating multiple gigabit channels into a single 10G line-side link. It bridges gaps between legacy and new networks. This pluggable solution meets four major requirements: bandwidth expansion, wavelength conversion, signal regeneration and unified management, making it the preferred lightweight transmission card for carriers, government & enterprise users and IDC computer rooms.
1. Multi-functional Design for Efficient Aggregation of Multiple Gigabit Services
In traditional networking, 8 gigabit services require 8 separate fiber cables, which brings cumbersome deployment and tight pipeline resources. This Sharetop OTN service card is equipped with multiple SFP client-side gigabit optical ports. It supports aggregating 8 channels of 1.25G Ethernet services into one 10G line-side link. Eight gigabit data streams are transmitted over a single fiber, greatly reducing fiber occupancy and lowering the cost of pipeline deployment and lease.
It is compatible with full-rate 100M/1000M services and supports transparent transmission of mixed services including switches, 4K high-definition surveillance, NAS storage, government dedicated lines and industrial collection data. Without modification to original service protocols and ready for plug-and-play, existing gigabit devices can be retained to achieve smooth network evolution.
2. Built-in 3R Signal Regeneration for Stable, Error-Free Long-Haul Transmission
For cross-campus, cross-building and metropolitan transmission spanning dozens of kilometers, gigabit optical signals are prone to jitter, packet loss and bit errors over long fiber links, whereas conventional optical-electrical conversion devices lack signal recovery capability.
The Sharetop OTN Gigabit-to-10G card integrates professional 3R regeneration (Retiming, Reshaping, Reamplification) and CDR clock and data recovery functions. It restores degraded optical signals on links and drastically reduces CRC bit errors, ensuring reliable operation of high-priority services such as financial dedicated lines, high-definition video and real-time industrial control. The single-link transmission distance can easily reach over 80 km without extra repeaters.
It also supports intelligent wavelength conversion. Ordinary client-side gigabit optics at 850/1310 nm can be converted into standard CWDM/DWDM colored optics for direct connection to WDM and OTN transmission platforms. Multiple 10G services can be multiplexed on one fiber to seamlessly expand backbone transmission bandwidth.
3. Intelligent End-to-Link Monitoring to Streamline Computer Room O&M
Manual port-by-port troubleshooting is no longer required. Equipped with DDM digital diagnostic monitoring, the card collects real-time key parameters including transmit power, receive sensitivity, temperature and voltage of each optical module. Early warnings are triggered upon abnormal link loss, boosting fault location efficiency by 90%.
Multiple management channels are available: web-based visualized graphical network management, SNMP and CLI for remote configuration. It supports remote port enable/disable, automatic laser shutdown for power saving, port VLAN isolation and independent service switching. Service provisioning, fault diagnosis and bandwidth adjustment can be completed remotely without on-site commissioning, significantly cutting on-site O&M manpower.
4. Carrier-Grade Industrial Quality for Stable Deployment in All Scenarios
Modular pluggable design: Compatible with Sharetop 1600/2000 series standard OTN chassis. Hot-swappable replacement can be performed without power cut, so expansion and upgrade will not interrupt services.
Wide-temperature stable operation: Operating stably within the industrial temperature range of -10°C to 70°C, suitable for long-term deployment in computer rooms, outdoor weak-current boxes and base station edge nodes.
Low power consumption and lightweight: Single-board power consumption ≤30W with no extra heat dissipation pressure, reducing cooling energy consumption of computer rooms for eco-friendly operation.
Multi-level link protection: Compliant with OTN-standard SNCP service protection, automatic switching completes within 50 ms upon failure to guarantee uninterrupted core services for government, finance and security sectors.
5. Application Across All Industries to Address Real Networking Pain Points
Government and Enterprise Campus Private Network Interconnection Aggregate gigabit dedicated lines from government branches, industrial parks and subsidiaries to uplink to the core computer room via one 10G fiber, saving metropolitan fiber lease fees and supporting simultaneous transmission of video conferencing, office intranet and security surveillance.
Smart City Security Backhaul Concentrate massive 4K gigabit cameras on roads and campuses. Multiple video streams are aggregated and transmitted over long distances to the monitoring center via 10G fiber with smooth and delay-free images, meeting the requirements of large-scale networking for safe city projects.
Small and Medium-sized IDC Interconnection Aggregate gigabit ports of servers and storage devices in computer rooms for 10G uplink, realizing low-cost bandwidth upgrade and adapting to low-latency data interaction for private clouds and distributed storage.
Carrier Metropolitan Edge Access Lightweight OTN expansion for mobile, radio and television, and government & enterprise dedicated lines. Service cards can be inserted to aggregate gigabit user services onto the backbone WDM network without replacing the whole transmission system, shortening project delivery cycles.
Intelligent Manufacturing Factories Long-distance transmission of high-speed visual inspection equipment and PLC industrial control gigabit data in workshops. 3R regeneration guarantees loss-free real-time industrial data transmission and adapts to complex electromagnetic interference environments in factories.
6. Independent R&D Strength of Sharetop to Support One-Stop Transmission Solutions
Sharetop has specialized in optical communication transmission for more than a decade. Its full range of OTN, WDM and OTU cards are independently developed and manufactured. Both hardware and software of this Gigabit-to-10G service card are self-developed. Customization of port quantity, transmission distance and wavelength specifications is supported. It can be matched with optical amplification, dispersion compensation and WDM multiplexing cards to build a complete end-to-end OTN transmission system.
Compared with imported transmission cards, it delivers equivalent performance at substantially lower procurement and O&M costs. We provide 7×24-hour technical support, site survey and on-site commissioning services to accelerate implementation of projects ranging from small and medium-sized deployments to large metropolitan area networks.
