Leading audio and video transmission expert, Beijing Onebandintong Communication Technology Co., Ltd. supplies the MAXLink™ HLT 7706R/7806R external modulated 1550nm optical transmitter produced by Harley Company.
Harris Corporation's MAXLink™ product line is a range of optical transmitters and amplifiers designed for 1550nm transmission network applications. The MAXLink system provides an economical solution for various network applications and structures, including long-distance transmission that is not achievable with 1310nm transmitters, and fiber-dense network architectures that rely on high-power optical amplifiers. Additionally, this system is well-suited for new and future network architectures, such as redundant ring networks, broadcast transmission, and interconnections in broadband networks. The Harris MAXLink product line includes 1-RU 19” rack-mounted transmission equipment, such as 1550nm broadcast transmitters, erbium-doped fiber amplifiers, and optical switches. The standard 1-RU 19” design saves data center space and operational costs, as it does not require additional platforms or power supplies. The high-performance HLT7706R/7806R transmitters are designed for ultra-long-haul and distribution applications, capable of being amplified and relayed by optical amplifiers. In ultra-long-haul applications, a key component of the MAXLink system is the Link Extender (HLE). The HLE enables push-pull transmission over two optical fibers, thereby improving CNR by at least 3dB and CSO by at least 6dB (compared to single-fiber transmission).
• Industry-leading high-performance 1550nm transmission enhances network transmission capacity.
• The standard 1-RU19" rack-mounted design saves valuable data center space without the need for additional platforms and power supplies.
• The integrated intelligent management unit is SNMP compatible, suitable for seamless connection with various network systems.
• The microprocessor controls various parameters, ensuring stable output and optimal performance indicators and monitoring metrics from the transmitter.
• Harley's SBS (Stimulated Brillouin Scattering) suppression technology allows for a maximum input fiber optical power of up to 17dBm under ideal conditions.
• The dual optical output port accommodates diverse network structures, offering greater cost-effectiveness.
• The dual-phase complementary optical output allows the Harrier link extender to enhance the system CNR by more than 3dB.
• Harley's proprietary electronic linearization technology has been proven to be the most effective way to reduce system distortion.
Features
The technologically advanced MAXLink™ optical transmitter offers exceptional performance and a variety of features, not only optimizing broadband network performance but also saving operational costs for users.
The built-in intelligent network management responder is SNMP compatible and can communicate smoothly with various network management systems that adhere to SNMP.
The built-in microprocessor continuously monitors all critical parameters, ensuring that the optical transmitter is always operating at its optimal state.
Harley's patented SBS suppression technology offers the highest 1550nm input fiber power in the cable television and telecommunications industry, achieving smooth and continuous adjustment of SBS from 14dBm to 17dBm.
The MAXLink™ Optical Transmitter and Optical Amplifier can share the same platform rack with the Harley PWRLink series 1310nm Optical Transmitter, allowing for unified network management systems.
Tongneng achieves perfect integrated management across different devices; at the same time, it enhances the universality of the user interface and improves the utilization of rack space.
Dual optical output not only provides diversity in transmission routing but also saves operational costs for users.
The dual-phase complementary optical output allows the HLE (Hare Link Extender) to improve the system's CNR by more than 3dB.
Harley's proprietary electronic linearization technology has been proven to be the most effective solution for reducing system distortion.
The compact, modular configuration not only provides cost-effective network equipment but is also easy to back up.
The "plug-and-play" installation saves time and costs.
