Product Description
The Harmonic’s MAXLink transmission system is a family of transmitters and optical amplifiers designed for 1550 nm-based network applications. The MAXLink system provides a cost effective solution for a variety of applications and architectures, including long haul applications that are beyond the reach of 1310 nm transmitters and fiber dense architectures which take advantage of high power optical amplifiers. In addition, this system is ideally suited for new, evolving transport architectures such as redundant rings, broadcast layer transmission and hub interconnects used in broadband networks. The MAXLink product line consists of plug-in modules for the HLP 4200 broadband platform, including dual output optical transmitters, models HLT 7706, HLT 7709 and HLT 7711 and Erbium-doped fiber optical amplifiers, models HOA 7014, HOA 7017, HOA 7020 and HOA 7021. The HLP 4200 broadband platform is a compact 5-1/4. high rack mount housing designed to simplify headend operation. The platform provides for plug-and-play installation and operation through a user-friendly front panel display and push-button controls. As with all Harmonic products, MAXLink modules have built-in element management capabilities. The HLT 7706 series transmitter is designed for use in supertrunk
and distribution applications where it is followed immediately by one or more optical amplifiers. The HLT 7709 and HLT 7711 with their higher output powers, is designed for supertrunking or distribution without the use of optical amplifiers, or for remote distribution where the optical amplifier is located at a distance of up
to 50 km from the transmitter. In supertrunking applications, an important component of the MAXLink 1550 nm system is the Harmonic Link Extender (HLE). The HLE provides the capability to set up a push-pull transmission architecture over two fibers resulting in a CNR boost of 3 dB or more and a CSO boost of typically more than 5 dB.

- - Microprocessor control of all key parameters provides consistent and optimum product performance and monitoring.
- - Harmonic’s unique, patented SBS suppression allows the highest launch power and performance available at 1550 nm in the cable and telecommunications industries:
- HLT 7706: up to 50 mW, 17 dBm
- HLT 7709: up to 25 mW, 14 dBm
- HLT 7711: up to 25 mW, 14 dBm
MAXLink transmitter and optical amplifier modules share a common platform with Harmonic’s PWRLink™ 1310 nm transmitter family, enabling seamless network management integration of diverse equipment, providing user interface commonality, and maximizing rack space efficiency.
- - Dual outputs provide route diversity and cost efficiency.
- - Dual complementary outputs enable push-pull operation with Harmonic Link Extender (HLE) for 3 dB or more CNR improvement.
- - Harmonic’s proprietary electrical linearization provides a proven, robust solution for optimal distortion performance.
- - Compact, modular packaging enables cost-effective network configuration and sparing.
- - Simple "plug and play” operation reduces time and cost of installation.
