As a leading expert in audio and video transmission, Beijing Onebandintong Communication Technology Co., Ltd. offers the 1310nm optical transmitter produced by Harley.
The PWL4100S from Harri is part of the PWRLink II series of 1310nm DFB laser transmitter modules. The PWRLink II transmitters are designed for advanced broadband networks, capable of being used independently in local distribution networks or combined with Harri's external modulation optical transmitter series to form a complete optical transmission network.
The PWL4100S optical transmitter features an extremely compact assembly. Within a 3U high HLP4200 platform, up to 10 modules can be inserted, which can be easily integrated into the HLP4200 platform using the HMC4001 module adapter. This optical transmitter is characterized by its intelligence and ease of setup, allowing installation and configuration to be completed in just a few minutes thanks to a user-friendly interface. The series of optical transmitters can be configured in three ways: via the menu prompts on the HLP4200WD front panel, through the RF settings on the front panel of the PWL transmitter, or using Harri's NETWatch™ network management system.
Due to its advanced pre-distortion circuitry, the PWL4100S optical transmitter offers extremely high performance and excellent distortion suppression, allowing users to achieve a high system carrier-to-noise ratio without overloading the optical receiver. With a microprocessor and firmware that monitor key functions, the optical transmitter ensures high performance and reliable operation. The monitored key functions include: laser temperature and operating current point, output optical power, and module temperature. The flat frequency response and wide operating temperature range of the optical transmitter can greatly optimize the performance of the entire broadband network.
Product Features
The innovative design of the PWL4100S series transmitters and the complete broadband system from Harri Company offer numerous advantages that meet the current and future needs of users, ensuring that Harri Company remains at the forefront of the broadband network field.
Automatic or manual gain control simplifies the operating process.
The automatic setting function has standardized the installation process.
The built-in RF preamplifier reduces the transmitter's requirements for drive level.
It can share the same broadband platform with the Harley MAXLink™ series 1550nm transmitter.
The compact structure allows for the installation of 10 DFB transmitter modules in a 3RU high platform.
Advanced predistortion circuits and methods for suppressing second-order distortion (CSO) and third-order distortion (CTB) enable the system to effectively reduce distortion over a wide temperature range.
A comprehensive network management system that is fully compatible with SNMP.
The microprocessor continuously monitors all critical parameters to ensure that the system remains in optimal operating condition.
The system, due to its wide range of specifications, can meet the requirements of specialized systems while also saving costs.
With a bandwidth of 1000MHz, it provides great flexibility for transmitting television signals and digital services. Specifically, it can transmit 80 channels (NTSC) within a 550MHz bandwidth, while the remaining bandwidth is used for transmitting digital information.
The extremely flat frequency response characteristics ensure the system's high performance and efficient integration.
The simple "plug and play" installation saves time and costs.
