Bidirectional EDFA Amplifier (OPA, OBA) 1528-1568nm

The BEDF Series Bidirectional DWDM Optical Amplifier provides high-performance erbium-doped fiber amplification (EDFA) across the full ITU C-band (1528–1568 nm), supporting high-capacity transmission scales from 2 to 48 channels over a single fiber. Engineered for maximum slot density, the BEDF integrates two independent amplifier stages on a single board to deliver simultaneous bidirectional amplification. Specialized internal photonic components cleanly partition the spectrum, routing downstream traffic (even DWDM channels) through a high-power booster stage, while upstream traffic (odd DWDM channels) is directed through a low-noise pre-amplifier stage. The system features an advanced, software-driven “set-and-forget” Automatic Gain Control (AGC) mode that dynamically adapts pump laser profiles in real time.

Customized Managed Chassis

The RNMC is a cost-effective and flexible platform of Ethernet-controlled rack mount chassis, housing all our network pluggable modules and interfacing them through a single, user-friendly web software. It is built for high reliability and low power consumption. The modular platform simplifies building, upgrading, or expanding networks to meet the demands of today and future multi-service access requirements. It is compatible with a variety of optical layer pluggable modules, providing excellent optical performance. It can be applied to short and long distance DWDM dual-fiber/DWDM single-fiber communication links and optical cable monitoring systems to meet diverse needs across different scenarios. The chassis comes with an Ethernet management business card, cooling fan, and AC/DC power supply.

EDFA Amplifiers (OPA, OBA) 1528-1565nm

EDFA is an erbium-doped fiber amplifier. It is used to amplify the optical power up to 48 channels (channel interval of 100 GHz) or 96 channels (channel interval of 50 GHz) at the C band at the same time in the transmission link. It has characteristics of flat gain, stable output, low noise figure, etc. It is mostly used in DWDM high-speed and long-haul transmission. These Erbium-Doped Fiber Amplifiers (EDFAs) are engineered for a long operational lifespan, typically designed to function reliably for over 10 years. This durability is achieved through high-quality components and robust manufacturing processes. The design considerations include thermal management, component selection, and rigorous testing to maximize the amplifier’s longevity and efficiency.

Fiber Optical Switch

The MEMS FIBER Optical switches establish optical signal paths passively in milliseconds, supporting all data rates, and are ideally suited to manage and monitor large optical networks intelligently and remotely. The MEMS switches are reliable and have longevity suited for continuous operation. The module is designed to be housed within a management rack that can be purchased separately. The control is a net-based GUI that is compatible with standard network management protocols. The size depends on connector choice and fiber port count. A 1U management rack box front panel can house approximately 40 LC connectors (1×36). The order table includes a list of standard control interfaces. Additionally, we provide a list of commands to assist customer engineers in coding. For those who require it, we offer a code-writing service for customer interfaces at an additional charge.

LGX DWDM Mux/Demux Module

LGX DWDM is a passive module that requires no power or configuration, making it a plug-and-play solution. It is packaged in an LGX (Lucent Generic eXchange) industry-standard metal chassis or cassette designed to slide easily into rack-mount panels. Available in multiple sizes, it can also be custom-made to fit specific rack layouts. The LGX DWDM module comprises Telcordia®-compliant PLC components or thin film filters, depending on the channel count, with optimized low loss and high isolation performance. It offers wide channel bandwidth, flexible channel configurations, low insertion loss, and high isolation. Designed for both long-haul and metro access applications, this Mux/Demux module represents the state of the art in fiber optic design.

Optical Add/Drop Multiplexer (OADM)

The DWDM Optical Add/Drop Multiplexer (OADM) is a passive optical device used in WDM networks to add or drop one or multiple 100 GHz DWDM channels within the C-band onto one or two fibers, while allowing all other wavelengths to pass through to their destination without interruption. By leveraging DWDM technology, it enables efficient expansion of both existing and new networks, enhancing wavelength utilization and extending optical transmission distances. DWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) configurations, and when paired with MUX/DeMUX units at each end of the link, multiple data channels can be multiplexed and transmitted over a single-mode fiber. These passive modules can add or drop up to four channels at any point along the fiber span.

Optical Patch Cord

Optical Transport Unit (OUT)

Support 2x40G or 2x100G signal service access. The main function is to convert the 2x40G or 2x100G with 3R regeneration to 2xWDM standard wavelength signal to multiplex different WDM wavelengths to transmit in the long haul. It is mainly used in 40G or 100G transmission networks.
