Sharetop XYT‑EDFA‑23 High‑Output‑Power EDFA
With the continuous upgrade of digital infrastructure, backbone optical transmission, metro WDM and private line fiber services impose increasingly stringent requirements on transmission distance, channel capacity and link stability of optical links. The design limit of an optical communication system is largely determined by the optical power budget of the entire link. Fiber attenuation, insertion loss introduced by passive WDM components, optical connectors and splitting units will continuously consume optical signal power. When the transmission distance extends and the number of multiplexed channels increases, the native power from the transmitter often fails to cover the loss of the whole link, which may easily lead to insufficient optical power at the receiver, degraded signal‑to‑noise ratio and rising bit error rate. As the core active amplification device in C‑band optical communication, the erbium‑doped fiber amplifier (EDFA) undertakes the key functions of signal power compensation and link budget expansion, and is an indispensable core module supporting long‑distance and large‑capacity optical fiber transmission.
To meet the demand for high‑output‑power amplification units in DWDM dense wavelength division multiplexing systems and various C‑band optical fiber transmission links, Sharetop presents the XYT‑EDFA‑23 High‑Output‑Power Erbium‑Doped Fiber Amplifier. Optimized for C‑band optical amplification scenarios, this product balances output power indicators, gain performance, input dynamic range and optical anti‑reflection capability, equipped with a redundant power supply architecture. It provides a reliable and well‑adapted optical power amplification solution for system integrators, optical communication engineering service providers and equipment manufacturers, supporting stable 7×24‑hour online operation.

XYT‑EDFA‑23 operates across the standard C‑band from 1529 nm to 1565 nm, perfectly matching the channel planning of mainstream commercial DWDM systems. It can simultaneously amplify multiple multiplexed signals within the C‑band without disrupting the power balance between channels, suitable for multi‑channel high‑speed service transmission. The rated gain is 25 dB, and the measured saturated output power reaches 23.05 dBm. The 23 dBm‑class high optical output provides sufficient power margin for the link, effectively compensating for fiber attenuation over long distances and insertion loss of multi‑stage passive components in the link. It helps designers break the limitation of transmission distance and simplifies the selection of front‑end optical transmitters.
Different from conventional EDFAs with narrow dynamic range, XYT‑EDFA‑23 features an ultra‑wide input optical power range of −20 to +10 dBm. In practical engineering scenarios, the optical power of upstream signals fluctuates due to front‑end device configuration, temporary link adjustment and component aging. The wide input dynamic window allows the amplifier to process incident signals with a large difference in power. It can amplify weak optical signals attenuated after long‑distance transmission as well as high‑power signals output from the front‑end multiplexer. There is no need to repeatedly adjust the upstream transmit power to adapt to the amplifier, which greatly improves the flexibility of system design and reduces on‑site commissioning difficulty.
Superior optical isolation and return loss control are critical to guarantee high‑speed signal quality. XYT‑EDFA‑23 achieves a measured return loss of 50 dB and measured input/output isolation of 50 dB. The high‑isolation design strongly suppresses back‑reflected optical signals, preventing reflected light from disturbing pump lasers, distorting signal spectra and causing gain jitter or increased noise. In complex links with cascaded devices and multiple fiber joints, its stable anti‑reflection performance continuously maintains the signal‑to‑noise ratio and reduces bit error risks, especially for DWDM systems with parallel multi‑channel transmission that are highly sensitive to optical path disturbances.
Carrier‑Grade Reliability Design
The product adopts APC (Automatic Power Control) operating mode. Under APC mode, the amplifier monitors the output optical power in real time and dynamically adjusts the pump state to keep the output power stable at the set value, avoiding significant output drift caused by variations of input optical power. This control mode is ideal for serving as a booster amplifier after the multiplexer, delivering constant and reliable optical power to the downstream transmission link. The optical interface adopts LC/UPC, the most widely used interface in computer room wiring. It offers excellent compatibility and convenient deployment, and can be directly connected to existing fiber distribution systems, WDM boards and fiber links without complicated adapters.
For reliability, XYT‑EDFA‑23 is equipped with dual wide‑voltage AC redundant power inputs of 100–240 V. Dual AC redundancy is a classic reliability configuration for carrier‑grade equipment. The two independent power inputs back up each other. If one power circuit fails or is cut off for maintenance, the other can seamlessly power the whole unit without amplifier shutdown or optical service interruption. The wide voltage input supports stable operation under normal voltage fluctuations and fits the mains environment in most regions worldwide. It is well suited for computer rooms, remote communication sites and data centers that require uninterrupted services.
Application Scenarios and Engineering Deployment Guidelines
In practical engineering planning, the deployment position and operating parameters of XYT‑EDFA‑23 shall be determined comprehensively according to overall link conditions. Before deployment, engineers need to calculate fiber attenuation, insertion loss of each passive component, upstream input signal power, target output power and receiver sensitivity. The amplifier can be placed after the multiplexer as a booster to boost launch power and extend transmission reach, or deployed as an in‑line power compensation unit depending on the link architecture. Its primary application is DWDM dense wavelength division multiplexing transmission systems, and it is also compatible with other point‑to‑point C‑band fiber transmission links. System‑level compatibility verification and overall optical power budget check must be completed before field deployment, to ensure channel power balance and receiver performance meet service requirements.
The stability of optical communication systems relies on the performance details of every active component. With high saturated output power, 25 dB rated gain, ultra‑wide input dynamic range, high isolation, low reflection design and dual redundant power supply, the Sharetop XYT‑EDFA‑23 delivers carrier‑grade C‑band optical amplification capability. More than a simple power boosting module, it helps optical systems expand power budget limits, raise transmission capacity and enhance service stability, supporting efficient and reliable implementation of new‑generation high‑speed fiber optic networks.
