📘 Product Overview — What is an EDFA optical amplifier?
EDFA (Erbium Doped Fiber Amplifier) is This is an optical-optical amplification device that injects pump light (excitation light) into a special optical fiber with a trace amount of erbium element added, activates the erbium atoms into a high energy state, and then generates stimulated emission while the input signal light passes through this optical fiber, directly amplifying the signal light.
Kyungin Telecom's KI-EDFA series uses a 980nm high-reliability pump laser diode to amplify optical signals as they are without converting them into electrical signals, thereby compensating for signal loss and maintaining stable output in all environments requiring long-distance optical signal transmission, such as CATV, HFC (Hybrid Fiber Coax), FTTH, and intra-premises optical transmission networks.

📊 Specification
💬 Core Technology FAQ
Q. In what fields are EDFA optical amplifiers used?
A. It is used in all environments where optical signals must be transmitted over long distances and multiple branches, such as CATV (cable TV) optical transmission network, HFC (Hybrid Fiber Coax) network, FTTH (Fiber-To-The-Home) subscriber network, and in-house optical distribution network. Since the signal is amplified in its optical state without being converted to electricity, there is no conversion loss and wideband processing is possible.
Q. What is the output lineup of Kyungin Telecom's EDFA series?
A. Provides a 12-level output model of 10 / 13 / 15 / 17 / 19 / 21 / 23 / 25 / 27 / 29 / 31 / 33 dBm. There is a high degree of freedom in network design as an appropriate output model can be selected depending on the network size, number of branches, and transmission distance.
Q. What are the advantages of Gyeongin Telecom’s products compared to other EDFA?
A. (1) Excellent long-term operational stability due to adoption of 980nm high-reliability pump LD, (2) low noise figure (NF), resulting in minimal SNR degradation even in multi-stage cascades, (3) more than 30 years of CATV signal processor and amplifier design know-how inherited from the merged parent company Gyeongin Telecom, (4) domestic Radio Research Institute (NRRA) type approval product line - Korea Suitable for delivery to telecommunication and broadcasting companies.
Q. What is the recommended power range for optical input signals?
A. Guarantees rated output from optical inputs of 3 dBm to 6 dBm (Typical 5 dBm). It can respond to various input conditions.
Q. How do I check quotation/technical inquiry/delivery schedule?
A. If you contact Gyeongin Telecom's headquarters (032-324-9886) or email (kitelecom1@daum.net), a sales and technical representative will respond. You can also check other products (antenna for public hearing, main transmission device, DTM/IF in-house transmission system, etc.) on the company website https://www.kitelecom.co.kr.
