📘 Product Overview — What is an EDFA optical amplifier?
EDFA (Erbium Doped Fiber Amplifier) Injects pump light (excitation light) into a special optical fiber containing a trace amount of erbium element, activating the erbium atoms to a high energy state, and then while the input signal light passes through this optical fiber. stimulated emissionIt is an optical-optical amplification device that generates and directly amplifies signal light.
Gyeongin Telecom KI-EDFA series 980nm high reliability pump laser diodeis adopted to amplify the optical signal as it is without converting it into an electric signal, so it can be used in CATV, HFC (Hybrid Fiber Coax), FTTH, intra-premises optical transmission network, etc. Any environment requiring long-distance optical signal transmissioncompensates for signal loss and maintains stable output.
✨ Core Features
- Diverse output lineup — 10 / 13 / 15 / 17 / 19 / 21 / 23 / 25 / 27 / 29 / 31 / 33 dBm 12-level model to secure network design freedom
- High-reliability 980nm pump LD Adoption — Guaranteed output stability even during long-term operation (improved MTBF)
- Low noise figure (NF) — Minimized SNR degradation even in multi-stage cascade configuration
- High optical gain — Amplifies input 3-6 dBm signals up to 33 dBm
- Wide operating input range — Operates under various input conditions with input optical power of 3 dBm to 6 dBm (Typical 5 dBm)
- Radio Research Agency (NRRA) type approval Existing product lines (two-way transmission amplifier KI-TW750B, etc.) — Eligible for delivery to domestic telecommunications and broadcasting operators
- Local production + own R&D — Based on signal processor and amplifier design technology accumulated over 30 years since the merged parent company, Gyeongin Telecom (1992)

💬 Core Technology FAQ
Q. In what fields are EDFA optical amplifiers used?
A. CATV (cable TV) optical transmission network, HFC (Hybrid Fiber Coax) network, FTTH (Fiber-To-The-Home) subscriber network, On-site optical distribution network It is used in all environments where optical signals must be transmitted over long distances and multiple branches. Since the signal is amplified in its optical state without being converted to electricity, there is no conversion loss and broadband processing is possible.
Q. What is the output lineup of Kyungin Telecom’s EDFA series?
A. 10 / 13 / 15 / 17 / 19 / 21 / 23 / 25 / 27 / 29 / 31 / 33 dBm Provides a 12-step output model. 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 Kyungin Telecom’s products compared to other EDFAs?
A. (1) 980nm high-reliability pump LD Excellent long-term operational stability through adoption (2) Low noise figure (NF)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 Agency (NRRA) type approval Owned product lines - Eligible for supply to domestic telecommunications and broadcasting companies.
Q. What is the recommended power range for optical input signals?
A. 3 dBm ~ 6 dBm (Typical 5 dBm) Guarantees rated output from optical input. A variety of input conditions can be supported.
Q. How do I check quotation/technical inquiry/delivery schedule?
A. Gyeongin Telecom Headquarters (032-324-9886) or email (kitelecom1@daum.net), a sales and technical representative will respond. company homepage https://www.kitelecom.co.kr You can also check other products (antenna for public hearing, main transmission device, DTM/IF on-premise transmission system, etc.).
