从China供应商批量进口1310nm Dfb Laser Transmitter Gwt3300

The GWT3300 is a 1310nm DFB (Distributed Feedback) laser transmitter designed for transmitting analogue and digital signals over fibre-optic networks. It operates at a centre wavelength of 1310nm, which is a standard window for CATV and telecommunications, and is built to handle TV video, digital television, and voice signals with minimal distortion. The unit features a compact form factor intended for integration into existing headend or hub equipment racks, and includes built-in diagnostic monitoring for real-time signal quality assessment.

DFB laser transmitters in this class typically use an InGaAsP/InP laser diode chip, offering narrow linewidth and stable output. The GWT3300 series is described as having low power consumption and high output power, though exact figures such as optical output power (dBm), RF input level, and CNR performance are not specified in the listing. Typical specifications for 1310nm DFB transmitters in the CATV sector include output power ranging from +4 dBm to +12 dBm, frequency responses of 45-870 MHz or 45-1000 MHz, and carrier-to-noise ratios above 50 dB. Buyers should confirm the exact optical power, bandwidth, and distortion parameters with the supplier.

This transmitter is used by cable television operators, telecommunications service providers, and broadcasters for signal distribution in both urban and rural fibre networks. Applications include CATV overlay, FTTH (Fibre to the Home) video delivery, and enterprise voice/data transport. Greatway Technology Co., Ltd., based in Shenzhen, Guangdong, offers this product for wholesale purchase. Trade terms such as MOQ, Incoterms (FOB, CIF), and lead times are not listed and should be confirmed directly with the company.

Greatway Technology Co., Ltd. is a supplier based in Shenzhen, Guangdong, China, with a registered address at 6F, Building 4, South 2, Hong Hua Ling, Shenzhen 518055. The company is listed as an 'imported' tier supplier on the platform, indicating it has undergone some level of verification. However, the listing shows a 0.00% response rate and no average response time data, which means there is no recorded history of replying to buyer enquiries on this marketplace.

The product listing does not provide details about the company's founding year, number of employees, production capacity, or specific certifications beyond a general mention of ISO. No client references, export history, or factory audit information is given. Buyers interested in the GWT3300 transmitter should request documentation on the company's quality management system, product test reports, and references from previous international buyers before placing an order.
