从China供应商批发进口4k Uhd Optical Transceiver — FOB条款

The Cybervision CHM-4K series Ultra HD-SDI optical transceiver comprises a transmitter (CHM-4KT) and receiver (CHM-4KR) pair designed to carry one channel of 4K UHD-SDI video or four channels of 3G UHD video over optical fibre. It supports downward compatibility with SD-SDI signals at bit rates of 143, 177, 270, 300 and 1485 Mbps, and integrates a jitter-reduction circuit at the receiver to handle distorted signals. The system provides automatic signal balancing for up to 120 m at 3G Mbps or 250 m at 270 Mbps using Belden 8281 cable, with a built-in distribution amplifier on the CHM-4KR offering two-channel output.

Both units conform to SMPTE standards including SMPTE424M for 4K, SMPTE292M for HD-SDI and SMPTE259M for SD-SDI, and the transceiver has passed SDI pathology testing per SMPTE178. The front panel includes an LCD displaying optical interface type, laser wavelength, transmitting and receiving optical power, working temperature, input and output signal status for each channel and dual power supply voltage. Typical optical wavelengths for such transceivers are 850 nm for multimode or 1310/1550 nm for singlemode fibre, with standard optical power budgets ranging from -9 dBm to -23 dBm depending on distance and fibre type.

This solution is suited to live broadcasting applications where stable long-distance transmission of 4K or 3G-SDI signals is required. Broadcasters, AV integrators and production studios use it to extend signal reach beyond copper cable limits while maintaining signal integrity. The dual power supply option allows redundant backup, and the SNMP and web monitoring support enables remote network management for large-scale deployments.

Cybervision Electro-Tech Co., Ltd is based in Shanghai, China, with its registered office at Rm. 720, Building A, No. 1355 Chengbei Road, Jiadi. The company specialises in optical transmission solutions for professional AV and broadcast markets. Its product range includes SDI optical transceivers, fibre optic extenders and signal distribution equipment designed for high-bandwidth video applications.

The supplier holds a Harbor trust tier on the platform, indicating a verified business presence. While the listed response rate is currently zero, the technical depth of its product descriptions suggests a focus on engineering-led solutions rather than sales-driven engagement. The profile does not disclose certifications, production capacity or lead times, so buyers should confirm these details directly with the supplier.
