Import Bidi Sfp — Buy in Bulk from Supplier in China

Atop Technology Co., Ltd supplies bi-directional SFP transceivers operating at 1310 nm transmit and 1490 nm receive wavelengths over single-mode fiber with simplex LC connectors. The Tx-1310/Rx-1490 nm configuration enables single-fiber bi-directional communication, halving fiber count in point-to-point links compared to duplex transceiver pairs. These devices conform to industrial-grade reliability standards and support high-speed data transmission for telecommunications, data center, and enterprise networking applications. The supplier operates from Shenzhen's Longgang District, placing it within China's primary electronics manufacturing corridor with established optical component supply chains.

The transceiver uses a wavelength-division multiplexing (WDM) approach with integrated diplexers to separate transmit and receive channels within a single fiber core. Laser diode specifications, receiver sensitivity thresholds, and extinction ratio performance are not detailed in the source data but are critical to link budget calculations. Typical bi-di SFP modules in this wavelength pair support distances from 20 km to 60 km depending on fiber attenuation and transmitter output power. Operating temperature range, storage conditions, and electrostatic discharge protection levels are standard parameters buyers should request from Atop Technology to confirm suitability for intended deployment environments.

Primary buyers include telecommunications carriers expanding access networks, data center operators implementing fiber-efficient architectures, and enterprise IT departments upgrading campus backbone infrastructure. Applications span GPON upstream links, metro Ethernet, base station backhaul, and cloud service provider interconnects where fiber scarcity or duct congestion exists. The simplex connector format reduces patching complexity but requires matched wavelength pairing at each link end. Buyers should confirm digital diagnostic monitoring (DDM) support, firmware compatibility with target switch platforms, and whether Atop Technology provides programming for non-standard vendor codes before committing to volume orders.

Atop Technology Co., Ltd is located in Yuanzheng Industrial Park, Longgang District, Shenzhen, Guangdong Province, a concentration zone for optical communications and electronics manufacturing. The supplier carries an 'imported' tier classification with 'harbor' trust designation, indicating platform registration without independent third-party verification. No response rate or average response hour data is available, suggesting buyers should establish direct communication channels early in the sourcing process. The company lists bi-directional SFP transceivers among its offerings but does not disclose manufacturing scope, whether production is in-house or subcontracted, or R&D staff levels.

The available profile does not state founding year, annual revenue, employee count, named clientele, or ISO certification status. The address places Atop Technology in Shenzhen's eastern industrial zone with reasonable proximity to Bao'an International Airport and Yantian Port for export logistics. Buyers are advised to request business license verification, factory audit reports if manufacturing is claimed in-house, and quality system certificates such as ISO 9001. The absence of detailed company history or scale metrics means due diligence should focus on product-level verification, sample evaluation, and reference checks with comparable telecommunications equipment buyers before volume commitments.
