Import 155m 1x9 Sc Bi-Directional 20km Transceiver — Buy in wholesale FOB from Supplier in China

The Etu-link Technology 155m 1x9 SC Bi-directional 20km Transceiver, listed under item number E1B35 (53) 03-5SC20, is a single-fibre bi-directional optical module designed for SONET, SDH, and PDH equipment interconnects. It uses a single strand of single-mode fibre to transmit and receive data simultaneously on different wavelengths, effectively doubling fibre capacity compared to dual-fibre modules. The module operates at a data rate of 155 Mbps over a maximum distance of 20 kilometres and terminates with an SC simplex connector.

This transceiver is housed in the industry-standard 1x9 pin-through-hole (PTH) package, making it suitable for direct soldering onto printed circuit boards within network equipment. It supports a multi-rate operation from 1 Mbps up to 155 Mbps and can be powered by either a 3.3V or 5V supply. The transmitter section uses an uncooled 1310nm or 1550nm FP laser, depending on the specific variant, and the module includes LVTTL/TTL signal detection output and Digital Diagnostic Monitoring (DDM). It is wave solderable, aqueous washable, and RoHS compliant.

Equipment manufacturers and system integrators building SONET/SDH multiplexers, PDH access equipment, or fibre-to-the-curb (FTTC) cabinets are the primary buyers for this 1x9 form factor. The bi-directional design is particularly valuable where fibre plant is limited or costly to expand. Trade terms such as MOQ, unit pricing, and lead times are not provided in the listing; buyers should request a formal quotation from Etu-link Technology that specifies these details along with the exact wavelength pairing (e.g., 1310nm Tx / 1550nm Rx) for the bi-directional variant.

Etu-link Technology Co., Ltd. is based in Shenzhen, Guangdong, China, with its facility located in the Jingxuan Industry Park on Donghuan 2nd Road. Shenzhen is a major global centre for electronics manufacturing, and the company's location within an industrial park suggests established production or assembly operations. The supplier profile lists an 'imported' tier, indicating a record of international shipments.

The listing does not disclose the company's establishment date, workforce size, annual turnover, or a portfolio of named clients. The trust tier is marked as 'harbor', and the response rate data shows 0.00%, meaning no historical response time to inquiries is recorded on this platform. Buyers seeking to verify the company's manufacturing capabilities, quality management certifications, or export history should request these documents directly from Etu-link Technology as part of their supplier evaluation process.
