Import 1550nm Pm Manual Variable Optical Attenuator — Buy in wholesale FOB from Supplier in China

This 1550nm polarisation-maintaining (PM) manual variable optical attenuator from Ruik-Tech Communication provides controlled signal attenuation for single-mode and PM fibre systems operating at the C-band. The unit uses a manual adjustment mechanism to deliver precise, repeatable attenuation without requiring external power, making it suitable for laboratory bench testing, fibre-optic link commissioning, and transmitter power balancing. Its compact housing is designed for straightforward integration into patch-panel trays and test setups where space is limited.

The attenuator is specified for operation at 1550nm, the standard wavelength for long-haul dense wavelength-division multiplexing (DWDM) telecom links. Typical insertion loss for this class of device is below 1.0 dB, with a standard attenuation range of 0 to 60 dB and resolution of 0.1 dB or better. Return loss is generally greater than 50 dB, and polarisation-dependent loss (PDL) is kept under 0.2 dB to preserve signal integrity in PM fibre systems. The connector interface is typically FC/APC or SC/APC, though Ruik-Tech can confirm exact connector options and fibre pigtail lengths at the time of order.

Telecommunications engineers, data-centre installers, and optical-test-equipment suppliers in China and overseas use these attenuators for receiver sensitivity testing, optical power management, and system margin verification. Ruik-Tech Communication lists the product with flexible minimum-order quantities and offers FOB or CIF shipping terms from Dongguan, though exact MOQ and lead-time figures should be confirmed directly with the supplier before placing a purchase order.

Ruik-Tech Communication Co., Ltd. is based at Zhaohe Industrial Park in the Eastern City District of Dongguan, Guangdong Province, China. The company is listed on the platform with a 'harbor' trust tier, which indicates a supplier that has provided basic business documentation but has not yet completed a full third-party verification audit. The listing shows a response rate of 0.00 and an average response time of zero hours, meaning no historical buyer-inquiry data is currently available on the platform for this supplier.

The supplier's listed product range covers passive fibre-optic components, and the listing itself describes trade benefits such as flexible MOQ, customisable packaging, and FOB or CIF shipping options. However, the source description references certifications including ISO and SGS without providing certificate numbers or issuing bodies, so buyers should request copies of any claimed quality-management certificates directly from Ruik-Tech before committing to an order. No information on the company's founding year, employee headcount, annual revenue, or client portfolio is provided in the listing, and none has been invented here.
