Wholesale Premium Fiber Optic Connectors with CE RoHS ISO9001 Certification

We can do the attenuation values anywhere from 1 to 30dB, and honestly most buyers go with the 10dB for standdard telecom work or the 20dB if they're testing receiver sensitivity. The model is ST-ANT-SC5DB, it's an optical fiber attenuator with connector options covering SC, ST, FC, LC, and MU — basically whatever patch panel you're dealing with. Insertion loss is typically ≤0.3dB which is tight enough for most links, and return loss varies by polish: PC gives you ≥45dB, UPC hits ≥55dB, and APC goes to ≥60dB or so.

These things handle temperture swings from -40°C to +75°C while operating, and storage range is a bit wider at -45°C to +85°C, so they're fine for outdoor cabinets or indoor racks. The durability rating is over 1000 mating cycles, which actually matters more than people think — cheap connectors wear out after a few hundred and you get intermittent signal loss.

We've been supplying these to telco field engineers and data center guys for years, but also to labs that need precise attenuation for receiver testing or componnet characterization. They're not suited for high-vibration environments like near industrial machinery — you'd want a locking mechanism for that, but for fixed installations they're solid. One thing buyers don't always ask: the dust caps are attached, so you can't lose them in the patch panel.

OEM is pretty much standard for us — our company can do custom labeling, different packaging quantities, even your own logo on the body if the volume justifies it. Lead time is typically 20 days or so for standard orders, but we usually have stock on common values so 10-15 days is more realistic. MOQ is flexible, usually 100 pieces for custom work but we'll do smaller for repeat customers.

Body material is high-grade plastic, not metal, which keeps weight down and cost reasonable, but it still passes the 1000-cycle durability test easy. Certifications are CE, RoHS, and ISO9001 — nothing exotic, but they cover what most procurement departments need for compliance. We include a COA with each batch, and if you need HPLC data we can arrange that.

Anyway, the wavelength coverage is dual-window for single-mode at 1310/1550nm and multimode at 850/1310nm, so you're covered for both legacy and modern networks. Teh storage temp range (we usually confirm that one) matters less than operating range, but it's good to know if you're shipping to cold climates or keeping spares in an unheated warehose.
