Product Overview

The E2000 duplex patch cord brings the premium spring-loaded shutter connector favored in carrier networks, CATV headends and DWDM systems — the shutter seals the ferrule against dust and stray laser light the moment it is unplugged, protecting both equipment and technicians.

The push-pull latching housing achieves high packing density while maintaining exceptional optical performance: ≤0.3 dB insertion loss and ≥60 dB return loss with APC polish, making it a first choice for high-power and analog transmission links.

Duplex zipcord construction in OS2 single-mode is standard, with full jacket, length and hybrid-connector customization under our OEM/ODM program.

Frequently Asked Questions

What makes E2000 connectors suited to high-power optical links?

The integrated metal shutter closes automatically on disconnect, blocking dust and containing laser emission — important for eye safety and end-face cleanliness on high-power DWDM and CATV systems.

What is the difference between UPC and APC polish?

UPC connectors have a domed end-face giving return loss ≥50 dB — ideal for most Ethernet and data links. APC connectors are polished at an 8° angle for ≥60 dB return loss, preferred for PON/CATV, RF-over-fiber and other reflection-sensitive systems.

Are the patch cords tested before shipment?

Every assembly undergoes 100% optical inspection plus insertion- and return-loss testing to IEC, TIA/EIA and Telcordia standards. Test reports are available on request.

Can length, color, jacket and connectors be customized?

Yes — length, jacket color and material (PVC / LSZH / OFNP / OFNR), cable diameter (0.9 / 2.0 / 3.0 mm) and any connector combination are OEM/ODM customizable.

What are your MOQ and lead time?

Standard configurations ship in 3–7 days with flexible MOQ. Custom OEM/ODM runs are quoted per project — send us your specs for a fast quotation.
