OEM and customized 100G QSFP28 to 4×Duplex LC AOC solutions are available for network equipment manufacturers, system integrators, distributors, and large-scale infrastructure projects. Customization options may include cable length, OM3 or OM4 fiber selection, armored cable construction, connector configuration, labeling, product identification, packaging, and branding.

For project-based or volume requirements, compatibility can be evaluated against specific switches, routers, servers, NICs, and other networking equipment. Customers can provide the target equipment, required distance, fiber type, operating environment, cable length, and quantity for a tailored configuration.

Why does this AOC use four duplex LC interfaces?

The four duplex LC interfaces provide separate transmit and receive connections for the four optical channels of the 100G QSFP28 interface. This allows the cable to connect QSFP28 100G equipment directly to LC-terminated multimode fiber infrastructure without requiring a separate QSFP28 optical transceiver and breakout patching arrangement.

Can OM4 fiber be used with this cable?

Yes. The cable is designed for multimode fiber systems and supports up to 100m over OM4 fiber. The specified reach over OM3 is up to 70m. OM4 can therefore be advantageous when a longer 100G SR link is required within the supported application range.

What is the role of the integrated CDR?

The integrated Clock and Data Recovery circuitry helps recover and regenerate high-speed electrical signals, improving timing and signal quality between the host interface and optical components. This is particularly useful for maintaining reliable operation at data rates up to 25.78125Gbps per lane.

What does the armored construction provide?

The armored construction adds mechanical protection to the optical cable assembly, helping protect the internal fibers from external stress during routing, installation, and maintenance. It is useful in industrial environments and dense network installations where cables may experience greater mechanical handling.

Can the LC interfaces be connected directly to standard LC fiber infrastructure?

Yes. The optical side uses LC/PC pigtail interfaces, making it suitable for connection to compatible LC-terminated multimode fiber systems. Proper polarity, fiber type, and link budget should be verified when integrating the cable into an existing optical network.

Is this an industrial-temperature product?

Yes. Unlike commercial-grade versions, this model is specified for an operating temperature range of -40°C to +85°C, making it suitable for applications that may experience wider temperature variations.
