SFP Data Diodes
FiberPlex QSFX-100DD 100 Gigabit QSFP Data Diode Module for Uni-Directional Cyber Security

This unique QSFP Data Diode SFP Module offers uni-directional 100 Gig Speeds using 100GBASE-LR4 with 4 independent 25Gbps channels for cyber security, with single mode optics. The device transmits data in one direction without the possibility for a return path.

• Data Diode - Support single direction communication without any possibility for a return path. Acts as a Uni-Directional bridge between physically separated source and destination networks to enable data to move from a source network to a destination network without allowing access between domains.
• 100 Gigabit Operation - Supports 100G Ethernet with four (4) independent 25 Gbps wavelength lanes according to 100GBASE-LR4.
• Long Haul - Operates on single mode fiber (LC connector) and supports up to 10km link lengths.
• Hot Pluggable - Follows the Multi-Source Agreements (MSAs) Hot-pluggable Quad Small Form-factor Pluggable (QSFP28) standard.
• EMI/RFI Containment - Special milled Brass enclosure for maximum EMI/RFI containment and durability.
• ESD Protection - ESD to the Electrical PINs per MIL-STD-883 Method 3015 and ESD to the LC Receptacle as per EN 61000-4-2.
• Immunity Protection - Immunity according to EN 61000-4-3 and EMI according to FCC Part 15 Class B.
• Low Power - +3.3V Power Supply with <4.5W power dissipation.
• RoHS - RoHS compliant with RoHS 2.0(2015/863/EU)-amending.

The FiberPlex QSFX28 Data Diode provides unidirectional network connections with 100-gigabit operation.   The 100G Ethernet interface includes four (4) independent 25 Gbps wavelength channels according to 100GBASE-LR4 and offers long haul single mode fiber to 10km.

Featuring data-diode functionality, the hardware modules transmit data in one direction with no return path. There is only one optical opening to connect a single fiber.  The one direction communication does not allow any possibility for a return path.

The device works like a one-way bridge between physically separated source and destination networks to enable data to move from a source network to a destination network without allowing access between domains.

The QSFX module is hot pluggable following the MSA Quad Small Form-factor Pluggable (QSFP28) standard.  The unit uses a +3.3V Power Supply with <4.5W power dissipation and is RoHS 2.0.

A special milled Brass enclosure provides maximum EMI/RFI containment and durability.  ESD Protection is per MIL-STD-883 Method 3015 and EN 61000-4-2.  Immunity protection is according to EN 61000-4-3 and EMI according to FCC Part 15 Class B.

Data Diodes provide Network Security and Segmentation

Determining where data diodes should be deployed depends on the security goals. If the primary goal is to protect the source network, then the data diode is deployed at the edge of the security border of the source network. The data diode prevents any possibility of an external party hacking into the source network while making data available outside of the source network.

To remove all access and the possibility of data exfiltration, this 100G Data Diode QSFP provides for UDP transfer of information to a secure network or from a secure network to or from another network of lower security while preventing any data from being transmitted in the opposing direction, assured on the hardware level.  The device contains either a Receiver Optical Sub-Assembly (ROSA) or a Transmitter Optical Sub-Assembly (TOSA) allowing networks to be Senders or Receivers without allowing access.
