Condition: Used

The Viavi CFP2 4x25G Electrical Adapter (BN 3076/92.90) is a high-performance active CFP2 electrical adapter designed to work with the ONT CFP2 module to test external devices such as ICs and modules based on 25/28G I/O. It provides full electrical access to the 4x25G interface and supports wideband jitter insertion, recovered clock output, dynamic skew insertion, and low-band jitter injection. Wideband jitter injection is supported on one TX lane using an external modulation signal, with a jitter modulation range of 30 kHz to 1 GHz and 2 UIpp maximum amplitude. Compatible with Port 1 only of ONT CFP2 Phy modules.

Electrical Connectors — three Huber+Suhner MXP series 8x1 cable assemblies:
• Connector 1: RX CAUI4 (4 lanes, differential)
• Connector 2: TX CAUI4 (4 lanes, differential)
• Connector 3: Auxiliary connector with jitter injection input, reference CDR Out, and TX CAUI4 (lane 3) with added jitter

Included in the sale:
• Viavi CFP2 4x25G Electrical Adapter (BN 3076/92.90)
• K1001 Cable for External CFP2 MDIO Control (for transferring MDIO signals to external eval board)
• 4x K1002 8-coax cable assemblies

The Viavi Solutions CFP2 4x25G Electrical Adapter (part number BN 3076/92.90) is an active adapter accessory designed for use with Viavi ONT (Optical Network Tester) CFP2 physical layer test modules. It enables engineers to test external devices — including ASICs, ICs, and optical modules — operating at 25G or 28G per lane electrical interfaces without requiring a pluggable optical transceiver.

The adapter provides direct electrical access to the 4x25G (CAUI-4) interface, making it suitable for physical layer characterisation, compliance testing, and development validation of high-speed SerDes interfaces. It supports wideband jitter injection on a TX lane using an external modulation signal, extending the jitter analysis capabilities of the ONT platform into the gigahertz range.
