- Product Type: 3500/22M Fiber‑Optic Transient Data Interface (TDI) Module
- Key Specs: 100Base‑FX fiber interface | Must occupy rack Slot 1 | Dynamic capture requires license ⚠️ EOL — limited stock remaining
BENTLY 133442‑01
Product Introduction
BENTLY 146031‑02 installs exclusively in rack Slot 1 adjacent to power supplies. It merges rack interface and transient‑data processing while using fiber instead of copper Ethernet to defeat electrical noise.
Compared to the copper 146031‑01 variant, this unit supports longer cable runs and rejects ground‑loop interference. It delivers 100 Mbps fiber throughput for waveform transfer —though your mileage may vary if using mismatched fiber transceiver types.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: Source traceability, serial number anti‑counterfeit check, visual inspection (no corrosion/scratches). Check edge connector pins for bending or wear.
- Live Functional Test: Power‑on self‑check, backplane comms handshake, continuous load run >24 hrs with temp logging. Capture LED status snapshots every two hours.
- Electrical Parameter Test: Insulation resistance (500 V Megger, >10 MΩ), ground continuity. Flag any resistance drift below threshold.
- Firmware Verification: Read/record firmware version, photograph DIP switch/jumper settings. Well, technically it supports pre‑trigger waveform capture, but only on firmware v4.8+.
- Final QC & Packaging: Anti‑static bag seal, QC Passed label with date. Matching terminal hardware bagged alongside the unit.

Replacement Pitfall Guide
❗ Firmware Mismatch: The unit will ignore fiber‑link configuration if host rack firmware falls below minimum revision. Older firmware only supports copper‑based TDI hardware.❗ DIP Switch / Jumper Misconfiguration: Factory defaults rarely match field settings. Pay close attention to backplane termination jumpers on the first terminal block.❗ Terminal / Cable Incompatibility: This unit uses 100Base‑FX SC fiber; copper RJ45 cables cannot work. Cross‑reference fiber mode and core size before deployment.❗ Power Supply Mismatch: Recalculate total rack power with 20% headroom. Adding this module can push marginal power supplies over their continuous rating.❗ ESD Damage: Use anti‑static mat; caution in dry environments. Static discharge can degrade fiber receiver circuitry with no visible physical damage.
Keep these in mind and you’ll cut 90% of rework time.
