JW3302T 12-IN-1 Handheld OTDR 45dB 5.6″ Touch Multi-Wavelength Tester

The JW3302T redefines the handheld OTDR testing experience. The unit is compact (0.8 kg) and contains 12 fiber optic tools in one rugged handheld chassis. The high-resolution 5.6″ capacitive touch display provides instant clarity for the engineer, allowing simultaneous viewing of OTDR traces, event tables, and maps via split-screen.

Superior Performance for Any Network

Unlike standard low-range OTDRs, the JW3302T’s 45 dB maximum dynamic range plus ultra-short event dead zones of 0.8 m and 5 m at minimum pulse width across all 18 available module configurations outperform others.

FTTH crews will use the JW3302T to certify drops through 1×64 PON splitters with two stages of splitting penetration. Thanks to the Auto OTDR feature (auto-connect, auto-test, auto-generate PDF report), the engineer will not have to wait hours for results and is able to create multi-core test batches that will certify 12/24 fiber cassettes in just minutes.
Metro technicians can certify long fiber runs up to 180 km by using the JW3302T’s high-range modules. By using the event map feature, they can quickly identify splitter locations and fusion splice losses.

12 Integrated Functions – No Tool Swapping

• One-touch automated testing (Auto OTDR).
• Expert OTDR: Advanced analysis with manual control.
• WDM/Standard OPM (1310 nm / 1490 nm / 1550 nm) for live monitoring.

Standard Configuration

Applications

• FTTH: Automatic drop tests for 1×64 splits through two-stage splitters. Generate PDF pass/fail reports.
• Metro: Certify 180 km metro rings, accounting for fusion splice loss margins.
• Repair: Red light for locating jacket faults up to 10 km; OTDR will provide the exact location of the splice.
• Production: Multi-core batch testing for 24-fiber cassettes.

JW3302T – one piece of equipment provides certification, troubleshooting, and documentation for any type of fiber network, eliminating the need for multiple pieces of testing equipment.
