Alcatel-Lucent 3HE09437AA CFP-100G 100G Optical Module

Description

Product Introduction & Engineering Value

The Alcatel-Lucent 3HE09437AA CFP-100G is a 100G optical networking module using the CFP form factor. It is intended for high-bandwidth network equipment that supports CFP-based 100 Gb/s interfaces. The exact optical reach, wavelength, fiber type, and connector arrangement should be confirmed from the module label and platform documentation rather than inferred from the generic “CFP-100G” designation.

For replacement work, interface compatibility is critical. A CFP module must match the host equipment’s supported CFP type, optical standard, firmware requirements, and network architecture. Physical fit alone does not establish compatibility.

Technical Specifications

Important specification limitation

The designation CFP-100G establishes the 100G CFP class but does not by itself establish whether the module is LR4, ER4, SR10, or another optical implementation. Those variants have materially different wavelengths, fiber requirements, reach, and connector arrangements.

Do not populate an inventory database with a specific optical standard unless it is confirmed from the actual 3HE09437AA label or an applicable Alcatel-Lucent technical document.

Field Application & the “Trench” Experience

A 100G optic can be physically compatible and still fail during commissioning.

Consider a network migration where a failed 100G CFP is replaced during a maintenance window. The replacement seats correctly, the host recognizes an optical module, but the link remains down. The problem turns out to be an optic mismatch: the original link uses a particular fiber type and optical standard, while the replacement was sourced only because both units were described as “100G CFP.”

That is a classic procurement mistake.

For 3HE09437AA, capture the complete optical label before ordering. Record the original module’s optical standard, wavelength, reach, connector type, and host interface.

Specific application scenarios

• 100GbE aggregation links between high-capacity Alcatel-Lucent network switches.
• Data-center interconnects requiring CFP-based 100G optical interfaces.
• Carrier Ethernet backbone links where legacy CFP 100G hardware remains in service.
• High-capacity network migration projects where an existing CFP interface must be maintained rather than converted to a newer form factor.

Transparency SOP: QA & Testing

For New Surplus 3HE09437AA CFP-100G, the acceptance process should include:

1. Label verification
Confirm 3HE09437AA and the CFP-100G marking.

2. Physical inspection
Check the CFP housing, electrical contacts, optical connector, latch mechanism, and label condition.

3. Cleanliness inspection
Inspect the optical interface and protective cap. Fiber contamination can create significant insertion-loss problems.

4. Host recognition test
Install the module in a compatible Alcatel-Lucent platform and confirm that the host recognizes the optic correctly.

5. Optical test
Use appropriate calibrated optical test equipment to verify transmit and receive performance.

6. Link test
Where possible, establish a controlled 100G link using the appropriate matching optic and fiber.

7. Documentation
Record module identification, optical parameters, host platform, firmware/software environment, and test results.

A “powers on” test is not sufficient for a 100G optical transceiver.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Treating every optic as interchangeable

CFP is a form factor, not a complete optical specification. Two 100G CFP modules can have completely different optical characteristics.

PRO TIP: Put the complete optic label into the spare-parts database, including the vendor P/N, optical standard, wavelength, reach, and any coding information.

⚠️ Trap #2 — Ignoring host-side compatibility

The optic must be supported by the specific Alcatel-Lucent equipment and software release. Check the host platform’s supported transceiver list before installation.

⚠️ Trap #3 — Contaminating the optical interface

Never connect an unprotected or visibly contaminated optical connector to production equipment. Inspect and clean fiber interfaces using the site’s approved fiber-cleaning procedure.

⚠️ Trap #4 — Testing only at the management layer

A switch reporting that the optic is present does not prove that the optical link meets specification. Check actual transmit/receive performance and link stability.

Dynamic FAQ

What is Alcatel-Lucent 3HE09437AA?

3HE09437AA is identified with the designation and is associated with 100 Gb/s optical networking hardware.

Is 3HE09437AA a 100G CFP transceiver?

Yes, the supplied product designation identifies it as . The exact optical variant should still be verified from the physical label or technical documentation.

Does specify the optical reach?

No. “” describes the form factor and nominal 100G class, but it does not uniquely identify the optical reach or standard.

Can any 100G CFP replace 3HE09437AA?

No. Check the optical standard, wavelength, reach, fiber type, connector, host compatibility, and module coding before substitution.

What should I request when buying New Surplus 3HE09437AA?

Request photographs of the actual module label, including the complete 3HE09437AA number and any optical specification printed on the label. Also ask whether the optic was tested in a compatible host platform.

Does New Surplus mean the optic is unused?

Not necessarily. The supplier should explicitly state whether the module is unused surplus, used, refurbished, or repaired.

What warranty should I request?

Confirm the warranty period, exact condition, serial/part-number traceability, optical test scope, host compatibility, and return terms. For a 100G optic, ask specifically whether transmit/receive optical performance was tested, not merely whether the module was detected by a switch.
