Product Introduction
Alcatel Lucent 3HE01616AA is a 10-port Gigabit Ethernet optical MDA used in the 7750 SR service router platform. It is a Rev B module that requires SFP optics and provides 10/100/1000 Ethernet connectivity for router expansion.
This part is usually bought by exact number because the card, optics, and chassis support all have to line up. The practical value is simple: it adds ten GigE interfaces to the 7750 SR without guessing at compatibility.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Ports stay down after install | Missing or wrong SFP optics | ✅ High | Confirm SFP type, reseat optics, check link LEDs | Install approved optics first |
| Module not detected | Bad seating or unsupported chassis | ✅ High | Reseat card and inspect slot contacts | Verify 7750 SR support and shelf fit |
| Link flaps | Fiber fault or optic mismatch | ✅ High | Swap fiber and known-good SFPs | Isolate optics before replacing the card |
| Some ports work, others do not | Failed port group or bad transceiver | ✅ High | Move optics between ports and retest | Track whether the fault follows the SFP |
| Alarm after boot | Software or provisioning mismatch | ✅ Medium | Review alarms and module inventory | Confirm platform software support |
| No traffic with link up | VLAN or service config issue | ❌ Low | Check service mapping and forwarding state | Verify network configuration first |

Frequently Asked Questions
Q: What is the Alcatel Lucent 3HE01616AA?
A: It is a 10-port Gigabit Ethernet optical MDA for the 7750 SR platform. It expands Ethernet interface capacity in the router chassis.
Q: Does it need optics?
A: Yes. It requires SFP optics, and it accepts up to ten GigE SFP modules. The card itself is not enough to bring the ports up.
Q: Is this a direct replacement for any 7750 SR card?
A: No. It only works where the chassis, shelf, and software support this exact module. Similar-looking cards are not safe substitutes.
Q: Why is it usually sold as surplus or refurbished stock?
A: Because the 7750 SR family has a long service life and many parts move through secondary markets. Price is often lower than factory supply, but compatibility still matters.
Q: Can I use 1000BASE-T copper modules on it?
A: The listing describes 10/100/1000Tx operation with GigE TX SFP support, so the transceiver choice must match the exact module and platform support. Do not assume every SFP variant will work.
Q: What should I check before ordering?
A: Confirm the part number, revision B, chassis model, software support, and the exact SFP type you plan to use. That avoids most bad buys.
Q: What is the main installation risk?
A: The common failure point is optics mismatch or unsupported chassis configuration, not the board itself. Always verify the transceiver and platform combination before deployment.
