Product Introduction
The JDSU 2213-7STSLKTB is a 10GBASE-LR SFP+ optical transceiver designed for high-speed data communication. It plugs directly into network switches or routers to establish fiber optic connections over long distances.This module operates at a 1310nm wavelength and supports link lengths up to 10 kilometers on standard single-mode fiber. It is engineered to meet strict industry standards (SFF-8431), ensuring reliable signal integrity and low bit error rates in enterprise and telecom environments.
Installation & Configuration Guide
Preparation (5 min)
Gather your tools. You need an anti-static wrist strap and the fiber optic cables. Check the switch compatibility list. Ensure the switch supports 10GBASE-LR modules.
Removal (If replacing)
Disconnect the fiber cables. Listen for the click. Pull the bale latch down and slide the old module out. Place it in an anti-static bag immediately.
Installation
Take the 2213-7STSLKTB out of its packaging. Hold it by the metal casing only. Align the gold pins with the switch slot. Slide it in firmly until it seats. Push the latch up to lock it.
Power-On & Test
Connect the LC fiber cables. You should hear the fan spin up on the switch. Check the port LED. It should turn green or amber depending on the vendor. Log into the CLI to verify the link status.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Action |
|---|---|---|
| No Link Light | Fiber polarity reversed | Swap the TX and RX fiber cables at one end. |
| Link Flapping | Dirty connector | Clean the fiber end-face with a click cleaner. |
| High BER | Signal attenuation | Check fiber length; ensure it is under 10km. |
| “Unsupported” Error | Vendor lock | The switch may require a specific compatibility code. |
Dimensions, Mounting & Wiring Notes
- Dimensions: Standard SFP+ MSA form factor (approx. 13.5mm W x 56.5mm D).
- Mounting: Slides directly into SFP+ cages; secured by a bale latch.
- Wiring: Uses standard Duplex LC connectors. Ensure the “TX” port on the module connects to the “RX” port on the remote end.
FAQ
Q: Is this module compatible with Cisco switches?
A: It is a JDSU/Viavi part. Most enterprise switches accept standard MSA-compliant optics, but Cisco often locks ports to Cisco-branded optics. You may need to use a compatibility command or code.Q: What is the difference between LR and SR?
A: LR stands for Long Reach (10km over single-mode fiber). SR is Short Reach (300m over multi-mode fiber). Do not mix them; the wavelengths are different.Q: Does this come with a warranty?
A: Yes, we provide a standard 1-year warranty on tested surplus hardware.Q: Can I use this for 1G connections?
A: No. This is a 10G SFP+ module. It will not work in a 1G SFP port.Q: How do I know if the fiber is clean?
A: You don’t, unless you inspect it. A dirty connector is the #1 cause of link failures. Inspect before you connect. Always.
