TP-Link TL-SM311LS MiniGBIC Single-Mode SFP Module: Overview
The TP-Link TL-SM311LS is a 1000Base-LX MiniGBIC single-mode SFP module for network engineers and ISPs connecting switches, routers and OLTs over fiber. It runs at 1.25 Gbps over single-mode fiber with a duplex LC connector, and supports DDM and hot-swapping.
As a duplex module, it uses two fiber cores, one to send and one to receive. It is a classic, widely used choice for gigabit fiber links between buildings or switches.
Fiber links are immune to the electrical interference and lightning-related surges that often damage long copper runs, which is one reason offices and ISPs move inter-building links to fiber. A reliable SFP module at each end is the key part of that link.
Key Features
- 1000Base-LX, 1.25 Gbps: the standard gigabit single-mode fiber specification.
- Single-mode fiber: suitable for longer runs than multimode.
- Duplex LC connector: uses a standard LC-LC duplex patch cord.
- DDM: digital diagnostic monitoring lets compatible switches show optical power and temperature, which helps when troubleshooting.
- Hot-swappable: can be inserted or removed without powering down the switch.
Best For
Gigabit links between office floors or buildings, connecting remote switches for CCTV or factory networks, and ISP distribution links on single-mode fiber where two cores are available.
Things to Check Before Buying
- Use the same type of module, or a compatible 1000Base-LX module, at both ends of the link.
- You need two single-mode fiber cores and an LC duplex patch cord for each link.
- Check that your switch has a gigabit SFP slot and accepts this module, especially if it is not TP-Link.
- Ask us about rated distance if your route is long, since it is not listed in our product facts.
- Use DDM readings on the switch to check receive power after installation.
FAQs about TP-Link TL-SM311LS
Q: How many fiber cores does it need?
A: It is a duplex module, so it uses two cores per link, one for transmit and one for receive.
Q: What is DDM?
A: Digital diagnostic monitoring. On supported switches it shows values such as optical power and temperature, which helps diagnose weak links.
Q: Can I use it with multimode fiber?
A: It is a single-mode 1000Base-LX module, so use single-mode fiber.
