Copper runs out before your network does.

When two switches sit farther apart than a LAN cable run allows, you need fiber. An SFP module adds a fiber port to a compatible switch or media converter.

Description

TP-Link Gigabit Multi-Mode SFP Module TL-SM311LM, 1000Base-SX, LC, 850nm, up to 550m

The TP-Link TL-SM311LM is a gigabit multi-mode SFP (mini-GBIC) fiber module (1000Base-SX, LC, 850nm, up to 550m). It is built for installers, integrators, IT teams and facility managers who need a genuine TP-Link product for new installs, expansions or replacements.

SFP modules plug into the fiber slots of compatible switches and media converters to create fiber-optic links. Both ends of a link must use a matching wavelength, fiber type and data rate.

Highlights of the TL-SM311LM include: Multi-Mode MiniGBIC module, Supports full-duplex; Wave Length; 850nm, Data Rate; 1.25 Gbps, Port Type; LC/UPC; Max Cable Length; 550m (1,800') using 50/125um Multi-Mode Fiber, 220m(720') using 62.5/125um Multi-Mode Fiber.

Key Features

  • Multi-Mode MiniGBIC module, Supports full-duplex
  • Wave Length; 850nm, Data Rate; 1.25 Gbps, Port Type; LC/UPC
  • Max Cable Length; 550m (1,800') using 50/125um Multi-Mode Fiber, 220m(720') using 62.5/125um Multi-Mode Fiber
  • Always keep the protective dust plug on the SFP's optical bores until you are ready to make a connection
  • Work with MC200CM with multi-mode fiber connection
