The recommended replacement for the WS-X4148-FE-LX-MT line card is the WS-X4248-FE-SFP line card paired with GLC-FE-100LX48 optics, which supports a wider range of SFP optics such as 100BASE-FX, 100BASE-BX-D, and 100BASE-BX-U.
-
The replacement line card with SFP optics supports IEEE standards including 802.3, 802.3ah, and 802.3x flow control, suitable for fiber-to-the-desktop and metro Ethernet applications.
