Lantronix SFMFF1314-220 Gigabit Multimode to Single-Mode Converter
The SFMFF1314-220 is a stand-alone fiber-to-fiber mode converter that turns a 1000Base-SX multimode port into a 1000Base-LX single-mode link, extending Gigabit Ethernet or Fiber Channel from hundreds of meters to 10 km.
Overview
About the Lantronix SFMFF1314-220
Multimode Gigabit optics run out of reach at a few hundred meters, which strands switches whose ports are all 1000Base-SX when a link must cross a campus. The SFMFF1314-220 solves that on a port-by-port basis: it takes an 850 nm multimode SX signal on one SC port and retransmits it at 1310 nm on single-mode fiber from a second SC port. Used individually or in pairs, it functions as a mode converter for Gigabit Ethernet or Fiber Channel without replacing switch hardware.
On the multimode side, reach is 220 m on 62.5/125 μm fiber or 550 m on 50/125 μm fiber. The single-mode side reaches 10 km. Each side has a 7.0 dB link budget, with single-mode transmit power of -13.0 to -3.0 dBm and receive sensitivity of -20.0 dBm. The converter is protocol transparent at 1000 Mbps and supports auto-negotiation on its 1000Base-X ports, Link Pass Through, pause and automatic link restoration.
The SFMFF1314-220 (sometimes searched as SFMFF1314) runs from an external 12 VDC, 0.5 A supply and operates from 0°C to 50°C at 5% to 90% non-condensing humidity. Power, single-mode link (LKS) and multimode link (LKM) LEDs show status at a glance. Lantronix lists support for IEEE 802.3, ATM, OC-3, STM-1, HSTR and FDDI standards, and the 3.25-inch-wide housing shares mounting hardware with other Lantronix stand-alone converters.
Key capabilities
- SX to LX conversion
- Converts a 1000Base-SX multimode port to 1000Base-LX single-mode, letting existing SX switch ports reach 10 km without new line cards.
- Gigabit or Fiber Channel
- The converter handles 1000Base-SX Gigabit Ethernet or 1000Base Fiber Channel signals, and is protocol transparent at 1000 Mbps.
- Both multimode fiber types
- The multimode port supports 220 m on 62.5/125 μm fiber and 550 m on 50/125 μm fiber, covering legacy and newer multimode plant.
- Link Pass Through
- Link Pass Through and automatic link restoration propagate a fiber failure to attached equipment and recover the link when the fault clears.
- Compact stand-alone housing
- The 3.25 x 4.7 x 1 inch unit mounts with WMBD-F DIN-rail or WMBV brackets, or in RMS19-SA4-02 and E-MCR-05 rack shelves.
How to choose the right SFMFF1314-220 part number
SFMFF1314-220 is a single model with fixed optics: an 850 nm 1000Base-SX multimode SC port (220 m on 62.5/125 μm, 550 m on 50/125 μm) and a 1310 nm 1000Base-LX single-mode SC port to 10 km, each with a 7.0 dB link budget. Choose it when one end is a multimode SX port and the run needs single-mode distance. Add an SPS-2460-SA or SPS-2460-PS power supply if needed, and a WMBD-F, WMBV, RMS19-SA4-02 or E-MCR-05 for mounting.
