Gigabit Fiber Media Converters –LFC series
Ordering Information
LFC-1001-SFP Gigabit Media Converter 10/100/1000Base-Tx to
100/1000Base-X SFP slot, DIP sw config., AC adapter included
LFC-1002-SFP Gigabit Media Converter 2x 10/100/1000Base-Tx to
100/1000Base-X SFP slot, DIP sw config., AC adapter included
LFC-1000-SS multi-rate Media Converter SFP slot to SFP slot, DIP sw
config., AC adapter included
Overview
The LFC 1000 series are high performance and reduced size Gigabit Ethernet
fiber media converters. Units have DIP switches for custom speed and flow
settings for strong networking flexibility. Physical dimensions have been
reduced for minimum footprint and highest density attainable in 19” rack
environment: 12 units/RU. Reliability is highly ranked with an MTBF exceeding
65,000 hours.
LFC converters support IEEE802.3u IEEE802.3z 1000Base-TX/FX protocols.
Package includes AC adapter 100-240V to DC 5V and one User Manual.
Features
•10/100/1000Base-T to 100/1000Base-X Conversion (or same rate
transparent for LFC-1000-SS model)
•Auto-Negotiation and Auto MDI/MDIX (LFC-1001/1002-SFP)
•Forward 2048 bytes (Max.) packets in switch mode (copper & fiber
port in different speed)
•Forward 9k bytes in converter mode (fiber & copper port at the same
speed)
•DIP switch settings for fiber speed (100/1000M), LPF and Flow control
•Support for Q in Q double tagged frame transparent
•Support for IEEE 802.1Q Tag VLAN pass thru
•100M to 2.5G transparent O-E-O repeater –both optical ports must
have same rate (model LFC-1000-SS)
•Installs into high density 12 slot/1RU rack mountable chassis, the LFC-
CH12 series (with options of redundant and AC or DC48 power
supplies)
DIP switch settings
Installation
1. Choose a flat secure surface with room for proper ventilation.
2. Power up the unit using the included AC adapter. Observe PWR LED
status indicating proper power to the unit.
3. Connect RJ45 UTP port using Cat5e or better cable to another Ethernet
device. Make sure the TP LED indicates proper connectivity.
4. Insert a Gigabit or Fast Ethernet rated SFP transceiver into the SFP slot.
Make sure the fiber transceiver used matches the fiber type (MM or SM)
and also matches a similar optical transceiver at the other end of the
fiber. Inspect FX LED for proper fiber link status.
Troubleshooting
1. No TP/LNK light: verify proper UTP cabling/pinout.
2. No FX/LNK light: verify fiber connectivity and fiber type. Consider
cleaning up fiber connectors and SFPs with appropriate tools. Make sure
Tx and RX ports are properly crossed between units. Make sure FX speed
is properly set on DIP sw.
3. No PWR light: Use only the AC adapter included. Make sure AC power is
available
