A small form-factor pluggable (SFP) Gigabit LX transceiver that provides a full-duplex Gigabit solution up to 10 km (single-mode) or 550 m (multimode).

Ports
1 LC 1000Base-LX port (IEEE 802.3z Type 1000Base-LX)
Duplex: full only

Physical characteristics
Dimensions: 2.24(d) x 0.54(w) x 0.486(h) in. (5.69 x 1.37 x 1.23 cm)
Weight: 0.04 lb. (0.02 kg)

Cabling
Type:

• -> Either single mode or multimode
• -> 62.5/125 μm or 50/125 μm (core/cladding) diameter, graded-index, low metal content, multimode fiber optic, complying with ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a, respectively
• -> Low metal content, single-mode fiber-optic, complying with ITU-T G.652 and ISO/IEC 793-2 Type B1

Maximum distance:

• -> 2-550 m (multimode 62.5 μm core diameter, 500 MHz*km bandwidth)
• -> 2-550 m (multimode 50 μm core diameter, 400 MHz*km bandwidth)
• -> 2-550 m (multimode 50 μm core diameter, 500 MHz*km bandwidth)
• -> 2-10,000 m (single-mode fiber)

Notes
A mode conditioning patch cord may be needed in some multimode fiber installations.

For distances between 20 km and 40 km, a 5 dB attenuator must be used.

Attenuators can be purchased from most cable vendors.
