Transceiver
(J4860C)
A small form-factor
pluggable (SFP) Gigabit LH
transceiver that provides a
full-duplex Gigabit solution
up to 70 km on single-
mode fiber.
Ports
1 LC 1000BASE-LH port (no IEEE standard exists for 1550 nm optics); Duplex:
full only
Physical characteristics
Dimensions: 2.17(d) x 0.60(w) x 0.46(h) in. (5.5 x 1.53 x 1.18 cm)
Weight: 0.04 lb. (0.02 kg)
Environment
Operating temperature: -40°F to 185°F (-40°C to 85°C)
Operating relative humidity: 0% to 95% @ 77°F (25°C), noncondensing
Nonoperating/Storage temperature: -40°F to 185°F (-40°C to 85°C)
Altitude: up to 10,000 ft. (3 km)
Cabling
Cable type:
Low metal content, single-mode fiber-optic, complying with ITU-T
G.652 and ISO/IEC 793-2 Type B1;
Maximum distance:
10-70,000 m (single-mode fiber)
Notes
Power consumption is 0.8 watts typical with 1 watt maximum at 100%
utilization.
For distances less than 20 km, a 10 dB attenuator must be used.
For distances between 20 km and 40 km, a 5 dB attenuator must be used.
Attenuators can be purchased from most cable vendors.
