2.7 Wiring the Fiber Ports (only JetNet 3810Gf)
JetNet 3810Gf equips 2 gigabit SFP fiber ports. The speed of the SFP port supports up
to 1000Base-SX/LX. The SFP ports accept standard MINI GBIC SFP transceiver. But, to
ensure system reliability,
Korenix recommends using the Korenix certificated
Gigabit SFP Transceiver.
The certificated SFP transceiver includes 1000Base-SX/LX
single/multi mode ranger from 550m to 80KM.
The way to connect the SFP
transceiver is to plug in SFP fiber transceiver fist. Cross-connect the transmit channel
at each end to the receive channel at the opposite end as illustrated in the figure
below.
Note: This is a Class 1 Laser/LED product. Don’t stare at the Laser/LED Beam.
Note:
100Base-FX SFP transceiver is optional and can be supported by different
settings
2.8 Connecting Powered Device (PD)
Port 1 to port 8/4 provide PoE inject function with maximum 15.4w ability to power
up the powered device use the straight or cross-over Ethernet cable.
The JetNet3810G(f)/ 3806G/ 3710G follow the IEEE802.3af Alternative B mode
connector assignment. The following table shows pin assignment of alternative A and
B for the PSE ( Power Source Equipment).
