TWO_FIBER

IPL

Two fiber ports

1: IP113F supports two-fiber ports mode. Both port 1 and

port 2 are fiber ports. RXIP and RXIM are used as

FXRDP and FXRDM for the second fiber port. TXOP

and TXOM are used as FXTDP and FXTDM for the

second fiber port.

A special requirement for the fiber MAU of port1 in this

application is that the output of FXRDP and FXRDM

should have no incoming signals when fiber is

unplugged.

For some fiber MAUs, there are amplified noisy signals

on FXRDP and FXRDM when fiber is unplugged.

These amplified noisy signals, which include coupled

idle patterns from FXTDP and FXTDM will cause the

LEDs of port1 malfunction

Generally, a 3.3-V small form factor type fiber MAUs

(e.g. Agilent HFBR-5903) can meet this special

requirement, but 5-V duplex-SC and -ST type fiber

MAUs cannot. Port2 is not limited by this special

requirement.

0: IP113F supports one fiber port and one TP port. Port 1

is a TP port and port 2 is a fiber port.
