Description
FTM-9712S-SL20(E)(G) is Optical Line Terminal (OLT)
compliant with IEEE 802.3ah™-2004 1000BASE-PX20
application.
The transceiver is the high performance module for
1.25Gbps data link in single fiber by using 1490nm
continuous-mode transmitter and 1310nm burst-mode
receiver. The transmitter section uses a multiple
quantum well 1490nm DFB laser and is CassⅠlaser
compliant product according to international safety
standard IEC-60825. The receiver section uses an
integrated 1310nm APD (Avalanche Photo Diode) and
preamplifier mounted in an optical header and limiting
post-amplifier IC. Unlike the conventional burst-mode
receiver, the receiver does not require reset pulse to
receive optical data packets with different optical
power.
The optical output can be disabled by LVTTL logic
high-level input of TX Disable. TX Fault is provided to
indicate that degradation of the laser. Loss of Signal
(LOS) output is provided to indicate the loss of an input
optical signal of receiver.
Enhanced Digital Diagnostic Monitoring Interface
(DDMI) compliant with SFF-8472 Rev 9.4 has been
incorporated into the transceivers. It allows real time
access to the transcevier operating parameters such as
transceiver temperature, laser bias current, transmitted
optical power, received optical power and transceiver
supply voltage by reading a built-in memory with I
2
C
interface. For further information, please refer to
SFF-8472 Rev 9.4.
