Description
FTM-9823T-CGH(i)(G) is Optical Network Termination
(ONT) triplexer for 1244/2488M Class B+ application in
ITU-T Rec.G.984.2, G.984.2 Amendment 1, and
G.983.3.
The triplexer is the high performance module for
1244/2488M data link in single fiber by using 1310nm
burst mode transmitter and 1490nm continuous mode
digital receiver with 1555nm CATV receiver.
The transmitter section uses a multiple quantum well
1310nm DFB laser, supporting power levelling with 3
modes (optional). The digital receiver section uses an
integrated 1490nm APD and preamplifier mounted in an
optical header and limiting post-amplifier IC. When the
1490nm optical power is too large, the APD protection
circuit will works to protect APD. The CATV receiver
section uses high performance analog PD and low noise
RF amplifier at 46~870MHz.
The optical burst output can be enabled by a LVPECL
differential logic high-level input BEN+/BEN-. When
BEN is high, the 1310nm output optical power will be
very low without the transmitter data in. Signal Detected
(SD) output is provided to indicate the detection of an
input optical signal of digital receiver. Flexible digital
monitoring functional is implemented by a built-in
microprocessor with I²C interface.
CATV AGC function is integrated in the triplexer, and
user can set the RF level or disable the RF output
through the I²C interface.
