Product Summary
XC
8602ME-B
outdoor optical receiver is a new
860M
Hz optical receiver. With wide
receiving optical power range, high output level, low power consumption and compact
structure. It is very easy to install. It is the ideal equipment to build the high-
performance NGB network.

Performance Characteristics
■
High responsivity PIN photoelectric conversion tube.
■
860M
Hz bandwidth design.
■
Optimized circuit design, preceding stage adopts SMT process and post stage adopts
typical module amplifier circuit, make the photoelectronic signal transmission more
smooth.
■
Power doubler output, with high gain and low distortion.
■
Optical AGC control, when the input optical power range is
-
7
~+
2dBm, the output
level, CTB and CSO basically unchanged.
■
Can be extended with remote network management, easy to access the network
management system.
■
The fiber port and network management port can be selected external (I type) or internal
(II type).

Technique Parameter
3.1 Link testing conditions
The technique parameters of this manual according to the measuring method of GY/T
194-2003 <Specifications and methods of measurement on optical node used in CATV
systems>, and tested in the following conditions.
Testing conditions:
Forward path optical receiver part: with 10km standard optical fiber, passive optical
attenuator and standard optical transmitter composed the testing link. Set
59 PAL-D
analog
TV channel signal at range of
45/87MHz
~
550MHz
under the specified link loss. Transmit
digital modulated signal at range of
550MHz
~
862MHz
, the digital modulated signal
level
(in
8 MHz
bandwidth) is
10dB
lower than analog signal carrier level. When the input
optical
power of optical receiver is
-1dBm
, the RF output level is
108dBμV
, with
8dB
output
tilt,
measure the
C/CTB
,
C/CSO
and
C/N
.
Note
: When the rated output level is the system full configuration and the receiving optical
power is
-1dBm
, equipment meets the maximum output level of link index. When the system
configuration reduce (that is, actual transmission channels reduce), the output level of
equipment will be increased.
Friendly Notice
: Suggest you setting the RF signal to
6~9dB
tilt output in the practical
engineering application to improve the nonlinear index (behind the node) of the cable system.
