Description
The OPT-1250xxxx series from DELTA is a 1X9
transceiver module designed expressly for
high-speed communication applications that
require rates of up to 1.25Gbit/sec. It is compliant
with the Gigabit Ethernet standards as well as 1x
Fiber channel standards.
The OPT-1250xxxx transceivers are provided with
the SC receptacle that is compatible with the
industry standard SC connector.
The post-amplifier of the OPT-1250xxxx also
includes a Signal Detect circuit that provides a
PECL or TTL logic-Low output when an unusable
optical signal level is detected. (see order
information)
The OPT-1250xxxx transceiver is a Class 1 eye
safety product. The optical power levels, under
normal operation, are at eye safe level.
Applications
Gigabit Ethernet/Fast Ethernet
Switched backplane applications
