SPBD-1250B4Q1R
Description
The SPBD-1250xxxx series are hot pluggable
3.3V Small-Form-Factor (SFP) Bi-Directional
transceiver module designed expressly for
high-speed communication applications that
require rates of up to 1250Mbit/sec. It is
compliant with the Gigabit Ethernet and Fast
Ethernet standards, as well as the SFP
Multisource Agreement (MSA).
The SPBD-1250xxxx transceivers provide with
the LC receptacle that is compatible with the
industry standard LC connector. The transceiver
is also compatible with industry standard RFT
connector and cage. It also includes a LOS
(Loss Of Signal) circuit that provides a TTL
logic-high output when an unusable optical
signal level is detected.
The module includes 1490nm un-cool DFB
laser, InGaAs PIN, Preamplifer and WDM filter in
a high-integrated optical assembly for
high-density system application. The SFP
Bi-Directional transceiver can upgrade
transmission capacity very convenient without
installing new fibers.
