SPBD-1250A4Q1RT
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 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 1310nm un-cool FP 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.
Application
z IEEE 802.3ah 1000BASE-BX10
z Gigabit Ethernet Application
z FTTx WDM Broadband Access
z Switch to switch/backbone interface
Performance
z SPBD-1250A4Q1RT data link up to 10km in
9/125um single mode fiber.
z Support industrial temperature operating
