Description
Samsung's
TR117FA
of small form factor pluggable transceiver are uncooled
transceiver modules operated over the temperature range of -40
°
C to 85
°
C. These
transceiver modules are designed for single mode fiber and operate at a nominal
wavelength of 1300nm. They are incorporated with a high performance optical
subassembly (OSA), a reliable circuit board (PCB) and a low cost plastic package.
The transmitter section of
TR137FA-0D40S
is 1.3
μ
m InGaAsP MQW Fabry Perot (FP)
laser diode. The receiver section uses a highly sensitive InGaAs PIN photodiode.
Transceiver also conforms to the industry SFP Multi-source agreement (MSA). For
the good EMI performance, this transceiver uses the metal cover.
This module will meet the growing demand on the optical network unit (ONU) for
access network and local area network (LAN) for SONET OC-3 and SDH STM-1.
