PRODUCT DESCRIPTION
The transceivers are compatible with SFP Multi-Source Agreement
(MSA) and SFF-8472. For further information, please refer to SFP
MSA.
The transmitter section uses a multiple quantum well laser and is a
class 1 laser compliant according to International Safety Standard
IEC-60825. The receiver section uses an integrated InGaAs detector
preamplifier (IDP) mounted in an optical header and a limiting
post-amplifier IC.
155Mbps SFP BIDI Optical Transceiver Module Small Form Factor Pluggable (SFP) transceivers are compatible with
the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The
transceiver consists of five sections: the LD driver, the limiting
amplifier, the digital diagnostic monitor, the FP laser and the PIN
photo-detector .The module data link up to 20KM in 9/125um single
mode fiber.
The SFP-BIDI transceivers are high performance, cost effective
modules supporting dual data-rate of 155Mbps and 20km transmission
distance with SMF.
The transceiver consists of three sections: a FP laser transmitter,
a PIN photodiode integrated with a trans-impedance preamplifier
(TIA) and MCU control unit. All modules satisfy class I laser
safety requirements.
