3.3V / 5V GBIC Transceiver for Dual Rate Fibre Channel
850 nm VCSEL for Multimode Fiber
E2O Communications, Inc.
EM212-GDTA
Data Sheet
The transmitter consists of a high-performance 850-nm
VCSEL while the receiver consists of a GaAs PIN and
a preamplifier. At the same time, a serial EEPROM in the
transceiver allows the user to access information such as
the GBIC’s capabilities, the standard interfaces as well as
the manufacturer. Details of the Serial Identification
Protocol are contained in Annex D of the GBIC MultiSource Agreement (MSA) specification.
All EM212-GDTA transceivers also include a Loss-OfSignal-Detect circuit which provides a TTL logic high
output when an unusable input optical signal level is
detected.

Product Description
The EM212-GDTA from E2O Communications is a +3.3V
or +5V, duplex-SC transceiver designed for use in Dual
Rate Fibre Channel applications. The transceiver conforms
to the Gigabit Interface Converter (GBIC) specification
and meets the mezzanine height requirement of 9.8 mm.
Each EM212-GDTA transceiver consists of a transmitter
optical subassembly, a receiver optical subassembly, and
an electrical subassembly. All are packaged inside a
metallized plastic frame with metal cover.
Electromagnetic Interference (EMI)
Most equipment utilizing high-speed transceivers will be
required to meet the following requirements:
1) FCC in the United States
2) CENELEC EN55022 (CISPR 22) in Europe. and
3) VCCI in Japan.
To assist the customer in managing the overall equipment
EMI performance, the EM212-GDTA transceivers have
been designed to perform to the specified limits. All
transceivers comply with the FCC Class B limits.
Immunity
The EM212-GDTA transceiver has been designed to
provide
good
immunity
to
radio-frequency
electromagnetic fields. Key components to achieve the
good electromagnetic compliance (EMC) are the
metallized plastic frame, the metal cover, and the chassis
shield.
Eye Safety
The EM212-GDTA 850-nm VCSEL-based transceivers
have been designed to meet Class 1 eye safety and comply
with FDA 21CFR 1040.10 and 1040.11 and the IEC 8251.
