Product Description
The ES1052-LPTTA from E2O Communications is a
hot pluggable duplex-LC transceiver designed for use in
10Gigabit Ethernet applications. The transceiver is
compatible with the industry standard XFP connector and
cage and conforms to the 10Gbps Small Form-factor
Pluggable (XFP) multi-source agreement (MSA).
The transceiver consists of optical subassemblies for
both the transmitter and the receiver, and an electrical
subassembly. All are packaged together with a top metal
cover and bottom shield.
The optical subassembly consists of 2 parts. The
transmitter side has a high-performance 1310-nm DFB
laser and back facet monitor. The receiver side has a high
speed InGaAs PIN type detector and a preamplifier.
All ES1052-LPTTA transceivers also include state-of-
the-art circuitry designed to restore signal quality of the
high speed 10Gbps serial data inputs and outputs. This
circuitry ensures that the serial data can be transmitted
over as much as 200mm (8”) of FR-4 printed circuit
board from the host with no adverse effects. With
enhanced FR-4 (NELCO) this can be increased to 300mm
(12”).
A serial EEPROM in the transceiver allows the user to
access transceiver monitoring and configuration data via
the 2-wire XFP Management Interface. The user can
monitor transceiver parameters including module
temperature, power supply voltage, laser bias current,
laser power and received optical power. Alarms and
Warnings are provided when the monitored parameters
exceed pre-defined threshold values which are held in
lower memory. Details of the Serial Identification
Protocol is contained in the XFP Multi-Source
Agreement.
Electromagnetic Interference (EMI) & Immunity
The ES1052-LPTTA transceivers, with their shielded
design, have reduced emissions to assist the designer in
the management of the overall equipment EMI
performance.
The ES1052-LPTTA transceiver has been designed to
provide good immunity to radio-frequency
electromagnetic fields. Key components to achieve the
good electromagnetic performance (EMC) are the internal
and bottom shields, the metal cover, and the XFP cage
which includes an EMI gasket on the front.
Eye Safety
The ES1052-LPTTA 1300-nm laser-based transceivers
have been designed to meet Class 1 eye safety. They
conform to FDA 21CFR1040.10 and 1040.11 and IEC
60825-1.
