LASER SAFETY
This single-mode transceiver is a Class 1 laser product. It
complies with IEC-60825 and FDA 21 CFR 1040.10 and
1040.11. The transceiver must be operated within the
specified temperature and voltage limits. The optical ports
of the module shall be terminated with an optical connector
or with a dust plug.
XPS-2140WG series transceivers are designed for
single-mode fibre serial optical data communications such as
10G Ethernet 10GBASE-ER/EW and 10G Fibre Channel
1200-SM-LL-L.
The transceiver consists of two sections: The transmitter
section consists of a directly modulated uncooled 1310 nm
DFB laser, driver and signal conditioner. The receiver
section incorporates a PIN photodiode integrated with a
trans-impedance preamplifier (TIA) and signal conditioner.
The module is with the XFP 30-pin connector to allow
hot plug capability. Integrated Tx and Rx signal conditioners
provide high jitter-tolerance for full XFI compliance and no
external reference clock required. The internally ac coupled
high speed serial I/O simplifies interfacing to external
circuitry. Only single 3.3V power supply is needed. The
optical output can be disabled by LVTTL logic high-level
input of TX_DIS. Loss of signal (RX_LOS) output is
provided to indicate the loss of an input optical signal of
receiver.
A serial EEPROM in the transceiver allows the user to
access transceiver digital diagnostic monitoring and
configuration data via the 2-wire XFP Management
Interface. This interface uses a single address, A0h, with a
memory map divided into a lower and upper area. Basic
digital diagnostic data is held in the lower area while specific
data is held in a series of tables in the high memory area.

Management Interface
The structure of the memory map is shown in Figure 1, which is accessible over a 2-wire serial interface at the 8-bit
address 1010000X (A0h). The normal 256 byte I2C address space is divided into low and upper blocks of 128 Bytes. The
lower block of 128 Bytes is always directly available and is used for the diagnostics and control function. Multiple blocks of
memories are available in the upper 128 Bytes of the address space. These are individually addressed through a table select
Byte which the user enters into a location in the lower address space. Thus, there is a total available address space of 128*256
= 32 Kbytes in this upper memory space. The contents of Table 01h are listed in Table 1 below. Please refer SFF INF-8077i
(Revision 4.5) for detailed information.
