MRV’s SFP-10GD-LR 10 Gbps Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-Gigabit Ethernet
and 10 Gigabit Fibre Channel links up to 10km over single-mode fiber. They are compliant with SFF-8431, SFF-8432 and IEEE 802.3ae
10GBASE-LR/LW. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The
SFP-10GD-LR
is
a “limiting module”, i.e., it employs a limiting receiver. Host board designers using an EDC PHY IC should follow the IC manufacturer’s
recommended settings for interoperating the host-board EDC PHY with a limiting receiver SFP+ module. The transceiver is RoHS
compliant and lead free per Directive 2002/95/EC.

is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on the host board if
intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates a transmitter fault caused
by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal

Digital Diagnostics Functions
MRV’s SFP-10GD-LR SFP+ transceivers support the 2-wire serial communication protocol as defined in the SFF-8472. It is very closely
related to the E
2
PROM defined in the GBIC standard, with the same electrical specifications.
The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces,
manufacturer, and other information.
Additionally, MRV’s SFP+ transceivers provide a enhanced digital diagnostic monitoring interface, which allows real-time access to
device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power
and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end-users when
particular operating parameters are outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in E
2
PROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X
(A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial ID
memory map remains unchanged. The interface is identical to, and is thus fully backward compatible with both the GBIC Specification
and the SFP Multi Source Agreement.
The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside
the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is activated, the serial clock signal (SCL,
Mod Def 1) is generated by the host. The positive edge clocks data into the SFP transceiver into those segments of the E
2
PROM
that are not write-protected. The negative edge clocks data from the SFP transceiver. The serial data signal (SDA, Mod Def 2) is bi-
directional for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation.
The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially.
For more information, please see the SFP MSA documentation.
SFP-10GD-LR transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics.
