SFP 1.25G 10KM 1310&1550 optical transceivers are designed for optical interfaces for data communications with single mode

 

fiber (SMF).The transceiver designs are optimized for high performance and cost effective to supply customers the best

 

solutions for telecom applications.

 

 

 

 

SFP 1.25G 10KM 1310&1550 transceivers support the 2-wire serial communication protocol as defined in the SFP MSA. It is

 

very closely related to the E2PROM 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, SFP 1.25G 10KM 1310&1550 transceivers provide a unique 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 E2PROM that is accessible over a 2-wire serial interface at the 8bit 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 E2PROM 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.

 

Digital diagnostics for the TOP-BIDI-1.25G-10AD/BD are Internally calibrated by default.
