Product Descriptions
GFC-OLSBxx1XL-CDH1 series single mode transceiver is small form factor pluggable module for optical data communications such as 10G Ethernet. It is with the SFP+ 20-pin connector to allow hot plug capability. The OLSBxx1XL-CDH1 module is designed for single mode fiber and operates at a nominal wavelength of 1530nm or 1550nm; The transmitter section uses a EML laser, which is class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section consists of a APD photodiode integrated with a TIA. The transceiver designs are optimized for high perform -ance and cost effective to supply customers the best solutions for   telecommunication.

General Operating Characteristics

Notes:

1. Connected   directly   to   TX   data   input   pins.   AC   coupling   from   pins   into   laser   driver   IC.
2. Into 100 differential   termination.
3. 20   -   80%.   Measured   with   Module   Compliance   Test   Board   and   OMA   test   pattern.   Use   of   four  1's   and   four   0's   sequence   in   the   PRBS   9   is   an acceptable   alternative.
4. LOS   is   an   open   collector   output.   Should   be   pulled   up   with   4.7k   -   10k   on   the   host   board.   Normal   operation   is   logic   0;   loss   of   signal   is   logic   1.

Notes:

 

1. Module   circuit   ground   is   isolated   from   module   chassis   ground   within   the   module.
2. should   be   pulled   up   with   4.7k   -   10k   ohms   on   host   board   to   a   voltage   between   3.15Vand   3.6V. 3.Tx_Disable   is   an   input   contact   with   a   4.7   kΩ   to   10   kΩ   pullup   to   VccT   inside   the   module.

4.Mod_ABS   is   connected   to   VeeT   or   VeeR   in   the   SFP+   module.   The   host   may   pull   this   contact   up   to   Vcc_Host   with   a   resistor   in   the   range   4.7   kΩ   to10 kΩ.Mod_ABS   is   asserted   "High" when   the   SFP+   module   is   physically   absent   from   a   host   slot.
 

Serial Interface for ID and Digital Diagnostic Monitor

 

The OLSBxx1XL-CDH1 transceiver support the 2-wire serial communication protocol as defined in the SFP+  MSA.  The standard SFP+ serial ID provides access to identification information that describes the transceiver's capabilities, standard interfaces, manufacturer, and other information. Additionally, This SFP+ transceivers provide an 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 EEPROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X(A0h), so the originally monitoring interface makes use of the 8 bit address(A2h), so the originally defined serial ID memory map remains unchanged. The structure of the memory map is shown in Table1.


The OLSBxx1XL-CDH1 transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics.
