SFP28 25G SFP Fiber Optic Transceiver 850nm VCSEL Transmitter For Inter Rack Connectione

Description:

SH's SH001D is a very compact optical transceiver module converts 25Gbit/s serial PECL or CML electrical data into serial optical data compliant with the 25GBASE-SR standard. The SFP28 SR module electrical interface is compliant to SFI electrical specifications. The VCSEL transmitter and PIN receiver provide superior performance for Ethernet applications at up to 100m links on OM4 MMF.

The SFP+ Module compliant with SFF-8431, SFF-8432 and IEEE 802.3ae 25GBASE-LR. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472.

The fully SFP compliant form factor provides hot pluggability, easy optical port upgrades and low EMI emission.

l Absolute Maximum Ratings

l Electrical Characteristics (T_OP = 0 to 70 °C, VCC = 3.135 to 3.465 Volts)

Note:

1. Connected directly to TX data input pins. AC coupling from pins into laser driver IC.

2. Per SFF-8431 Rev 3.0

3. Into 100 ohms differential termination.

4. 20%～80%

5. LOS is an open collector output. Should be pulled up with 4.7k – 10kΩ on the host board. Normal operation is logic 0; loss of signal is logic 1. Maximum pull-up voltage is 5.5V.

l Optical Characteristics (TOP = 0 to 70°C, VCC = 3.135 to 3.465 Volts)

Note:

1. Average power figures are informative only, per IEEE802.3ae.

2. TWDP figure requires the host board to be SFF-8431compliant. TWDP is calculated using the Matlab code provided in clause 68.6.6.2 of IEEE802.3ae.

3. 12dB reflection.

4. Conditions of stressed receiver tests per IEEE802.3ae. CSRS testing requires the host board to be SFF-8431 compliant.

5. Receiver overload specified in OMA and under the worst comprehensive stressed condition.

• SFP Module EEPROM Information and Management

The SFP modules implement the 2-wire serial communication protocol as defined in the SFP -8472. The serial ID information of the SFP modules and Digital Diagnostic Monitor parameters can be accessed through the I²C interface at address A0h and A2h.

The memory is mapped in Table 1.

Detailed ID information (A0h) is listed in Table 2.

And the DDM specification at address A2h.

For more details of the memory map and byte definitions, please refer to the SFF-8472, “Digital Diagnostic Monitoring Interface for Optical Transceivers”. The DDM parameters have been internally calibrated.
