Notes:

1.

Assumes no mechanical load force on the unit. Ensuring no mechanical load force requires a cable

bend radius of >105 mm within 100 mm of either cable and SFP+ end and >60 mm on the rest of the

cable. Otherwise, the storage temperature range is -20 to 75°C.

Non-condensing.

Notes:

1.

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

2.

Into 100

Ω differential termination.

3.

20 – 80% . Measured with Module Compliance Test Board and OMA test pattern. Use of four 1’s

and four 0’s in sequence in the PRBS^9 is an acceptable alternative. SFF-8431 Rev 4.1

4.

LOS is an open collector output. Should be pulled up with 4.7k

Ω – 10kΩ on the host board.

Normal operation is logic 0; loss of signal is logic 1. Maximum pull-up voltage is 5.5V.

5.

Testing methodology per SFF-8431. Rev 4.1

6.

The FCBG110SD1Cxx is SFI Limiting. 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.
