Product Descriptions

25G-SR SFP28 850nm 100m optical transceiver is designed for use in 25Gb/s data rateover Multi-mode fiber for link length 100m.

Each SFP28 transceiver module is individually tested on a series of Dell switches, and is fully compliant with the SFP28 MSA, RoHS, CPRI, and the eCPRI standards.

The transceiver designs are optimized for high perform-ance and cost effective to supply customers the best solutions for 25Gb/s single lane optical links.

1. TD+/- are internally AC coupled with 100Ω differential termination inside the module.

2. Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kΩ resistors on the host board. Pull up voltage between 2.0V and Vcc+0.3V.

3. RD+/- outputs are internally AC coupled, and should be terminated with 100Ω (differential) at the user SERDES.
