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.

Product Descriptions


Olinkcom’s OLSP8525L-CDS3 is a high-performance small form factor pluggable SFP module for 2.5Gb/s serial optical data communications such as SDH STM-16 I-16/SONET OC-48 SR-1/2x Fibre Channel application. This SFP transceiver module provides 300m transmission distance over multimode fiber at a nominal wavelength of 850nm. The transmitter section incorporates an 850nm VCSEL laser that is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses a high-speed InGaAs PIN photodiode (PD) and trans-impedance preamplifier. The 2.5Gb/s SFP module series is fully compliant with SFP Multi-Sourcing Agreement (MSA) and SFF-8472.
