Optical Specifications and Connectors

Refer to OSD860 SFP datasheet #102860SFP04

Notes: Many combinations of laser types and levels and receiver types and sensitivities are possible. Contact OSD for details. The OSD860S reverse path is not compatible with the OSD860 reverse path. The OSD860S is easily distinguishable because it employs one or two removeable SFP optical modules whereas the OSD860 has fixed optical connector(s)

*It is possible to configure the unit as 8 audio+0 HS data, 4 audio+4 HS data or 0 audio+8 HS data.
