Perle S-1000MM-S1SC120D - Media converter - GigE - 1000Base-SX, 1000Base-BX-D - SC multi-mode / SC single-mode - up to 74.6 miles - 850 nm / 1590 (TX) / 1510 (RX) nm

VLAN. The media converter is transparent to 802.1Q VLAN tagged packets. Pause (IEEE 802.3x). Pause signaling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed. The media converter is transparent to pause frames. Smart link pass-through. When the link mode switch is placed into smart link pass-through mode, the 1000BASE-X link on one port will reflect the state of the other 1000Base-X media converter port. This feature can be used whether fiber auto-negotiation is enabled or disabled. Signal regeneration. Signal regeneration maintains signal integrity and allows for maximum fiber to fiber connections without degradation. Auto-negotiation (802.3ab). The 1000Base-X fiber interfaces negotiate according to 802.3 clause 37. Cascading. Media converters can be cascaded. Two or more media converters can be chained in a link to achieve even greater distances. Remote loopback. The media converter can perform a loopback on each 1000Base-X fiber interface. Fiber fault alert. With fiber fault alert the state of the 1000Base-X receiver is passed to the 1000Base-X transmitter. This provides fault notification to the partner device attached to the 1000Base-X interface of the media converter. If the 1000Base-X transmitter is off as a result of this fault it will be turned on periodically to allow the condition to clear should the partner device on the 1000Base-X be using a similar technique. This eliminates the possibility of lockouts that occur with some media converters.
