Description: Perle SMI-1000-S2ST120 - Fiber media converter - GigE - 1000Base-T, 1000Base-EZX - RJ-45 / ST single-mode - up to 120 km - 1550 nm
Mfr Part #: 05070134
Perle's advanced line of managed Gigabit media converters, provides transparent and reliable Gigabit Ethernet to fiber connections. While providing an economical means of extending your existing copper based network connection, these media converters are SNMP manageable to enable complete control and status viewing of your fiber links.
Perle Gigabit managed media converters come standard with extensive cost and time saving features.
- 1000Base-T to 1000Base-X Fiber media converters
- Extend network distances up to 160km
- Manage via SNMP, CLI -Telnet/SSH and internet browser
- Advanced media converter features - Smart link pass-through,
- Fiber fault alert, auto-MDIX and loopback
- Auto-negotiation (802.3ab)
The media converter supports auto negotiation. The 1000Base-X fiber interface negotiates according to 802.3 clause 37. The 1000Base-T negotiates according to 802.3 clause 28 and 40. The 1000Base-X will link up with its partner after the highest common denominator (HCD) is reached and the copper has linked up with its partner. The 1000Base-X will continue to cycle through negotiation transmitting a remote fault of offline (provided this is enabled through the switch setting) until the copper is linked up and the HCDs match. The media converter supports auto-negotiation of full duplex, half duplex, remote fault, full duplex pause, asymmetric pause and auto MDI-X.
- Auto-MDIX with skew correction
Auto-MDIX (automatic medium-dependant interface crossover) detects the signaling on the 1000Base-T interface to determine the type of cable connected (straight-through or crossover) and automatically configures the connection when enabled. The media converter can also correct for wires swapped within a pair. The media converter will adjust for up to 64ns of delay skew between the 1000Base-T pairs.
- Smart link pass-through
When the Link Mode switch is placed into Smart link pass-through mode, the 1000BASE TX port will reflect the state of the 1000Base-X media converter port. This feature can be used whether fiber auto-negotiation is enabled or disabled.
- 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. Applies only when fiber auto-negotiation is disabled.
- 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 supports pause negotiation on the 1000Base-T fiber connection and 1000Base-X fiber connection. Select Symmetrical, asymmetrical TX or asymmetrical RX
Transparent to VLAN tagged packets.
- Remote loopback
Capable of performing a loopback on the 1000Base-X fiber interface.
