Ports 1 to 24 on the AT-x950-28XSQ Switch
Ports 1 to 24 on the AT-x950-28XSQ Switch support 1Gbps SFP and
10Gbps SFP+ transceivers.
SFP and SFP+
Transceivers Listed here are examples of 1Gbps SFP transceivers:
AT-SPSX and LR short and long distance transceivers using multi-
mode or single mode fiber optic cable.
AT-SPTX transceiver series with RJ-45 connector for twisted pair
cable.
AT-SPEX transceivers with a maximum distance of two kilometers
with multi-mode fiber optic cable.
Listed here are examples of SFP+ 10Gbps transceivers:
AT-SP10SR, LR, ER and ZR series of short or long distance
transceivers using multi-mode or single mode fiber optic cable.
AT-SP10TW series of direct attach cables in lengths up to seven
meters.
AT-SP10BD series of bidirectional transceivers for single mode
fiber optic cable with maximum distances of 10 to 40 kilometers
AT-SP10T transceiver with RJ-45 connector for links up to 20
meters at 10Gbps with Category 6a twisted pair cable, or 100
meters at 1Gbps.
AT-SP10LRM Long Reach Multimode transceiver for OM1 multi-
mode fiber optic links up to 220 meters.
Note
Industrial (-40 to 85° C) and extended (-40 to 105° C) temperature
transceivers are available.
Here are transceiver guidelines:
The ports do not support 100Mbps-FX transceivers.
They support full-duplex mode only.
You can set the port speeds with Auto-Negotiation or manually.
The default is Auto-Negotiation.
Transceivers must be purchased separately. For a list of supported
transceivers, refer to the product data sheet on the Allied Telesis web site.
