What's the function of the Cisco module

What's the function of the Cisco light module ?
Cisco module classification and description:
1 Cisco 1 × 9 package optical modules: welding type module, general speed is less than1000m, using SC interface.
2 SFF package, Cisco optical module: welding small package module, general speed is less than 1000m, using LC interface.
3 GBIC package, Cisco optical module: hot pluggable Gigabit interface module, using SC interface.
4 SFP package, Cisco optical module: hot plug small package module, the highest rate of up to 4G, use the LC interface.
5 XENPAK package, Cisco optical module: applications in Gigabit Ethernet, using the SC interface.

The optical module is connected to the module of a photoelectric conversion effect, which transmit the electric signal into optical signal, the optical fiber transmission, the receiving end ofthe optical signals are converted into electric signals. The optoelectronic devices, circuits andoptical interface and other components, optoelectronic devices including the transmitting and receiving two parts.
Cisco 4500 6500 and 7600 are modular design, apart from the main chassis, supervisor engine,linecard, power supplies and modules will be also required for these products. 3Anetwork.comwholesales Cisco 450065007600 Modules, ship to worldwide.

WS-X6548-GE-TX VS WS-X6748-GE-TX

The difference between WS-X6548-GE-TX & WS-X6748-GE-TX

WS-X6548-GE-TX uses Centralized Bus Forwarding as opposed to CEF720 Bus Forwarding used on WS-X6748-GE-TX.

The CEF720 uses 2x20Gbps connection to the switch fabric, which on this case is the Sup Module (no need for a switch fabric module).

WS-X6548-GE-TX is only 1MB buffer per port while WS-X6748-GE-TX is 1.3MB buffer per port.

WS-X6548-GE-TX is a hybrid, it supports backplane connection in switch fabric or bus mode while WS-X6748-GE-TX can only support switch fabric.

Personally, I see WS-X6748-GE-TX, the module of choice if you have a Sup720 since it uses the ideal Bus Forwarding for this hardware.

WS-X6748-GE-TX: Supervisor Engine 720, 720-10GE and 2T-10GE.

The WS-X6748-GE-TX is not supported in the Catalyst 6503 switch chassis. The WS-X6748-GE-TX module can occupy any slot in any other Catalyst 6500 or Catalyst 6500-E chassis except the Catalyst 6513 chassis where the module must be installed in slots 9-13. The module does not power up when it is installed in slots 1-8.

WS-X6748-GE-TX ships with the WS-F6700-CFC daughter card factory-installed. The module can be upgraded in the field to support the WS-F6700-DFC3A, WS-F6700-DFC3B, WS-F6700-DFC3BXL, WS-F6700-DFC3C, WS-F6700-DFC3CXL, WS-F6K-DFC4-A, or the WS-F6K-DFC4-AXL daughter cards.
