Hi,
I want to interconnect ws-c2960-24TC-L +2SFP with 1000Base-LH GLC-LH-SMD or GLC-LH-SM to ws-c3750G-12S +12SFP ports .
which model of GLC-LH-SMD or GLC-LH-SM want to select ?
I am going to use fiber cable single mode 1310nm 9/125. Do I need Single Mode Duplex SMD(2 fiber count) or SM (Single Fiber)??
I want to know ws-c3750G-12S +12SFP ports that 12SFP port are SM or SMD use LC connector
cheers

The price between the 2 is usually the same but GLC-LH-SMD supports additional option of DOM (Digital Optical Monitoring). So I use GLC-LH-SMD.

Just use SM.

You can use either one. They both work.

hi Reza,
So I use GLC-LH-SMD module in ws-c2960-24TC-L,
if I use SMD how can I use SM(Single Fiber) cable ,that is one way direction , I think I should use Single Mode Duplex(2 Fiber count)
can I connect Single Mode Duplex(2 Fiber count) fiber cable to ws-c3750G-12S???

1)if I use SMD how can I use SM(Single Fiber) cable ,that is one way direction , I think I should use Single Mode Duplex(2 Fiber count)
Ans:-
Both the GLC-LH-SM and GLC-LH-SMD transceivers support the IEEE 802.3 1000BASE-LX/LH standard and so are compatible with each other. The difference between the two is that the GLC-LH-SMD transceiver has additional support for Digital Optical Monitoring capability.
2)
can I connect Single Mode Duplex(2 Fiber count) fiber cable to ws-c3750G-12S???

Correct, use the SMD optics
if I use SMD how can I use SM(Single Fiber) cable ,that is one way direction , I think I should use Single Mode Duplex(2 Fiber count)
When I say single mode that refers to the type of fiber not the number of strands you need. You still need 2 strands (one pair) of fiber.
can I connect Single Mode Duplex(2 Fiber count) fiber cable to ws-c3750G-12S???
Yes, you need two strands (one pair).
