How to connect Cisco 3750 with fiber?

What SFP module would you use to connect a 3750 switch WS-C3750X-48P-L to a 3550 that is using a WS-G5486 Gigabit module? Does anyone have experience with SX to LX adapters and if they are reliable?

The answer:
You would need to use a GLC-LH-SMD transceiver for this, and a LC-SC single-mode patch cord (if they're being connected directly without an intermediate patch-panel).
They are very reliable and are used for long links, well over the length that SX modules can go.

Catalyst 3750 is next-generation energy-efficient Layer 3 Fast Ethernet stackable switches while 3750X is layer 3 GE switches. The Cisco Catalyst 3750 v2 Series consumes less power than its predecessors 3750.
