Hi,

C2851 can only support 1 fibre optic cables with LX connectors. You need the following;

1 x HWIC-1GE-SFP (C2851 supports only one)

1 x GLC-LH-SM=

Re: 2851 Router

Hi,

It's not mentioned in the data sheet but you don't get 1Gbps from this (or any other) HWIC because the bus is only 400Mbps.

Here's a quote from the Q&A:

Q. What is the maximum throughput on the Gigabit Ethernet HWIC?

A. The HWIC bus interface is limited to 400 Mbps of full duplex. The actual throughput of the Gigabit Ethernet HWIC is limited by the throughput of individual platforms. Under bidirectional traffic of 1518 bytes or larger, the Gigabit Ethernet HWIC can support up to an aggregate of 350 Mbps on Cisco 2811 and 2821 routers, 400 Mbps on Cisco 2851 routers, and 500 Mbps on Cisco 3800 Series platforms.

Andrew.
