PRODUCT DESCRIPTION

The transceiver is hot pluggable 3.3V Small-Form-Factor transceiver module. It designed expressly for high-speed communication applications that require rates up to 10.7Gb/s, it designed to be compliant with XFP MSA. The module data link up to 60km in 9/125um single mode fiber.

The optical output can be disabled by a LVTTL logic high-level input of Tx Disable. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner.

Notes:

Module circuit ground is isolated from module chassis ground within the module.
Open collector; should be pulled up with 4.7k – 10kohms on host board to a voltage between 3.15V and 3.6V.
A Reference Clock input is not required by the XFP-10GER. If present, it will be ignored.
