It is designed for support data rates from 9.95Gbps to 10.5Gbs and transmission distance to 10 km on 9/125 μm SMF The transceiver consists of two sections: The transmitter section incorporates an uncooled CWDM DFB laser, driver, The receiver section consists of a PIN photodiode integrated with a transimpedance preamplifier (TIA) and CDR. A block diagram of the HXFP-2C21XX XFP optical transceiver is shown below Page 1 of 9
The module is hot pluggable into the 30-pin XFI connector. The high-speed electrical interface is base on low voltage logic, with nominal 100 Ohms differential impedance and AC coupled in the module. The optical output can be disabled by LVTTL logic high-level input of TX_DIS. Loss of signal (RX_LOS) output is provided to indicate the loss of an input optical signal of receiver. The user can access transceiver monitoring and configuration data via the 2-wire XFP Management Interface. This interface uses a single address, A0h, with a memory map divided into a lower and upper area. Basic digital diagnostic (DD) data is held in the lower area while specific data is held in a series of tables in the high memory area. Absolute Maximum Ratings Parameter Symbol Min. Max.

Digital Diagnostic Memory Map The structure of the memory map is shown in Figure 1, which is accessible over a 2 wire erial interface at the 8-bit address 1010000X (A0h). The normal 256 Byte I2C address space is divided into lower and upper blocks of 128 Bytes. The lower block of 128 Bytes is always directly available and is used for the diagnostics and control function. The monitoring specification is shown in Table 6. Multiple blocks of Page 4 of 9
memories are available in the upper 128 Bytes of the address space. These are individually addressed through a table select Byte which the user enters into a location in the lower address space. Thus, there is a total available address space of 128 * 256 = 32Kbytes in this upper memory space. The contents of Table 01h are list in table 7 below.
