Optoway XPB-2820LWG 1 *********************************************************************************************************************************************************************** XPB-2820LWG / XPB-2820BLWG / XPB-2820BLWG (RoHS Compliant) 1270 nm TX / 1330 nm RX , 10.3 Gbps 1-Fiber Single-Mode LC XFP Transceiver ********************************************************************************************************************************************************************** FEATURES DESCRIPTION l l l l l l l l l l XPB-2820LWG series transceiver is designed for bi-directional serial optical data communications such as IEEE 802.3ae 10GBASE-BX by using 1270 nm transmitter and 1330 nm receiver. The transceiver consists of two sections: The transmitter section uses a multiple quantum well 1270 nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated 1330 nm detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. The module is with the XFP 30-pin connector to allow hot plug capability. Integrated Tx and Rx signal conditioners provide high jitter-tolerance for full XFI compliance and no external reference clock required. The internally ac coupled high speed serial I/O simplifies interfacing to external circuitry. Only single 3.3V power supply is needed. 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. A serial EEPROM in the transceiver allows the user to access transceiver digital diagnostic 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 data is held in the lower area while specific data is held in a series of tables in the high memory area. l l l l l l l l l 1-Fiber Bi-Directional XFP Optical Transceiver Up to 10.3 Gbps Bi-directional Data Links Compliant with XFP MSA Compliant to IEEE 802.3ae 10GBASE-BX SFF-8472 Digital Diagnostic Function Simplex LC Connector 1270 nm DFB LD Transmitter 1330 nm Receiver Distance Up to 20 km 2-Wire Interface for Integrated Digital Diagnostic Monitoring XFI Loopback Mode No reference Clock required Only Required +3.3 V Power Supply Power Consumption < 2 W RoHS Compliant 0 to 70oC Operating : XPB-2820LWG -10 to 85oC Operating : XPB-2820BLWG -40 to 85oC Operating : XPB-2820ALWG Simplex LC Connector APPLICATIONS l 10GBASE-BX at 10.3125 Gb/s l 10GBASE-BX at 9.953 Gb/s LASER SAFETY This single-mode transceiver is a Class 1 laser product.

The normal 256 byte I2C address space is divided into low 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. Multiple blocks of 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 = 32 Kbytes in this upper memory space. The contents of Table 01h are listed in Table 1 below.
