Section 1
This transceiver is a fully duplex serial electric, serial optical device with both
transmit and receive functions contained in a single module that provides a high-
speed serial link at signaling rates from 9.95 to 11.35 Gbps. The 80 km reach module
complies with ITU-T G.698.1 S-D100S1-2D (SONET/SDH), 10GBase-ZR/ZW
(Ethernet) and 10GFC (Fibre Channel). The 40 km reach module complies with
Telcordia GR-253-CORE OC-192 IR-2 (SONET), ITU-T G.691 STM-64 S-64.2b
(SDH), IEEE 802.3-2008 Clause 52 10GBase-ER (Ethernet), and 10GFC (Fibre
Channel). The transceiver is also fully compliant with the 10 Gigabit Small Form
Factor XFP Pluggable Module Multi-Source Agreement INF8077i Rev. 4.5. A block
diagram of the transceiver is shown in Figure 1 below.
The transceiver locks to data without the requirement of a reference clock. The
reference clock inputs have an internal AC-coupled 100 Ω differential line-to-line
termination. It has several low-speed interface connections including a two-wire
serial interface. These connections include: module not ready (Mod_NR), module
deselect (Mod_DeSel), interrupt, transmitter disable (TX_DIS), module absent
(Mod_ABS), receive loss (RX_LOS), and power down/reset (P_Down/RST).
The transceiver supports XFI system loopback. In this mode, data input on the
electrical Tx pins of the XFP module is retimed and is re-directed to the Rx pins of
the module. This facilitates system-side test and debug. The transceiver also supports
line loopback. In this mode, data input on the optical Rx port of the XFP module is
retimed and is re-directed to the optical Tx port of the module. This facilitates line-
side test and debug.
Transmitter
The transmitter path converts serial NRZ electrical data from line rates of 9.95 to
11.35 Gbps to a standard compliant optical signal. The transmitter accepts a 100 Ω
differential 120 mV peak-to-peak to 820 mV peak-to-peak 10 Gbps CML electrical
signal on TD– and TD+ pins.
Inside the module, differential signals pass through a signal conditioner with
equalization that compensates for losses and deterministic jitter present on the input
data stream. The transmit CDR function generates a clock that is at the same frequency
as the incoming data bit rate of the electrical data input. The clock is phase aligned by
a phase locked loop (PLL) that samples the data in the center of the data eye pattern.
The CDR function does not require a reference clock to lock to incoming data. The
CDR contains a lock-detect circuit that indicates successful locking of the PLL onto
the incoming data.
The output of the Tx signal conditioner is input to the laser driver which transforms
the small-swing digital voltage to an output modulation that drives a cooled electro-
absorption (EA) modulator. The optical signal meets SONET/SDH, 10 Gigabit
Ethernet, 10 G Fibre Channel, and corresponding Forward Error Correction (FEC)
rates DWDM specifications at ITU grids with 100 GHz channel spacing. Closed-loop
control of the transmitted laser power, modulation swing, and center wavelength over
temperature and voltage variations is provided. The laser is coupled to single-mode
optical fiber through an industry-standard LC optical connector.
