NOTES:
1. THIS FIGURE DESCRIBES THE RECOMMENDED CIRCUIT BOARD LAYOUT FOR THE SFF TRANSCEIVER.
2. THE HATCHED AREAS ARE KEEP-OUT AREAS RESERVED FOR HOUSING STANDOFFS. NO METAL TRACES OR
3. 2 x 10 TRANSCEIVER MODULE REQUIRES 26 PCB HOLES (20 I/O PINS, 2 SOLDER POSTS AND 4 PACKAGE
4. THE MOUNTING STUDS SHOULD BE SOLDERED TO CHASSIS GROUND FOR MECHANICAL INTEGRITY AND TO
5. HOLES FOR HOUSING LEADS MUST BE TIED TO SIGNAL GROUND.
Package footprint and front panel considerations
Avago Technologies’ transceivers comply with the circuit
board “Common Transceiver Footprint” hole pattern de-
fined in the current multisource agreement which defined
the 2 x 10 package style. This drawing is reproduced in
Figure 7 with the addition of ANSI Y14.5M compliant di-
mensioning to be used as a guide in the mechanical layout
of your circuit board. Figure 8 shows the front panel dimen-
sions associated with such a layout.
Eye Safety Circuit
For an optical transmitter device to be eye-safe in the event
of a single fault failure, the transmitter must either maintain
eye-safe operation or be disabled.
The HFCT-5962TL/TG/NL/NG/ATL/ATG is intrinsically eye
safe and does not require shut down circuitry.

Signal Detect
The Signal Detect circuit provides a de-asserted out-
put signal when the optical link is broken (or when the
remote transmitter is OFF). The Signal Detect thresh-
old is set to transition from a high to low state be-
tween the minimum receiver input optical power and
-45 dBm avg. input optical power indicating a definite opti-
cal fault (e.g. unplugged connector for the receiver or trans-
mitter, broken fiber, or failed far-end transmitter or data
source). The Signal Detect does not detect receiver data
error or error-rate. Data errors can be determined by signal
processing offered by upstream PHY ICs.
