1. General
This document specifies the characteristics of the Small Form Factor Pluggable optical
transceiver (Type:HTR6516) with LC duplex receptacle for 1.25Gbit/s Gigabit Ethernet and
1.0625Gbit/s Fibre Channel. Maximum transmission distance is 10km at the data rate of
1.25Gbit/s and 1.0625Gbit/s. This transceiver apply single mode optical fiber - 9/125.
2. Function
This transceiver is powered from a single +3.3V power supply and operated at a data rate of
1.25Gbit/s or 1.0625Gbit/s(NRZ). Optical output power is held constant by automatic power
control over the specified operating temperature and voltage ranges.
The optical output is disabled by a TTL logic level input for that purpose. Tx Fault is provided
to indicate the degradation of the laser diode. Loss Of Signal (LOS) output is provided to indicate
the loss of an incoming optical signal. Tx Fault and LOS are open collector type outputs. The type
of this transceiver is identified by Module Definition function using a built-in EEPROM with I
2
C
interface.
As enhanced functions for SFP, internally measured transceiver temperature, internally
measured supply voltage, laser bias current, laser optical output power and received optical power
can be monitored by reading a built-in memory with I
2
C interface for that purpose. The interface
pins for the monitor function are common with the Module Definition function.
Dimensions and pin assignment fully comply with MSA (Multi Source Agreement) for SFP
(Small Form Factor Pluggable) optical transceiver.

5. Optical and Electrical Characteristics of Transmitter Portion
Optical and electrical characteristics of transmitter portion are shown in Table 2. Unless
otherwise stated, minimum and maximum values are specified over the operating ambient
temperature, and humidity ranges, DC power supply voltage range, from beginning to end of life,
using 2
7
-1 pseudo random bit stream with a 50% duty factor.
The logic sense for the DATA input is such that a logic "1"(High) corresponds to the maximum
level of an amplitude modulated light source (Light on), while a logic "0"(Low) corresponds to a
minimum level of an amplitude modulated light source (Light off).

The measured values located at bytes 96-105 (in the 2 wire address 0xA2) are raw A/D values (16-bit
integers) of transceiver temperature, supply voltage, laser bias current, laser optical output power and
received power. All the measured values are "externally calibrated" over specified temperature and
supply voltage, and then it is necessary to convert raw A/D values to real world units using the
external calibration constants located at bytes 56-91 (0xA2) by the manner as shown in Table 6.2.

This transceiver is implemented two optional status bits, "Logic States" at byte 110 (0xA2) and "A/D
Updated" at byte 111 (0xA2) as shown in Table 6.4. "A/D updated" status bits allows the user to
verify if an update from the analog -digital conversion has occurred to the measured values,
temperature, Vcc, laser bias, Tx power and Rx power. The user writes the byte to 0x00. Once a
conversion is complete for a given value, its bit will change to '1'.

Each of the measured values has a corresponding high alarm, low alarm, high warning and low
warning threshold level at location 00-39 (0xA2) written as the data format of a corresponding value
shown in Table 6.2. Alarm and warning flags at bytes 112-119 (0xA2) are defined as follows,
(1) Alarm flags indicate conditions likely to result (or have resulted) in link failure and cause for
immediate action,
(2) Warning flags indicate conditions outside the guaranteed operating specification of transceiver but
not necessarily causes of immediate link failures.

13. Inspection
Inspection items are as follows:
(1) Appearance
(2) Dimensions
(3) Optical output power
(4) Optical waveform
(5) Optical input power
a) Average sensitivity
b) Loss of Signal / Decreasing light input
c) Loss of Signal / Increasing light input
(6) Power supply current
14. Packing
The optical transceiver shall be packed in sturdy carton box(es) when shipping.
15. Caution
(1) Do not stare into optical output port although this product is designed to meet the class 1
laser regulation.
(2) The housing of the transceiver is possible to crack or dissolve against the particular
chemicals. Although we recommend to use the aqueous fluid in the cleaning, the below
chemicals are checked not to affect to the housing. Pay attention in the solder flux and
cleaning process. We recommend checking the appropriateness of the cleaning fluid in
advance.
/ methyl alcohol, ethyl alcohol, butyl alcohol, isopropyl alcohol, hexane, cyclohexane,
naphtha, tetrachloroethylene, propylene glycol
< Do not use : Chemicals which are checked to crack or dissolve>
/ trichloroethylene, trichloroethane, benzen, methyl ethyl ketone, chloroform, toluene,
acetone, phenol, ethyl acetate,
methylene di chloride
(3) Optical connectors should be cleaned completely by proper cleaning process before insertion to
optical receptacles of the transceiver to avoid contamination inside the optical receptacle.
The contamination may cause serious degradation of transmission performance. Using
forced nitrogen and some kind of cleaning stick ("CLETOP, stick type" for LC/MU connector
supplied by NTT international is recommended) should be used if the receptacle get
contaminated by miss-treating optical connectors.
