40Gb/s QSFP Transceiver
PRODUCT NUMBER:TQS-Q1LH9-PCA
Purpose
This document validates solely for the product of Formerica OptoElectronics lnc., 40-Gbps
QSFP+ Parallel Optical Enhanced Transceiver Module. However, this document is not fully
complete yet, therefore, this datasheet only provides basic information and electronic
characteristics. This document is for customer’s reference only, and it subjects to change
without notice.
Description
Formerica OptoElectronics lnc. Quad Small Form-factor Pluggable Plus (QSFP+) product is
a new high speed pluggable I/O interface products. This interconnecting system offers 4
channels and maximum bandwidth of 40Gbps which are based on the proprietary technique
Silicon Optical Bench (SiOB) optical engine. Compared to common 40GBASE-SR4
transceiver only can support cable length up to 100-m via OM3 MMF, this product can
extend the cable length up to 300-m via common OM3 MMF by special dispersion
suppression technique. This module provides high performance and extra longer cable
distance for datacom applications.
Features
 Compliant with 40GBASE-SR4 per IEEE 802.3ba D3.2 and SFF-8436 QSFP+ MSA Rev.
4.1.
 Operating at 10.3125-Gbps per lane with 64b/66b coded data
 Low power dissipation < 1.5W (Power Level-1)
 Full Digital Diagnostics Monitor Interface
 Hot pluggable electrical interface
 Standard 12/8 lane optical fiber with MPO pluggable optical connector.
 0 to 70°C case temperature operating range

Note:
1. Lane speed up to 12.5-Gbps is available upon customer requests.
2. Power supply noise is defined as peak-to-peak noise amplitude over 1K to 15 MHz frequency
range at host supply side by the recommended power supply filter for module. See Section 10
for the recommended power supply filter.
3. Extended 300-m /400-m via OM3/OM4 MMF is only supported as long as two ends of QSFP+
transceiver module belonging to Extended SR4; otherwise, the link length might only supports to
100-m/150-m via OM3/OM4 MMF according to 40GBase-SR4.

Notes:
1. “Initialization Time” is the time from when the supply voltages reach and remain above the
minimum “Recommended Operating Conditions” to the time when the module enables TWS
access. The module at that point is fully functional.
2. 10M to 11.1 GHz according to IEEE 802.3ba specification.
3. Hit ratio= 5 × 10-5 per sample.
4. AC-Coupled with 100Ω differential output impedance.

Note:
1. GND is the symbol for signal and supply (power) common for the QSFP+ module. All are common
within the QSFP+ module and all module voltages are referenced to this potential unless otherwise
noted. Connect these directly to the host board signal-common ground plane.
2. Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied
concurrently. Requirements defined for the host side of the Host Edge Card Connector are listed in
Table . Recommended host board power supply filtering is shown in next page. Vcc Rx Vcc1 and
Vcc Tx may be internally connected within the QSFP+ module in any combination. The connector
pins are each rated for a maximum current of 500 mA.
