● General Description:
The Quad Small Form-factor Pluggable ( QSFP or QSFP+) is a compact, hot-pluggable transceiver used for data communications applications. It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic cable. It is a industry format jointly developed and supported by many network component vendors. QSFP+ transceivers are designed to support Serial Attached SCSI,40G Ethernet, 20G/40G Infiniband, and other communications standards.The QSFP Transceiver include 40GBASE-SR4 and 40GBASE-LR4 for different applications. The AscentOptics 40GBASE QSFP+ (Quad Small Form-Factor Pluggable Plus) modules offer customers a wide variety of high-density 40 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider transport applications.

Installing and removing a transceiver module

WARNING!

Do not stare into any open apertures of operating transceiver modules or optical fiber connectors. The laser light emitted from these apertures might hurt your eyes.

CAUTION:

·     During the installation or removal process, be careful not to touch the golden plating on the transceiver module.

·     Before inserting a transceiver module into a port, make sure the transceiver module aligns with the port correctly.

H3C transceiver modules are available in three types:

·     Bale-clasp latch transceiver modules—Include CFP2, QSFP+, SFP28, SFP+, XFP, and SFP transceiver modules. For the installation and removal procedure, see "Installing and removing a bail latch transceiver module."

·     Pull latch transceiver modules—Include QSFP28, CXP, and QSFP+ transceiver modules. For the installation and removal procedure, see "Installing and removing a pull latch transceiver module."

·     Transceiver modules with captive screws—Include CFP transceiver modules. For the installation and removal procedure, see "Installing and removing a transceiver module with captive screws."

Installing and removing a bail latch transceiver module

This installation method is applicable to the CFP2, QSFP+, SFP28, SFP+, XFP, and SFP transceiver modules. The following procedure uses a QSFP+ transceiver module as an example.

Installation procedure

1.     Remove the dust plug from the target fiber port.

2.     As shown by callout 1 in Figure 3, close the bail latch upward to catch the knob on the top of the transceiver module.

3.     Grasp the transceiver module between your thumb and index finger and correctly orient it. Align it with the fiber port and push it gently into the port until you feel it snaps into place. See callout 2 in Figure 3.

Transceiver modules and fiber ports have disorientation rejection designs. If you cannot insert a transceiver module easily into a port, the orientation might be wrong. Remove and reorient the transceiver module.

In case of limited space, you can gently push against the front face of the transceiver module instead of the two sides.

4.     Grasping the fiber connector between your thumb and index finger, align it with the transceiver module optical bore and push it into the bore.

Transceiver module optical bores and fiber connectors have disorientation rejection designs. If you cannot insert a fiber connector easily into a transceiver module optical bore, the orientation might be wrong. Remove and reorient the connector.

5.     If you are not to install an optical fiber, insert a dust plug into the transceiver module bore.

Questions & Answers

• Can this SFP+ module work at lower data rates (155Mbps) than specified?
  Yes, it can work at 155Mbps. 
• What is the Tx power and Receiver Overload of 1G EX?
  TX Power: -5 ~-0 dBm. Receiver Overload: -3 dBm
• I notice that the 1G LX/LH supports both SMF and MMF. So what's the diffrence?
  If you use MMF cables like OM2/OM3/OM4, the max diatance is 550m. If you use SMF cables, it can reach up to 10km. So you can choose cable type according to your application.
