General Description

Physical layer modules

The newest module standard is the enhanced small form-factor pluggable transceiver, generally called SFP+. Based on the small form-factor pluggable transceiver (SFP) and developed by the ANSI T11 fiber channel group, it is smaller still and lowers power than XFP. SFP+ has become the most popular socket on 10GE systems. SFP+ modules do only optical to electrical conversion, no clock and data recovery, putting a higher burden on the host's channel equalization. SFP+ modules share a common physical form factor with legacy SFP modules, allowing higher port density than XFP and the re-use of existing designs for 24 or 48 ports in a 19-inch rack width blade.

Optical modules are connected to a host by a XAUI, XFI or SFI interface. XENPAK, X2, and XPAK modules use XAUI to connect to their hosts. XAUI (XGXS) uses a four-lane data channel and is specified in IEEE 802.3 Clause 47. XFP modules use a XFI interface and SFP+ modules use an SFI interface. XFI and SFI use a single lane data channel and the 64b/66b encoding specified in IEEE 802.3 Clause 49.

SFP+ modules can further be grouped into two types of host interfaces: linear or limiting. Limiting modules are preferred except when for long-reach applications using 10GBASE-LRM modules.

FAQ

1. Question: Can the 40G QSFP+ LR4 transceivers direclty work with 10G LR transceivers for 4x10G connectivity?

Answer: No, the 40G QSFP+ LR4 Transceivers cannot work with 10G LR transceivers directly because the 40G QSFP+ LR4 Transceivers uses LC connectors instead of MTP/MPO connectors. If you need transceivers to have 4x10G connectivity, the QSFP-PLR4-40G Transceivers are highly recommended.

2. Question: Please, what is the product warranty? Thank You.

Answer: All Fiber Optic Transceivers share 3-year standard warranty.

3. Question: What Is Single mode SFP?

Answer: There are stronger tolerances for the single-mode fiber optics used in SFP. The pumice is smaller and the length of the laser wave is narrower. This means that the SMF has the ability to have high bandwidth and long distance for transmission. One-time SFP (SMF SFP) runs mainly at wavelengths of 1310nm and 1550nm and is mainly used in the transmission medium, 2 km, 10km, 40km, 60km, 80km, and 120km. The colorful coded claw and colored lead on the label are usually blue, yellow, or purple. The optical fiber patch cord has a yellow color.

4. Question: What is your lead time for sampling?

Answer: It is about 1-3 working days after payment received.

5. Question: What is your delivery term?

Answer: Ex Works, FOB Shenzhen, discharge port is what we always do so far.

6. Question: Do you ship internationally?

Answer: Yes, we can ship anywhere you would like. If we receive your payment slip, we will ship the goods via our delivery forwarder or on your shipping account number. To calculate the best shipping cost for you, please kindly inform us your post code. If you need us to declare the amount to reducing the import tax, please discuss with our sales on line.
