About optical transceiver modules
Optical transceiver modules (also called fiber transceiver modules) transmit signals over optical
fibers and are suitable for long distance transmission.
The following information explains the major specifications of a fiber transceiver module.
Data rate
Data rate is the number of bits transmitted per second. Data rate is typically measured in Gigabits
per second (Gbps).
Transmission distance
The transmission distance of optical t ran sceiver modules is divided into short a nd long -range ty pes.
Typically, a distance of 2 km (1.24 miles) or below is short-range ty pe and a dist ance of 10 km (6.21
miles) is long-range type.

Transmission distances supported by optical transceiver modules are mainly limited by signal
Fiber grade
Fiber diameter (μm)
Modal bandwidth at 850 nm (MHz*km)
attenuation and dispersion suffered during the transmission of fiber signals over fibers.
•Signal attenuation occurs because of absorption, dispersion, and leakage over the media as
light travels through optical fibers. This attenuation increases in direct ratio to transmission
distance.
•Dispersion occurs because a fiber transmits light with dif ferent wavelengths at different speeds.
Light with different wavelengths r eaches the receiving end at different t ime. This results in
spread and blurred pulses.
Central wavelength
Central wavelength represents the wave band used for optical signal transmission. The following
central wavelengths (wave bands) are available for common optical transceiver modules: 850 nm,
1310 nm, and 1550 nm.
• The 850 nm wave band is used for short-reach transmission.
• The 1310 nm and 1550 nm wave bands are used for middle-reach an d long-haul transmissions.
Fiber
Fiber types
Fibers are classified into multimode fibers and single-mode fibers.
•Multimode fibers
Multimode fibers (MMFs) have thicker fiber cor es than single-mode fibers and can transport
light in multiple modes. However, the intermo dal dispersion is greater and worsens as the
transmission distance increases.
Multimode fibers can be classified into mult i ple grades according to their diameters and modal
bandwidth, as shown in Table 1. The modal bandwidth is a comprehensive index that reflects
the optical characteristics of a multim ode fiber. The modal bandwidth of a multimode fiber is
equal to the modulation freque ncy of the maximum modulation f requency pulse that can pass a fiber × the fiber length.
International Telecommunication Union (IT U) defines multimode fiber types in its G series
standards. The m ost commonly used multimode fiber is defined in the ITU G.651 standard. The
G.651-compliant fiber transmits light in th e wav el ength ran ge of 8 00 nm t o 90 0 nm or 1 200 nm
to 1350 nm.
Table 1 Multimode fiber grades
OM3 50/125 2000
OM4 50/125 4700
•Single-mode fibers
Single-mode fibers (SMFs) have a small core size (typically 9 μm or 10 μm) and can transmit
light in only one mode. Single-mode fibers suff er little intermodal di spersion and are suitabl e for
long-haul communication. Single-mode fibers transmit light at the central wavelength of 1310
nm or 1550 nm.
Telecommunication Industries Alliance (TIA)/Electronic Industries Alliance (EIA) defines that
single-mode fibers use yellow outer jackets wit h an " SM" mark.
ITU defines single-mode fiber types in its G series standards. The most commonly used
single-mode fibers are defined in ITU G.652 and G.655 standards. Table 2 describes features
of the G.652 and G.655-compliant fibers.

Wavelength (nm)

Applications
CAUTION:
Cover the connector with a dust cap when it is not connected to optical fibers.
Fiber diameter is expressed as core diameter/cladding diameter, in μm. For example, 9/125 μm
represents a fiber core diameter of 9 μm and a fiber cladding diameter of 125 μm.
As a best practice, use the following fiber diamet ers for the HPE Comware-based devices:
• G.652 standard single-mode fiber—9/125 μm.
• G.655 single-mode fiber—9/125 μm.
• G.651 standard multimode fiber—50/125 μm.
Connector
Connectors connect transceiver modules to the transmission media. The following information
describes the connectors used by the transceiver m odules for the HPE Comware-based devices.

HPE transceiver modules use only female M PO connectors, whic h have guide holes in the e nd face.

• Physical contact (PC)—End face polished flat.
• Angle-polished contact (APC)—End face polished with an angle, typically 8°.
MPO connectors are available with 12 fibers (see Figure 3) or 24 fibers (see Figure 4).

Optical parameters
The following are the major optical parameters:
•Transmit power —Transmit power is the power at which the transmitter of an optical
transceiver module transmits optical signals, in dBm.
•Receive power—Receive power is the power at whic h the re ceiver of a optical transceiver
module receives optical signals, in dBm.
The transceiver module specifications in this guide provide the average transmit and receive power
ranges.
